[0041] The data acquisition module receives the control signal output by the PLC controller.

At this time, the second signal sending chip automatically sends a signal to the remote terminal again, and the coil of the third relay T3 is energized, and the fourth normally open contact of the third relay T3 closes. After the power supply terminal of the counter A is energized, it performs a count again.
