MVP 2023 Joe Tauser Posted September 5, 2013 MVP 2023 Report Share Posted September 5, 2013 The PLC appears to be configured correctly, although the name is a little long. What you've done is set the PLC up as a Modbus TCP slave. 1. What is the IP address you assigned? 2. What are parameters you used in the SOCK INIT block for Socket two? 3. What have you done with KepServer so far, and what errors are you getting? 4. Where did you get your copy of KepServer? Joe T. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted September 5, 2013 MVP 2023 Report Share Posted September 5, 2013 I did a little more digging on KepServer - Here's their Help on configuring it for Modbus TCP: http://www.kepware.com/Support_Center/SupportDocuments/Help/modbus_ethernet.pdf From the Unitronics side, read the Help on Modbus Slave Addressing - under the Search tab search for "Modbus" and choose topic 2 - "Slave Address Tables". Click on the link that says "Enhanced Vision Series" to show you what Modbus addresses correspond to which Unitronics addresses. Joe T.

kill_bill1 Posted September 6, 2013 Author Report Share Posted September 6, 2013 Hello! I made a screensoot from my settings: I wanted to try to read an input from the plc. Kepserver error message: Device 'Channel1.2000926907' is not responding. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted September 8, 2013 MVP 2023 Report Share Posted September 8, 2013 Your last dialog box for tag "prb" - what is the address in the PLC you are trying to read? Joe T. Quote Link to comment Share on other sites More sharing options...
kill_bill1 Posted September 16, 2013 Author Report Share Posted September 16, 2013 I tried to read the I2 input from the PLC. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted September 18, 2013 MVP 2023 Report Share Posted September 18, 2013 Look at Visilogic Help topic "Modbus Slave" and then "slave addressing" for the Slave Addresses of Enhanced Vision Controllers. It shows the "I" coils starting at address 6000h, so I2 would be 6002h. This translates to 24578 decimal. Try putting this address into the tag definition for prb and see what happens.
