BX-06RTD channels out of range

[Kristjan]

I have two systems where BX-06RTDs are misbehaving. These are relatively new modules. All inputs are used with Pt1000 sensors.

We started the systems a couple of weeks ago and all signals were fine. Then all of a sudden, all inputs on the BX-06RTDs went to -1480 with I/O error channels out of range. I corrected the issue by unplugging the lower 10-pin terminal (power supply to module) and plugging in again, now all was good. A few minutes later the situation came back, all channels out of range. Issue corrected again and a couple of hours later still good (fingers crossed).

Is this a known issue? What could be the cause?

We don't know of anything specific, but Host doesn't make that module, FACTS does. In their design the signal and logic sides are separately powered, and what you did would have rebooted the signal side. It sounds like the PLC and logic side are working fine.
