Read/Write Mixed Data function

[Flex727]

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.

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.

Thank you, Ofir!

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)
