FieldPoint FP-1000 DAS behaves unexpectedly

[CLiu]

Hi all,

My FP-1000 DAS has the following configuration:

FP-1000 | FP-DO-400 | FP-AI-111 | FP-AI-112 | FP-RTD-122 | FP-TC-120 | FP-TC-120 | FP-TC-120 | FP-TC-120 | FP-DI-300

I have my own software communicating to the FP-1000 using the optomux protocol.  At startup, it resets the DAS bank and executes initialization procedures.  Once that's done, it updates all of the above I/O modules every 1 sec.  The DAS always runs expectedly after the reset.......  but after running for a while, it starts to return incorrect msg back to my program.  I have attached a log file showing the optomux commands sent to / returned from the DAS. 

In my log file, each line corresponds to a optomux msg.  The ones start with << are msgs from my program to the DAS, and the ones with >> are msgs from DAS to my program.  Everything seems to be okay until line 415 and below, the msgs recevied @ 00:00:37.

I have no idea why this is happening...  Your help is greatly appreciated.  Thank You

Christopher,

Are you using LabVIEW to communicate with your FP-1000? Are you using the Optomux VIs? If so, what is the error that you are getting? Why do you believe that the response is faulty? If you are not using LabVIEW, then how are you accessing your serial port? Are you getting any errors from that API? Please let us know!

Regards,
