Hi,
I have a fieldpoint system that consists of 2 controllers and approximately 10 modules. The modules include a mixture of thermocouple, analog outputs, analog inputs, digital outputs and digital inputs. The system has been operational for more than 2 years without a problem.
Recently, the communication with one of the FP-TB-10 modules stopped. This module has 8 channels of DI and 2 channels of AO. The only visible symptom of a problem is that the "ready light" does not light-up at all during or after powerup. By perusing the knowledgebase and discussion forums, this seems to indicate that the module is not properly booting up.
I am trying to pointpoint where the problem may lie - with the FP-TB-10 module, with the individual channels, or perhaps with the inputs. Or maybe I have some sort of loose connection?
I have another FP-TB-10 module right next to the malfunctioning unit - it works fine. Therefore, I suspect the system power is OK.
I tried removing all of the individual channels from the malfunctioning unit and then powering it up. The result was the same - no ready light.
Any other ideas? Suggestions?
Thanks,
