Isakovic Posted May 28, 2018 Report Share Posted May 28, 2018 For Unitronics side you need Modbus config block and scan block in your ladder. And also Modbus address space to find what you want to read, you can find all of this in help files and examples. You can also use system operands for Ethernet (SB, SI and SDW) for troubleshoting, To see if Fatek's messages are getting through. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted May 28, 2018 MVP 2023 Report Share Posted May 28, 2018 There are also example projects that came with your VisiLogic installation that will help you. Quote Link to comment Share on other sites More sharing options...
Kikis Posted May 29, 2018 Report Share Posted May 29, 2018 If you have a look on the examples included within Visilogic, it will be easy to set up your V700 as a modbus TCP slave. Attached is a photo of slave addressing table for Unitronics Vision enhanced PLC series. Quote Link to comment Share on other sites More sharing options...
