Hello RFP

simply ignore the "MPI_ADR" parameter of FC100 (SWR_START), its value is irrelevant if you use anEthernet (ISO) connection (or Profibus FDL) betweenthe two CPU's of your Software Redundant (SWR) system (just like the "LADDR" and "VERB_ID" parameters are irrelevant if you use MPI).

Your main problem at the moment though is that you can't use the onboard PN port for the redundancy link between the two CPU's and will require a CP for it (unless you ask Siemens kindly to release an updated SWR package that supports the PN port, since it has been 6 yeasr since the "current" version 1.2 came out).

Chapter 4.7 of the SWR manual list the possible networks and hardware requirements (and incorrectly calls the Ethernet CP a "CP 345-1" instead of CP343-1 but nevermind).

I hope this helps

Looking on the outputs of FC100:

RETURN_VAL is 16#8009 – according to the REDUNDANZ manual “Slave changeover lock could not be cancelled. Cause analysis by means of return value from SFC 58. Return value stored in EXT_INFO”

EXT_INFO is 16#8090

Interpreting EXT_INFO 16#8090 as an error of SFC58 would mean: Specified logical address invalid: There is no assignment in SDB1/SDB2x or there is no base address.

Looking on my hardware config, the base address of CP343-1 is 256, which is exactly what I put on the input LADDR of FC100.

Any help would be much appreciated
