Set the DIL switches for the individual components as follows:
•
IM153-2 FO PROFIBUS address 3
•
SM 326F DI 24 Module address 8
(Only found on the reverse side; only in steps of 8)
•
SM 326F DO 10 Module address 24
(Only found on the reverse side; only in steps of 8)
Set the mounting rack numbers 0 and 1 for the synchronization modules.
Connect actuators, or alternatively terminating resistors, to the output module (e.g.
between 12
Ω
and 3.4 k
Ω
with 1 watt), or disable group diagnosis for unused
channels in the hardware configuration.
Interface restrictions between S7-400 CPU and ET 200M IO
The ET 200M components which can be used in safety mode depends on the
safety class and the use of a safety protector in the ET 200M configuration:
•
If you comply with the requirements of safety class SIL 2 or use a safety
protector in SIL 3 in ET 200 M, you can use the IM 153-2 for S7 F/FH
Systems or the IM 153-3 only for the S7 FH Systems and you can set up the
PROFIBUS-DP with the copper cable (as in standard mode).
•
If you don’t use a safety protector in SIL 3 in ET 200M, you must connect the
PROFIBUS-DP lines of the S7 F/FH Systems with fiber optic cables. You can
only use the IM 153-2FO.
