output from ab slc 500 to an input on an ab micrologics. Output and input are pnp and 24vdc. Voltage is coming out of output fine, but when i go to the seperate control panel with the compact logics plc, then i dont read the 24vdc coming into input. I wonder if it is a different of power supplies... Thus i would either need to use relays, or maybe i could tie the negatives of the separate power supplies together(would be easier)? Would tieing the negatives together cause an issue?
Your thoughts? Thanks in advance.
