I have an Allen Bradley 1785-20/E and its STAT light is flashing me a code of Quick 9 and Slow 7 - 3 which means "Fault Asserted" according to the I/M. Fine. Considering I'm repairing this module on the component level, having investigated the obvious causes already. does anyone know specifically what this function code is talking about???? I also have a solid red B Channel light and comms on neither DH nor ENET. I would like to know at least the internal circuit area. Many Thanks
