When I connected the first transmitter to channel 0 and checked theraw value in PLC, itwas fine with value 975. Once I connected the second transmitter to channel 1 and checked the raw value, it showed -32767 in both channel 0 and channel 1. When I disconnected the second transmitter (channel 1), the channel 0 value was back to normal 975. I had test with channel 0 and channel 2, channel 0 and channel 3, channel 0 and channel 4 with different transmitters. Once the analog card was connected 2 or above transmitters, it was given value -32767. I also measured the mA value with multimeter, the transmitters were given some mA value which was normal. Please advice. Thank you very much. Best Regards, Kok Wai Weng
