Rules
Observe the following rules when configuring:
•
With mixed configurations, the following maximum configuration is possible:
– 31 slots for ET 200SP modules (IM 155-6 DP HF and IM 155-6 PN ST)
– 63 slots for ET 200SP modules (IM 155-6 PN HF and CPUs)
– 16 slots for ET 200AL I/O modules
– 1 slot for BU-Send/BA-Send 1xFC
– 1 slot for server module.
• The mixed configuration may contain a maximum of 31 (IM 155-6 DP HF and
IM 155-6 PN ST)/63 (IM 155-6 PN HF and CPUs) ET 200SP I/O modules.

Configuring
Observe the following points when configuring:
•
BU-Send/BA-Send 1xFC and server module must be configured. There are no parameters
for BU-Send/BA-Send 1xFC.
• Arrangement of the modules in the configuration:
– Configure the BU-Send/BA-Send 1xFC modules downstream from the interface module
in slot 1. Position the ET 200SP modules behind it.
– Configure the ET 200AL I/O modules from slot 66 (PROFINET)/67 (CPU)/34 (PROFIBUS).
• The layout of the modules represents a preset configuration and is independent of the
configuration control.
• The system redundancy S2 function is not available in a mixed configuration.
