NU8976a HIER466665R99 output module

Hardware failure on NMBA module. Switch power off and wait a few seconds before switching the power on again; if the problem persists, check that fieldbus parameter 02 MODBUS MODE is set to RTU wdg:rst.Continuous reboot. Fast blinking of ERROR LED for approx. 2 sec. repeated every few sec. Drive configuration write failed (DDCS link communication fault).
