The module 32DO is the first on the rack after the IM, after it there are two modules 32DI and one 8AI. When one of the digital outputs is set, I have only 14-15VDC messured on output and the led related seems that is flashing. I replaced the 32DO Module and I had the same situation. Please help with some ideas Best regards
