I’m using a HMS-EN2SE-R for Modbus over RS-485 full duplex to communicate to an engine control system. See image for settings on ECS
I’m getting a response from the device using the specified Modbus addresses in the manual, but they don’t match up with the actual values at all, and they are all static values.Most of the values are temperatures that would change at least a degree every now and then but none of my readings change.
I’ve tweaked with the byte swapping settings to try to manipulate values, but the results are still random static numbers.If this is 4-wire 485, do I choose RS-422 as my physical standard? The RS-422 option was the only way I would get a response from the device at all and have my subnetwork light at least flash green.Are there any other settings I should look at to change?
I’ve attached my configuration and more pictures to give a better idea.Thanks for the assistance.
