Hello,
These days I'm having a problem using modbus to reading pressure data from TROX terminal unit. It is kinda simple idea - 7 slaves (TROX units) and V700 is master and gets all the data. But as I'm conneting modbus though all of them I get error that there is no connection between TROX units. Slaves ID are set properly, cable polarity have been checked too. Maybe there are some other problems that I don't know? Thank you kindly for answers.
