Controllino and DELTA 103WQ

Post by wplarthshkr » Thu Jun 06, 2019 9:21 pm

Hi, I want to make a project with controllino MAxi and a HMI screen in Delta 103WQ. I'm using modbus, but I cant communicate both devices. I use the example code to HMI RS485 interface but it doesnt work. Can anyone help me with this problem?

Hi,

in general, we strongly recommend following procedure to bring your Modbus setup into live:
  • Try to run the setup with a PC as the Modbus Master.
  • There exists some free to use Modbus Master applications for PC.
  • In this way you can be really sure that you have correct cabling, you have correctly setup addresses of the slave devices and you are using correct Register numbers.
  • Once it is working, then you can start the integration with CONTROLLINO.
Good luck!
