smarius76 Posted April 21, 2023 Report Posted April 21, 2023 Hi I try to make a communication between CJ2M (with SCU 32), as master, and two EasyLogic PM2200, as slaves, through a modbus RTU communication. I use function block specified in this library https://www.myomron.com/index.php?article=1245&action=kb (I Use MRTU_SCU_Master sample) but no response fom the slave. On Modbus Error code (from function block) appear code 8303 hex. What I am doing wrong. Can somebody help me? Thank you Quote
