Datasocket and FP2000

[Paolo_Squillari]

Hi,

I'm develpoing a RT acquisition/control system using FP2000. On FP 2000 I've wrote two main VI:
- TC.vi: time critical VI for acquisition and control of my system
- NP.vi: normal priority VI for data exchange with a host PC.
Host and FP comunicate using datasocket.

PROBLEM: when FP isn't connect to the network after about 12 minutes the status led become red and stay lit. I'm sure ther's no electrical problem (I've verified the same problem using one FP2000 alone).

some ideas?

Thank you,
paolo.

Paolo,

One possibility is that you have the the option "Halt if TCP/IP Fails" selected. To turn that option off, use the FieldPoint software and unselect the option in the Network Settings page under Remote Systems.

A second possibility is that your communications loop is not handling the lack of communications properly. You should include error handling that is designed to handle the lack of communications errors.

Regards,
Aaron

Paolo,
another thing you want to try together with Aaron's suggestions, is to download an really easy VI onboard the FP-2000 and see if the red status led lights up again after 12 minutes.
An easy VI could be a simple VI that turns on/off 2 leds on the FP-2000 itself.
