Siemens FM350-2 Counter Module Configuration Problem

Dear Experts,

We are currently encountering configuration problem with FM350-2 used for counting and totalizing functions. When we configure the FM350-2 and load the FCs and DBs to the CPU, an error appears, indicated in the diagnostic buffer. For your reference, attached is the diagnostic buffer sreenshot. Also, we have a redundant S7-400 (CPU 414-5H) and 5 Remote IOs utilizing Profibus ET-200M.

Indicated in Siemens website, the FM 350-2 is configurable using ET-200M with a S7-300/S7-400 as master (http://w3.siemens.com/mcms/programma...#FM_20350_1_20).

Also, indicated in the manual, the FM350-2 can be installed in distributed IO using a specified ET 200M. (Please see attached). Iinitial selection for ET 200M is 6ES7 153-2AA02-0XB0, which is stated supported in the manual however, due to the module being phased out and a replacement introduced, we migrated to 6ES7 153-2BA02-0XB0. Since this seems to be the upgraded product, I believe it should support the previous function of the old part number.

May I request some advice on how the concern can be resolved? 

Thank you.

hi Ryan Fernandez,

according to the diagnostic-buffer, this is an programming error.

in FC7 is a writing access to an global-DB-address (address 8) that doesn´t exists.

Have a look in the  FC7 to detect the error.

hope this helps,

regards,
