Posted 9 Dec 2016 Hello everyone, in my project I have to connect CJ2M-CPU34 with CJ1W-SCU31-V1 module to external device (see technical specifications in attachment). The CJ2M should read and write a few values from the external device. Unfortunately, I dont have a chance to try this communication before, just during system start. I never make any project on Modbus. Anyone can send me a program to communicate with this device, according to documentation in attachment? 38RBS_Modbus_1.pdf Modbus_2.pdf Share this post Link to post Share on other sites
