MVP 2021 Flex727 Posted October 8, 2015 MVP 2021 Report Share Posted October 8, 2015 I notice that the Unitronics MODBUS communications function, "Read/Write Mixed Data", crashes the communications if I try to use it between a Vision controller and a UniStream controller. This is a VERY handy function and I'm wondering if there are any plans to make the UniStream compatible with this function. Quote Link to comment Share on other sites More sharing options...
Ofir Posted October 11, 2015 Report Share Posted October 11, 2015 Hi, The memory structure of the Vision and UniStream is different and this is why this command is not supported. Anyway I will pass this request to our R&D for review. Quote Link to comment Share on other sites More sharing options...

hotwires Posted November 26, 2016 Report Share Posted November 26, 2016 I second this motion, the mixed R/W data function greatly simplifies Modbus i/o exchange in vision units. I'm trying to use a unistream in place of a V430 as a MODBUS master and having diffuculty in implementation (far beyond the absence of R/W mixed data) Quote Link to comment Share on other sites More sharing options...
