Justas Grinaveckis Posted February 28, 2017 Report Share Posted February 28, 2017 Hi, I'm having hard time displaying data on V700 PLC. After MODBUS config and reading holding registers HMI still shows 0. Do I need to write data to data table and only then display on HMI? Data has to be read from MIO 12-V I/O module. Network ID matches, start of vector links to hmi variable. What could be done or I did wrong? Thanks. I'm attaching vlp file here Quote Link to comment Share on other sites More sharing options...
