Create and download symbol file

For CPU with FW V1:

If PLC hardware is available, please use login / download program to copy the .sdb file automatically into Gateway folder, e.g. C:\WINNT\Gateway Files.

If there is no PLC, the .sdb file should be copied into Gateway folder by hand.

When OPC server is started, the .sdb file will be copied to e.g. C:\WINNT\Gateway Files\Upload for Gateway communication.

For CPU with FW V2:

Following option can be chosen to download the .sdb file also to PLC.

When OPC server is started, the .sdb file will be copied from PLC (if available) or from Gateway folder to C:\WINNT\Gateway Files\Upload for Gateway communication.

Note

Do not configure the program as a cyclic program, please use a task configuration. Call the PLC Browser and have a look to the task time (command tsk in the command line).

For example the program has a cycle time of 40 ms, use a task time of 50 or 60 ms.

So the CPU has time to answer the OPC request from the OPC Server between the tasks.
