3.6.2 BATCH station multiple station system
BATCH station as multiple station system with client-server architecture
● A BATCH station multiple station system consists of BATCH clients (workstations) that are
supplied with data (project data, process values, archives, alarms and messages) from a
BATCH server via a terminal bus.
● There can only be one BATCH project with one BATCH server in a PCS 7 plant.
Only one BATCH project can be activated on a BATCH server.
● You can use a BATCH client to operate and monitor several PCS 7 systems. To do this,
start several BATCH client applications on the BATCH client and select different batch
projects at the start (each with one BATCH server). It is advisable to use a multi-VGA card
for such instances.
● You can achieve high availability for the PCS 7 system by configuring a redundant BATCH
server. In terms of the number of servers in a PCS 7 project, a BATCH server set up as
redundant is considered a BATCH server.

AS-based operation
If AS-based recipes are configured in BATCH projects, it is essential that the BATCH server
is connected to the system bus.
