Dear Experts

I have 3 analog input modules , model number is 6ES7134-6GF00-0AA1. .

First Analog module is inserted in white base, model number is (6ES7193-6BP00-0DA0). while remaining 2 AI is inserted in dark BASE , model number is (6ES7193-6BP00-0BA0).

All system was running perfectly, but suddenly my breaker that was powering up AI module got trip. I checked my wiring ,supply ,everything was fine then i checked base L+ and M terminal, it was short. Now all these 3 modules are not powering up.

Secondly I read these base has isolation and external short protection.

I want to know expert view that dark AI modules got effected due to white base because in AI drawing 3A fuse is there may be its blown and it seems that white base unit did malfunctioning.

Thanks in advanced.
