MVP 2021 Joe Tauser Posted July 30, 2017 MVP 2021 Report Share Posted July 30, 2017 Yes. If you haven't already, download the U90 software and search the Help for "Modbus". One thing to consider - you will need to add the RS232/485 COM port module. The added cost of this module puts the total cost of the Jazz close to the price of a V130, which has a COM port built in and a lot more power than a Jazz. Joe T.

MVP 2021 Joe Tauser Posted August 2, 2017 MVP 2021 Report Share Posted August 2, 2017 Modbus holding registers are indicated by the prefix "4", but it is not used in the actual address. Store "111" into SI 142. Joe T. Quote Link to comment Share on other sites More sharing options...
