FP TC 120 module does not work

[Renzo]

I have a FP-TC-120 module connected to a FP-1600 Ethernet module. But the software FieldPoint Explorer seems not to recognize it. It recognizes my FP-1600 module, and a FP-AI-110 module also connected. The FP-TC-120 power LED keeps flashing frequently, and the Ready LED does not light. What can be happening? I have tried everything, but it does not work at all.

Check the pins between the FP-TC-120 and the terminal base and between the terminal base and the next terminal base. If possible, try the FP-TC-120 in a different terminal base. If the problem follows the module, contact National Instruments for an RMA.

Most probably the LED that flashes is Status LED on the TC-120..In case power LED flashes then you have problem with the power of your module.
In case the STATUS LED is flashing in some sequence you must check what is that sequence..1 flash / 2 or 3 in any case you can find in the user's manual what does that sequence means (specific error in the status of the module).

Actually, technically, the FP-TC-120 module does not have a STATUS LED. Network modules have STATUS LED's that will flash a number of times, pause, and flash again but I/O modules do not. All I/O modules have Power and Ready LED's and some I/O modules have additional LED's.

The FP-TC-120 has an LED on each channel to indicated Open Thermocouple detection. In an I/O module, a Power LED that is failing to turn on wil typically signify that one or more components in the system is damaged. The most typical example would be bent pins between the terminal bases or between the I/O module and the terminal base. Alternatively, some forms of damage to the I/O module could also conceivably cause this sort of failure mode. In any case, once the faulty component
is isolated (terminal base or module), it will probably need to be sent to National Instruments for repair.
