I am migrating an application on an Allen Bradley SLC 500 PLC platform to interface to a compact Fieldpoint system. I previously used Fieldpoint modules (FP1000 and FP-TC120). Is the command set the same for the cFP as for the FP so I can speak to my Allen Bradley?

Both FieldPoint and Compact FieldPoint use the functions in the 'FieldPoint' sub-palette in LabVIEW. You may need to upgrade your FieldPoint driver, but the commands are the same. Aside from updating the "FieldPoint IO Point" constant or control in your code, you should be able to use the same program without any difficulty.

Sorry for the mistake above. The commands have not changed, you should be able to interface with Compact FieldPoint in the exact same manner as you did with FieldPoint. Let me know if you have any problems.

Getting back to our discussion of last November on this, I am trying to get the two systems to talk via RS-232 with no success to date. Some of the opening BASIC commands to the Fieldpoint, which is on serial channel 2 of the Allen Bradley Basic Module I am using, are:
This is supposed to wake up the Fieldpoint (line 80) and configure the Fieldpoint Thermocouple module (in position 0 on the cFP-1804) for type T thermocouples with cold-junction compensation. Are these valid commands still? The comms are at 19.2K, 8, N, 1. I get either no green on the status light on the cFP-1804 or an occasional red blink on it.

How can I query a cFP-1804 for a unique machine ID or serial number using LabVIEW, traditional drivers used in LabVIEW and/or DSC. I wish to confirm that this is the cFP module that was configured with the system. ...terminal validation.
