First, Siemens PLC maintenance
1, maintenance procedures, equipment, periodic testing, adjustment provisions
(1) half-yearly or quarterly inspection PLC cabinet terminal connections, and if time to re-loose strong local connection;
(2) of the cabinet to the host power supply voltage of the monthly re-survey work;
Second, the provisions of cleaning equipment on a regular basis
(1) every six months or a quarter of the PLC to clean, cut off power to the PLC power supply to the power rack, CPU board and input / output board in turn be removed to purge, clean and then in turn installed in situ, will all link to resume evacuation call and start the host PLC. PLC box carefully sweeping health;
