I've got ET200M IM153-1 with 4 SIWAREX M modules mounted on the same rack. I'm trying to change one siwarex to different one (the same catalog number, but different firmware version - old is 0115, new is 0121). After I do that - there's no communication between siwarex and CPU (last values of data record are those from old siwarex and stay "frozen").
I thought the firmware might be too old, so I tried to load firmware version 0126, but when I do that, SIWALOAD says "CONNECT PC WITH SIWAREX MODULE".
I think I'm doing it right: connect to COM, set 2nd dip switch to ON, reset power and ENTER.
What can be the solution of my problem?
