Hi,

I have another question regarding replacement of 6ES7315-2AF03-0AB0 to 6ES7315-2AH14-0AB0; where i change the HW config plc module only.

The system is connected via profibus to control IOs and Drives; the current issue is with the drives after the PLC replacement.

Its connected to 4 6SE7090-0XX84-0FF5 (MDW) and 1 6SE7090-0XX84-0FF5 (SG70).

The issue is with 6SE7090-0XX84-0FF5 (SG70); where i’m unable to send a run command through communication; everytime i tried to run.. an alarm occurs, and the keypad in a split of ms shows 010 008 then back to 009.

As for 6SE7090-0XX84-0FF5 (MDW) runs well

Can anyone guide me on solving this problem?

Thank you
