dylan Posted April 15, 2014 Report Share Posted April 15, 2014 Hello can anybody help me . I'm trying to set up comms between citect 7.3 and a Unitronics 570. Do i have to run it between UniOPC and the HMI or can i connect direct..also what address would you label MI 2 for example when compared to MB 2.. I have looked at a great video file on the forum already,but im still getting an error on the Scada. i can send a copy of my program if it helps?? dylan Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted April 16, 2014 MVP 2023 Report Share Posted April 16, 2014 Do you have the Modbus driver for Citect? You can set the V570 up as a Modbus slave pretty easily and directly connect it. Joe T. Quote Link to comment Share on other sites More sharing options...
dylan Posted April 16, 2014 Author Report Share Posted April 16, 2014 Hi Joe i have been trying to connect using one of the modbus drivers that comes with citect 7.3 . im not sure if its compatible with windows 8? citect forum says it should be compatible, but it just wont connect. i think it must be something im not doing correctly. dylan Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted April 16, 2014 MVP 2023 Report Share Posted April 16, 2014 Upload your PLC program so we can see if you have the Modbus Slave configured correctly. Did you read the Help on Modbus slave addressing in Unitronics? Joe T. Quote Link to comment Share on other sites More sharing options...
