I don't know anything about Mistubishi PLCs, but in order to get a reply on this thread you are going to have to give out a bit more information!

What are your inputs? Outputs?
What is your application and/or purpose?

Hopefully the answer to these short questions will get you some help!

download this manual JY997D16701-J

Firstly you must tell the unit its current (4-20mA) so therefore if you are using CH1 on Module 1 then you would:

M8000
-----[]---------------(M8260)

Then simply the analogue value will be in D8260 (as a value 0-1600 from memory).

This is basically it but the manual has it all.
