Hi,
I've just bought a SLC 50/3 with a few digital input / output cards.
I've attached a print screen of the I/O configuration.
What I want to do is figure out how to turn an outpu on and off with, i figure this is the first step in figuring out how to write a program,
I hoped it would be as simple as fitting a switch to the positive and negative of input 1 and a light or led circuit to the positive and negative terminals of output 1.
Obvioulsy it isn't as simple as that (no positive and negative terminals!)
I'm guessing the 24V input card needs 24V to energise the switch, and that this can be taken from the PSU 24V supply? There's a power out +24V and a power out com, theres also a com terminal on the cards, what are these for?
I guess the outputs are wired in a similar way?
I basically want to figire out how to wire a light switch through the PLC....any help would be greatly appreciated...
Thanks,
James.
