Description
HIMA F7126 Power Supply Module
F7126 connects the PLC to the field equipment after the initial commissioning is qualified. Comprehensively check the entire PLC control system before formal commissioning, including power supply, grounding, device connection lines, I/O wiring and so on. In the case of ensuring the correctness of the entire hardware connection can be sent to power. The PLC control unit’s mode of operation is set to “RUN” to start running.
F7126 is used to input automatic / manual switching control signals. SB3 and SB1 buttons, although both use the X1 terminal, but in fact represents a different logical meaning. The secondary tube is used to cut off parasitic signals to avoid the generation of error signals. This one input can reflect the state of the two input signals separately and succumb to the input port.
Repeated debugging to eliminate possible problems. In the debugging process can also be based on the actual needs of the hardware to make appropriate changes to the old with the software debugging. Should maintain a long enough running time so that the problem is fully exposed and corrected. Trial run without problems can be solidified in the program has a long memory function of the memory, and make a backup (at least 2 copies should be made).
