Title: permanently latched input
Post by: gillecaluim on March 27, 2020, 09:32:17 PM

I have a FX1616-BA.  The DIO channel led #14 remains lit, even without any input and DIO #14-16 don't properly sense any input.  I've reset the board but nothing seems to fix this problem....is the board toast?

Did you ever remove the SmartTILE-Fx CPU board from the carrier board previously?

It sounds like the SmartTILE-Fx board may have suffered some damage.

However, the best way is to request for an RMA (email support@triplc.com) and ship the PLC back to our office for testing. It is likely to be repairable unless there was catastrophic damage to the board.

Please include your company name and contact person name when contacting us. Some explanation of what the PLC underwent would be helpful for diagnosis.

Never did anything to the SmartTILE-fx board.  I've already ordered another FX1616-BA because I need to get this HVAC equipment back to a functional status.  I'll email for an RMA.
