Martin1 Posted July 25, 2017 Report Share Posted July 25, 2017 Hi, I have a v570 that is communicating with a Wonderware Intouch SCADA computer. I want to be able to read/write MF tags to and from both devices. When I write a value of 1.23 from SCADA, the v570 reads it back as 4.066596E+29. This was tested using MF0 using value "416385 F" in Intouch. Is there a way of displaying the MF value directly? Link to comment Share on other sites More sharing options...
Henny Posted July 25, 2017 Report Share Posted July 25, 2017 Hello Martin Im not a intouch expert but it sounds to me that the communication between the V570 and Intoch is established and only the data presentation is wrong? The link leeds to a wonderware intoch manual about modbus communication between a modicon plc and intoch. Take a look at page 37 where you have an option "Use data concept Structures (Reals). Perhaps this Will help you any further? https://insource.mindtouch.us/@api/deki/files/1260/DASMBTCP_3.0.pdf?revision=2 kind regards henny Link to comment Share on other sites More sharing options...
