In general, if incorrect readings appear on a new install then checking for proper installation and 

configuration would typically prevail as a cause versus an existing working module

where a hardware failure of some type (channel or module) would be more likely the cause.

Also, if multiple channels are experiencing these symptoms, disconnect all thermocouples

except one. This can help determine if it is external hardware or the module itself is the cause.

Before attempting to troubleshoot these symptoms, a great deal of work can be saved by first,

visually inspecting the module, and second, applying a thermocouple emulator directly to the module input in question. 

Make sure that the module is powered and communicating based on the status indicators. 

Red or flashing green status indicators signify a problem.

Make sure that the wiring is intact and correct and the cold junction sensors (CJS) are installed correctly for the correct wiring arm, 

terminal base, or removable terminal block.

If all looks correct, then remove the thermocouple from the channel in question and apply the emulator.

The ControlLogix® controller provides a scalable controller solution that is capable of addressing many I/O points. You

can place the ControlLogix controller into any slot of a ControlLogix I/O chassis, and install multiple controllers in the

same chassis.

ControlLogix controllers can monitor and control I/O across the ControlLogix backplane, and over network links. The

ControlLogix 5580 controllers have an embedded Ethernet port for a direct connection to Ethernet-enabled devices and

networks, and also support communication interface modules in the local chassis. To provide communication for

ControlLogix 5570 or ControlLogix 5560 controllers, install the appropriate communication interface module into the

local chassis.

ControlLogix 5580 and ControlLogix 5570 controllers are available with a conformal coating. A conformal coating

provides a layer of protection against contaminants and humidity to help protect the assembly and extend product life in

harsh, corrosive environments. Products with a conformal coating have a ‘K’ suffix at the end of the catalog number.
