Hi all,
I would like to know if there are some precautions to take when doing a welding nearby instruments.
Im asking this because today we weld a pipe, and although there was no instrument near that pipe, that pipe on the other side is welded to a tank which does have instruments.
After the welding we figure out 2 analog modules where showing OK status in the plc, but no channel was working, having the field power off bit set to 1.
We had to replace both of them, and when we took them out , in the chip in the corner, both of them had black area like they were blown (dont know how to post pictures)
Could this welding had something to do ?
PLC Contrologix, remote IO adapter AENTR, 1794-IE12 module used
Thanks!
