Note that the first three bytes are added from the last request and after that the read-in is following. It really looks like that there is really one byte missing between "08" and "01". Note: I chose to check the second message you posted, just simply because it's shorter.Īd "failed to read: CRC Error in received frame: 10 bytes: 1e 03 08 01 00 01 00 01 08 98": (Precondition see: ) I also attached (see txt file) the output I got with that very bringup test. and more clear error message when all bytes are not received with Modbus/RTU. The openHAB modbus binding uses data frame entity addresses when. I modified it, to fit the second request sent out by your openHAB "Last request: 1e 03 03 e9 00 04 97 d6", you can find that version at New release openhab/openhab-distro version 3.1.0.M4 openHAB 3.1.0. Modbus RTU is the easy-to-implement Master/Slave communications protocol built by.
