I have two NCD enterprise 2ch 4-20ma current loop sensors turned on near the NCD enterprise Modbus RTU modem (white model). I am trying to poll the registers of the modem with my Modbus master device. The master device is set to 9600, 8N1, and attached is my Modbus master table. I read in the documentation I can poll 50 registers and always get the correct packet back, but my master continues to just time out. My request delay is 250ms, my response timeout is 1000ms.
How do I need to setup my table to poll registers from the NCD device?
