Settings for communication monitoring and communication buffer

Introduction
Communication monitoring helps the user program respond to a missing connection to batch
control.
The communication buffer saves all BATCH data (for example, status changes).
Communication monitoring
The unit block provides outputs to determine the communication status between PCS 7 OS
and the BATCH Control Server. The outputs are called:
● AS-OS_ERR: Lifebeat monitoring for the communication between AS and the BATCH
● Q_ERR_COM: Communication status monitoring between AS and BATCH Control Server.
Operating principle of output "AS_OS_ERR"
If the lifebeat does not start after an interval you set with BATCH, then the block UNIT_PLC
sets the output AS_OS_ERR = 0. The user program can then respond to the missing
connection to batch control. Output AS_OS_ERR is reset to 1 after the connection is re-
activated (and transmission of the Lifebeat" signal has resumed).
● SP_COUNT = 0: deactivated/VA_COUNT constant 1
● SP_COUNT > 0: VA_COUNT is decremented at intervals of seconds, starting at
