I have this old Siemens S7-400 PLC with a CP-443 comm module, and an AI, AO, DI and DO modules. I have access to TIA software
I am just starting to learn PLCs.I have 120V going into the main PS-407 module. How do I get 24V DC to the I/O cards? I do have a separate 24V PS. Do I need to wire the V+ and V- to each module? Where? What terminals?
Can anyone walk me through the steps of wiring up a simple PB switch to the DI input module, and an LED to the DO output module.
I think I can handle the software portion (TIA) portion, just need help with the hardware.
