Address embedded I/O, MicLog 1500

Dave Sell · Jul 22, 2009

How do I address the on-board I/O points on the MIcrologix 1500?

We will use the BWA model which I think has 12 inputs and 12 outputs, but I don't know from RSLogix 500 which bits these are.

I think it's O:0.1/xx but not sure - do not have a model here to test, couldnt find it in any manual or help file.

Thanks!

I:0/xx, O:0/xx

Dave Sell · Jul 22, 2009

which bits? xx could be 0 - 15, but there's 12 physical outputs...

Thanks again.

Dave Sell · Jul 22, 2009

OK wait - it could be:

O:0.0/xx
O:0.1/xx
O:0.2/xx
O:0.3/xx

xx = 00 to 11

Dave Sell · Jul 22, 2009

OK so which line is it, 0, 1, 2, 3?

Is it O:0.0/xx (0 - 11)?

Thanks again!

your '.0' is optional and unnecessary since there's only one word of inputs and outputs

Dave Sell · Jul 22, 2009

OK cause I see like 4 16 bit lines of output memory... see attached.

On input it goes I:0/0 thru I:0/11

Output depends on model but same basic idea O:0/0 - O:0/6

Even though your table show bits available they really are not all used.

Thanks Bernie/Clay, I got it now
