Synchronization
4-24
The PLC programming in this example does not depend on the protocol
and can therefore be used for H1 and TCP/IP.
This PLC program is used in both CPUs.
Synchronization of the interfaces
In the start-up OB OB100 of the CPU the interface used on the CP has to
be synchronized by means of the handler block SYNCHRON.
OB100 verifies that the synchronization procedure was completed without
errors. If an error is detected, the error number is entered into MW100.
Operation block OB100:
