Hi, I have a system of PLC all connected to a ethernet network, some PLC's have H4-ECOM and some have H2-ECOM and H2-ECOM100. They are all communicating with a SCADA system via OPC server. Sometimes it happens after a power loss that the communication to the H2_ECOM / ECOM100 modules stops working. If I try to edit a link to the PLC in DS I get a error messages. The modules show up in NetEdit and if I update the firmware to its current version ( no change) it starts to work again. I wonder what might be the fault and even why this "fix " is working ? Could it be that by updating the firmware, I'm resetting the module. I tried to power-cycle the PLC but that was not enough. Any thoughts ? I'm not having this problem with 5 other modules that are H4-ECOM or 2 pcs of H0-ECOM. Best regards, Gudmundur Ben
