Conventional technical configuration (3):

In the first water treatment PLC control system, a total of 6 on-site PLC control stations (PLC1∽PLC6) are set up. Each PLC control station realizes linkage logic control between equipment, realizes process control and feedback control of equipment according to process requirements, and controls important equipment on site. Or start, shut down, stop and set operating parameters of the unit, and monitor the operating conditions of equipment and instruments.

Now according to the following situation description and requirements, make the optimal ABB PLC configuration for the PLC1 on-site control station (water pumping station) (including power module, CPU, I/O module, CPU and I/O base plate, remote I/O module and base plate, FBP adapter, programming cable, battery and other accessories).

Configuration:

Total point configuration requirements: AI: 90 AO: 60 DI: 130 DO: 130
