Do you have the analog version of the ML1000?(see picture below) If so then you will need something to convert
the thermocouple to 0-10v or 4-20ma for the ML1000's analog inputs to read. See link below for one vendor there are many more.

Thermocouples produce micro-milli current ranges, not capable of a standard 4-20mA analog input. You would need to use some expansion IO on any of the micrologix range of controllers. But unfortunately I don't think you can expand the 1000.

Perhaps a 3rd party interfacing device would work.

Someone chime in here if I'm wrong.
