Added parameter(s) were selected from I/O Engineering drop down menu. Tried parameters were typically "d0.xx" diagnostic parameters. For example, I have tried d0.0, d0.1, d.12, d0.13...... Configured parameters were shown in the PLC engineering data layer after downloading to the Core. EtherCat screen show all devices status with green circle with a check mark. EtherCat Master does not show any error message and only indication of malfunction is xFC01_Rexroth_mode shows "pre-op". All other devices in the EtherCat network showed "op". No error message were shown other than xFC is stuck in the "pre-op" and will not transition out even after the system complete power cycle. EFC firmware is "FWA-EFC01*-NNN-03V39-NN" and MEP fiemware is "FWAxFC01-MEP18" . Thank you for your support and please let me know if you need further information.
