Greetings ishmail,
and welcome to the forum ...
Ron Doran is correct - you’ll need block transfer instructions to communicate with your analog modules ... we can help - but we’ll need more information in order to give you specific detailed suggestions ...
first, please tell us what addressing mode you’re using ... check the setting shown below ... (important! do NOT trust the setting shown in the I/O Configuration feature) ...
next, we’ll need to know how you’re wiring your input modules ... single-ended or differential ... and what scaling you want to use ... basically we’ll need to fill in the following screen ...
the button that I’ve circled is VERY handy - it will automatically write the Block Transfer rungs for you ... but you really should have everything else set up correctly before you do that step ...
also, we’ll need to know exactly which slots you have your modules installed in ... the best way to tell us is by “lettering” the slots “A” through “M” instead of using numbers - with the processor in slot “A” ... this will help remove the ambiguity that often results with different addressing modes ...
also, we need to know the exact catalog numbers of your modules ... for example: 1771-IFE/A and 1771-IFE/B modules have different setup requirements from 1771-IFE/C modules ...
anyway ... the more you tell us, the more we’ll be able to help ...
and don’t forget to set the jumpers hidden INSIDE the IFE modules ... let us know if you need help with those ...
