Hello everyone,
I would like to share this thermal image I got, if anyone is interested. It's a V700 with V200 connected on the back of it.
Outside temperature was around 20°C, cabinet could be better ventilated.
Probably not. There is no temperature reading in PLC V130 online SI14=0.
Although the temperature sensor is exactly on the board, but it is probably used for another purpose - to compensate for the temperature of the TC cold junction during measurement.
Experimental result update:
There is no PLC temperature SI14 readings in V130.
But if we sw ON any of TC input in SI15 appear temperature readings from internal TC cold junction sensor.
I try different combination - if
