Hello memebers,

I am having a situation whereby when I try to modify some SIMOCODE DP  (old version) parameters they refuse to accept the changes that I make through the DPV1 connection,now I got about 100 of those devices in a motor control center.

The attached is a picture of the message I get when I try to load the modified parameters back to the SIMOCODE via the DPV1 connection. What changes should I play around with on the SIMOCODE or PLC ?

Hi,

at the following FAQ you find a description of the similar behavior at SIMOCODE pro.

FAQ:
Error message: "Parameter changes not allowed in the current operating state ..." in the case of SIMOCODE pro

The possible reasons are the same. There is one difference: disconnecting PROFIBUS line does not help with SIMOCODE-DP 3UF5.

Please rate my answer if this was useful. Thanks!

Best Regards
