Common troubleshooting:
1) PLC can not collect data
A: Please check the device output type; whether the device is powered on.
2) the collected signal and the actual difference is very large
A: Please check the equipment range and data conversion relationship.
3) The transmitter output is beating
A: The distance between the transmitter and the collector is too long, resulting in signal disorder.
4) how to quickly determine the problem
A: temporarily do not take the post-acquisition equipment, multimeter to measure the transmitter signal output.
