Title: DO Issue
Post by: ccdubs on July 11, 2016, 01:27:06 AM

Hi,

I have a FMD88-10 (Rev 3) which is showing something unusual. Digital outputs 1-4 aren't working correctly and when energised in the code, they don't turn on (sometimes they flicker) but the RTC error light flickers.

Any ideas what the cause may be?

Thanks

On FMD PLCs, the 3 status output LEDs and the output 1 to 4 are linked to the same circuit. So it is likely to be some component damage on that part of the circuit. Please email support@triplc.com to request for RMA so that we can inspect and repair the board.
