BATCH control server

Definition
The BATCH Control Server is a component of SIMATIC BATCH. The BATCH Control Server
handles communication with the process and controls and monitors execution of the current
batches.
The BATCH Control Server does not have its own user interface. The BATCH Control Server
is started using the Launch Coordinator on the BATCH server or, in a redundant system, on
both BATCH servers.
BATCH Control Server tasks
The BATCH Control Server (BCS) performs a variety of detailed tasks. The most important
functions are the following:
● Establishing a communication connection to the automation system
● Generating the control recipe
● Downloading the control recipe to the automation system
● Processing the recipe synchronization
● Generating messages on the server status
● Controlling the redundancy mechanisms
● Failure monitoring (watchdog)
To acquire batch data (messages), there is a connection to the message server and to the
process data acquisition of the PCS 7 OS (WinCC).
Establishing a communication connection to the automation system
The BCS in conjunction with the communication channel (via S7 DOS) ensures the
communication with the process. It monitors the execution of the current batches.
In contrast to the PC-based concept, the AS-based concept has direct process access via the
communication channel.
Transferring step information and control recipe requests
The BCS transfers data to the AS via the S7 DOS communication channel. Commands and
parameters are sent to the automation system. The BCS receives status and process values.
