I recently added a new device to a Modbus RTU (RS485) network, using a HMS-EN2SE-R (in master mode) to communicate via Ethernet/IP to a ControlLogix PLC. I have two devices on the Modbus network. I can successfully read the data from these devices, and their values matchup with the physical readouts on the devices. However, on the HMS-EN2SE-R, LED 5 flashes green several times, then goes solid red for a few seconds, before returning to flashing green and repeating. Within the configuration manager, the subnetwork status has a constantly incrementing value for Retransmission Error, and Node Missing indicates that node 01 is missing. As stated, all data is coming in correctly from this device, so it does not seem like the node could be missing. I have tried varying baud rate, stop bits, message delimiter, and parity, all to no avail. How can I get rid of these errors?
Node 01 is the original device, and node 02 is the new addition. Within the configuration manager, all three green indicators along the bottom of the window are green.
Message delimiter = 50
Thank you for any help you can offer,
