Rating 1. Thanks 1. Gold Member. Advanced Member. There is now confusion amd I'am not sure about things. Please see the attached file. There in they have mentioned that all CP software products can be operated with the CP Please remember that these settings are only made for the Windows firewall. If you use a different firewall, make sure that the same settings are also available with this firewall.
In this case, you do not need to take any further action. As an alternative, you can also make the necessary changes to the new firewall yourself. You will find a comprehensive overview in the online help of the "Communication Settings".
In this case, error-free execution of the program is no longer possible. Setting network adapters directly after Windows system logon. If you encounter this problem, you will need to restart the PC.
You can then continue as normal. The user therefore has standardized access options for all protocols of these products. When discovering computer names OPC UA Discovery , the names must differ by more than simply upper or lower case letters. Use the new OPC Data. NET control, this restriction does not then apply. OPC Automation interface is not released for multi-thread user programs. The OPC Automation interface cannot ensure data consistency if there is simultaneous access by several threads.
There is also a possibility of illegal memory access. The use of the OPC Automation interface in multi-thread user programs is therefore not released.
Automation Interface for Alarms and Events not yet available. Avoid this high utilization. If there is high CPU utilization, data change messages arrive more slowly. If you use consecutive calls for synchronous reading from the device or synchronous writing to device over OPC with DP-V1 protocols, make sure that this does not occur faster than the standard polling time.
The slaves then no longer appear in the address space, OPC items belonging to them cannot be used. The symbol editor must be closed while the configuration of the PC station is downloaded.
If a PC is used both as client and server for S7 services, for example S7 variable server, the connection property. You will find these parameters in the "S7 connections" properties. Otherwise connections may abort. The TTR time should be increased in the configuration user-defined parameters.
Then restart your OPC application. For more detailed information, refer to the "Commissioning PC Stations" manual. This is not possible for applications with an OPC interface. Release of the. NET Data Control. NET Data Control has been released for the following operating systems and compilers:.
NET 3. NET Framework 4. These control elements are intended for use within the OPC data control. Otherwise, the buffering of these data packets can lead to a lack of memory that can eventually cause the connection to be terminated.
When using configurations approaching the configuration limits, make sure that the OPC server has adequate free memory for managing data. OPC Data Access 3. This makes reading from the cache impossible. Function calls with longer execution times should be avoided to prevent other callbacks from being delayed. Changing languages in ongoing operation.
After closing all subscriptions, the language can be switched over. Once this has been recognized, repeat subscription calls periodically approx. If you want to achieve higher performance with a large number of items, disable the group first. Non-existent but configured symbol file prevents connection to the OPC server. A non-existent symbol file entered in the configuration prevents the use of symbols.
Connection establishment is rejected with an error message. The OPC server 8. COML S7 - no synchronization with existing local addresses during import. When importing a COML S7 configuration, the remote S7 partner addresses it contains are not checked to establish whether or not they are the same as local addresses on the PC station.
Avoid having the same addresses. If the OPC client wants texts in a language that is not available to the OPC server due to the configuration, it supplies these texts in the default language or if the text is not available in this language in English en-US.
If texts are not configured, the OPC server generates a default text. The naming of alarms, alarm sources and alarm areas must be translated and used consistently in multiple language configurations. Otherwise, alarms and alarm areas may be incorrectly assigned.
This includes connection names, alarm names, source and area names. The names must be written exactly as they were configured. Unconfigured alarm and diagnostics texts as well as source and area names are provided by the OPC server in lower-case letters and they must also be used as such.
The S7 OPC UA server decides the language used to form the node identifiers for area and source names of alarms according to the following rules.
The language is then also the default language in which it supplies localized text if the client does not select a language. English, if the language setting English was selected as the first or second language for alarm texts in the STEP 7 project. Default language if the language setting default language was selected for alarm texts in the STEP 7 project. English, if no language was selected for alarm texts in the STEP 7 project.
Default texts are then generated internally in English. S7 OPC UA server with large number of alarms and conditions available only 50 s or longer following download.
If you make use of the full released number of S7 alarms in German and other S7 alarms in English, and consequently with many alarms and conditions, the S7 OPC UA server will only be available after approximately 50 s or longer.
If your client registers before this time has elapsed, the connection establishment CreateSecureChannel to the endpoint of the server will fail. Default values, for example ms for the cycle time are then used. Once the validity of an OPC UA client certificate has lapsed, the cyclic renewal of the SecureChannel is also denied in ongoing operation. Connection diagnostics items only return one connection parameter for fault-tolerant S7 connections.
With fault-tolerant S7 connections, the following connection diagnostics items for the S7 protocol return only one of the available connection parameters:. If a configuration with S7 symbols is downloaded to a PC station and then a local COML S7 configuration is enabled in "Communication Settings", the previously loaded S7 target symbol file remains selected.
To change these, the access rights must be reconfigured STEP 7. Access via the IndexRange parameter to UA field elements of a node of the type array is not released. Locally configured alarm texts do not support browsing of the alarm name space. With locally configured alarm texts in the scores7.
In addition to this, when browsing the namespace of these connections, connections can be interrupted. If there is resource bottleneck on the S CPU, this may reject an acknowledgement temporarily when alarms are acknowledged. This is indicated by the OPC server with a communications error. In this case, the client should repeat the acknowledgment at later point in time. When setting the filter options of alarms to sources and areas in the "Set filter" dialog opened with the "Filter options" button in the AE view , note the following points:.
The settings in the "Browse process area" field are not decisive for the filter options used. The filter options which are relevant for the OPC client are the specifications in the fields "Source filter" and "Area filter". The settings in these fields are not identical to those in the "Browse process area" field.
For this reason, check the entries in the "Source filter" and "Area filter" fields and edit these entries, if necessary, without using the "Browse process area" field. Values when browsing without adequate privileges. Generally, the Web service writes its traces in two circulating files whose path can be specified with the "Communication Settings".
If these files cannot be created or written to due to an error, for example inadequate access rights, a context trace entry is generated. The context trace is an online trace provided by the Web service as long as it is running. It can be displayed with any browser, for example the Internet Explorer. To achieve this, "Trace.
If parameter "RequestOptions. ItemPath" is set to "true" or "false", the ItemPath in the path is returned and not zero. Depending on the required update rate of an OPC client, the call rate can also be slower. Communication Settings: Option "Use as target for S7 symbol download" not enabled. If you have configured S7 symbols, enable this option. Communication Settings: OPC protocol selection with symbols. One use case is to use symbols to provide a restricted address space with restricted access permissions.
The symbols can also be used with more than one selected protocol regardless of the type. If only one protocol is selected, the activate configuration is more efficient; only the selected protocol can be used in the symbols as previously. If different access permissions are specified for symbolic items in the Symbol Editor from close that actually exist, the actual permissions are returned when the access permissions are queried using the "ValidateItem" OPC method.
The "GetProperties" method returns the permissions assigned in the symbol file. Da, OpcRcw. Comn are supplied by the OPC Foundation. Please note: If you have not used a local copy of the previous.
Note the following:. The configurable default priority for alarms per EventID overrides the S7 priority configured in the instance data block as of OPC servers 8. The S7 priority configured in the instance data block as of OPC servers 8. Do not use and high numbers in exponential representation.
Instead use integers. Prior results are not buffered. This means that the entire name space must be searched again for every call, individual calls are therefore slowed down depending on the size of the name space.
For cyclic reading, we therefore recommend the use of subscriptions so that the name space does not need to be searched for every query. New error codes if "Immediate response when interrupted connection is detected" is configured. For the S7 protocol, the additional error codes 0xL and 0xL have been introduced with the meaning "no connection to the S7 communication partner, immediate error return configured".
If you want to correct the values of the variables on the OPC client, the following conversion can be made. This is suitable for C or VB. Add dt. Substract dt. Subtract dt. A change in the configuration may require a restart on the computer.
If components involved in a configuration change are still being used, it is possible that the Station configuration Editor reports the still active components and proposes a computer restart.
If necessary, disable the automatic startup of OPC client programs before the restart. As soon as the configuration changes have been made following the restart, the automatic startup of OPC client programs can be enabled again. All programs that were previously exited, can be started again.
Remember that a mixture of languages can occur on the OPC interface when the operating system language and installation language differ from the language requested on the OPC interface "localeID". Writing on a German system with an English "localeID". Reading on a German system with an English "localeID". During DP communication with communications processors CP 56x3 or CP 56x4 , when reading over OPC, the time stamp never changes unless the values have changed applies to both inputs and outputs.
The time stamp for changes to the tags is displayed. If you are unsure, use the default settings. If you have a large configuration, select a higher job timeout. With a large configuration approximately 10, items not only the communication delay on the network but also the processing time for OPC jobs on the OPC servers becomes relevant.
You should then select higher job timeouts of approximately 15 s for items, to avoid connection aborts due to the configured job timeout being exceeded. Select cycle times for the OPC server that are significantly shorter than the monitoring times. The cycle time configured for the various protocols of the OPC server should be selected so that it is significantly shorter than the shortest configured monitoring time recommendation: at least a factor of 5.
This ContinuationPoint must be specified when continuing to browse the next elements of the level. If, however, you have browsed a different level in the meantime between calling the function the first and second time, the previously obtained BrowsingPoint loses its validity and cannot be used to browse further elements.
These services require adequate rights for access to the folders in which the STI or ATI symbol files are stored and for the files themselves. Make sure that the "interactive" or "configured" users have "full access" to these files and folders:. OPC DA 3. If the IO device is unobtainable, the method call can take a long time. Programming recommendation: Implement exception handling for OPC interfaces. Writing DateTime variables in unspecified format is not permitted. Monitored data changes OnDataChange can be old until the confirmed update interval RevisedUpdateRate because data is read cyclically on the OPC server and in the underlying communication protocol of the PC station according to the update rate.
If the communication protocol signals new values to the OPC server shortly after a message has just been sent to the OPC client by the OPC server, this new value can only be signaled to the OPC client after the update interval has expired. The S7 connection is terminated only if the "Automatic connection termination after, e. The access permissions for symbols can be selected freely. These permissions are displayed when browsing. When accessing the items, these permissions may be further restricted by the OPC server.
When it is accessed, however, only writing is permitted since the system does not allow peripheral outputs to be read. The shortest possible update time is the cycle time.
OPC servers retain items that have been used in work memory. This memory is released again only after exiting the OPC servers. As a general rule, all configuration parameters, in particular timeout times, cycle time, alarms, must be matched up with each other depending on the plant configuration hardware and software , the configuration limits and the way the client and other active applications work. If the job timeout times are too short, this can result in connection aborts if larger jobs are sent at the same time by COM or UA clients, for example, when initializing, reading, writing, enabling and disabling larger amounts of items.
Where possible, select a timeout value default ms that is higher than the update rate for example ms by a factor of 10 on the OPC client display unit. If you are using a large number of SNMP devices for example each using approximately OPC items, the timeouts should be increased to the highest setting of 60 ms.
The update rates should be increased to approximately ms. You can test this with the ping function in a command console. If the name cannot be resolved, check in the Windows Firewall, to see whether "File and Printer Sharing" is permitted as an exception. An incorrect number of items causes an access violation.
Avoid such parameter assignment errors and provide an exception handling routine in the user program to deal with the exception. Only then can the values be used. If one of these connected OPC servers is shut down and reports this via its IShutdown interface, this status is indicated by a special icon for this OPC server, the monitored items belonging to it are displayed as BAD.
Other items of other OPC servers continue to be monitored and values continue to be generated. Reconnect the OPC server involved yourself; stop and restart monitoring and value generation of the DA view again because this registration is not automatically renewed. In the AE view of OPC Scout V10, line breaks are inserted automatically for event texts that are longer than the set column width, meaning that they can no longer be read in full. Solution: Increase the column width manually to view the entire event text, including associated values.
The user names and passwords used are saved in the user-specific configuration file when OPC Scout V10 is ended. Solution: After opening a saved project file, manually select the OPC server to be diagnosed. If a connection interruption occurs between OPC Scout V10 and the OPC server during use of the diagnostics view with activated monitoring, it is necessary to reactivate the diagnostics after the client-server connection has been restored.
Updating the alarm list, please ensure that refresh has been sent by the server. Are these events missing, press the update button again. OPC UA certificates are not indicated as trustworthy by the Windows certificate management if they were self-issued and not stored in the trustworthy storage folder. The Windows certificate management also indicates this as untrustworthy.
Net are. Both can be downloaded by corporate members at www. These programs have two operating modes. The "Use security" mode must be called with opc.
The client can then be restarted. The "Use Security" mode will now work. If you use the full range of configured alarms, your application must be able to process the shower of events. If you do not want this to happen, then use suitable filter conditions.
List of data blocks is only read out once from the S7 device after connection establishment. When browsing the OPC S7 namespace of S7 connections, the existing data blocks are listed as a separate branch. To reduce load, the list of data blocks is only read out once from the S7 device after connection establishment.
UA certificate management: first delete previous certificate before a new certificate can be accepted from the same client. If a remote UA client certificate has already been accepted in the UA certificate management in "Communication Settings", no further certificate can be accepted from the same client and domain.
First delete the previous certificate; the new certificate can then be accepted. As of OPC servers V8. Receiving alarms and events via unspecified connections. In Windows 7, alarms and events can be received via unspecified connections. No message configuration is downloaded for the unspecified connections so that the received alarms only contain the standard texts. This makes no statement as to whether the buffer was actually received and processed by the partner application.
OPC UA certificate management: local client certificate exists more than once. In specific cases it is possible that the network configuration of the address page of a PROFIBUS module is not activated automatically when the bus profile "Standard" is selected.

ACPI standby and hibernation mode is not supported. The "Energy saver" or "Sleep" buttons under the Start button must also not be used. This also applies to corresponding key functions on the keyboard or on the housing. If there is a change to "Power saving" or "Sleep", then depending on the hardware configuration, it is possible that the PVC will no longer wake up. To prevent the sleep mode, disable "Sleep" in the current profile:.
Power saver mode not allowed. The current profile is therefore adapted by the installation. A single service for which the Station Manager waits during startup was not started. The following error entry may be found in the diagnostics of the Station configuration Editor: "1 service s , which the Station Manager waits for when it starts up was were not started.
In this case, you can ignore the entry. This is then simply a delay and not an error. To check whether the plug-and-play manager is still running, follow the steps below:. If the status is still "Starting", the search for new hardware is not yet complete. Removing communication modules in configured mode. Recommendation for communications processors with preprocessing. After installing or removing new hardware, you must log on at least once as a user with administrator privileges.
Switching from configured mode to PG mode using the Station Configuration Editor or the communications settings. Programming via the C programming interfaces is supported for the following protocols:. S7 communication with C applications. Otherwise, these connections will be established when the UA protocol is activated and are no longer available for the C application.
Connection reestablishment. Reaction to error codes. The following functional restrictions apply to this version of the product. This service is not yet permitted.
This service can only be used on other remote devices. Variable services. Trace functions. The functions. Do not start an S7 application using the Windows Autostart mechanisms, Instead, use the Autostart functions of the "Communication Settings" tool to launch S7 application following startup. Section 3. The example is located on your PC with a bit operating system in:. For bit operating systems, there are two variants:. Note which operating systems are permitted for the software. To eliminate the problem, reboot your computer.
If the problem persists, please contact the Customer Support. After every configuration change when importing stations etc. To be able to assign a module uniquely during "Import station", the module type, the module version and the interface parameter assignment must match the actual existing hardware exactly. XDB import must only be done when there is no communication taking place between PC station and other partners. As long as the configuration of the PROFIBUS communications processors is not yet completed, modules must not be connected to the network of the operational system!
Randomly set addresses can cause problems on the plant bus! Before downloading or importing configuration data, the "S7 Connection Diagnostics" program must be exited. In sporadic cases, the following behavior can occur with special network configurations:. In this case, restart the download — and the download to the station will succeed. Avoid downloading to a PC station modifying the configuration at the same time. When downloading configurations, note the following:. After logging on, the "CCAgent State" dialog can be started in the information area of the taskbar.
Do not set the "Pause" option.
