I've been trying to display any modbus register from the Nexus 1250 RTU to an intouch HMI. I tried with the modicom IOServer but i don't quite know how to create a workig topic in order to call it from a variable created on the window maker. Has any one of you created an access to any register on the Nexus 1250, so you can create an HMI to show the readings? What have you used?

 

Hi. Please get our Nexus 1250 Modbus register map from our website. http://www.electroind.com/pdf/NxModbusE107708118.pdf

Take note of the parameters that you want to display from your HMI and poll that specific register from the Nexus. Thanks and let me know how it goes.
