Hi,
I'm using a 0-5V sensor on one of the AI on my TMD2424, sometimes, usually after power up the ADC reads zero, I give the 5V connector and the analogue input connector a tap and bingo, I have a reading.
Is the 0VDC for the analogue supply and the PLC 0VDC power supply connected internally?
I have removed and reconnected the connector a couple of time but there was no obvious sign of corrosion or mis-alignment.
I'll try another channel.
