Hey all,

I've got a 6ES7350-1AH03-0AE0 counter module that died. I bought a replacement of same model, though the firmware on my existing module is 1.0.3 while the firmware on the new module is 1.0.2

Will this be an issue? Was hoping for plug and play as the program is password protected by the original manufacturer. 

Hello,

This post contains the current firmware for the module:

Firmware Update for FM350-1 (6ES7350-1AH03-0AE0)

Regards
