A984 Requirements

[papafrancisco 0]

I have a A984-145 processor, P120 PS, a backplane for two IO cards. I only have the processor and PS. When I power up the PS I get a green LED. No indicators are on the CPU. DO I need IO? Maybe a terminating plug? It's been a while since I have touched a PLC. A newby all over again. Thanks

Nope, you don't need I/O or a terminator. Just a program. make sure the CPU is in the correct slot.
