phlorek Posted May 13, 2020 Report Share Posted May 13, 2020 Hello, I'm a complete beginner to the topic so I apologise in advance if my terminology is lacking. I'm trying to create a simple application using an Unitronics HMI+PLC SM70-J-T20. I have created necessary logic for the program to work, but now I'm at the point of trying to send signals initialized within the program to a Moxa E1212 I/O module. From what I have gathered, there is no way of operating on the I/O directly through VisiLogic and the only way of communicating with Moxa is through MODBUS IP and addressing of the I/O. I have set IP of the I/O module as well as the HMI according with my local network based of my computer ethernet card. Unfortunately the SB 150 stays at the value of 0. It may be a total non-sense, but I think this means devices are not connecting. I have attached a snipet of the code that is supposed to connect them to each other. Is my syntax or/and understanding of the topic correct? Thank you so much for any input! snipet.vlp Quote Link to comment Share on other sites More sharing options...
