Leer datos desde una hmi

Ignition
1

Hello, my name is Alejandro, and I need help with a Kinco MT4434TE screen and a Xinje TG765-MT-ET screen, both with Ethernet (Modbus TCP) connections. I'll try to be brief. The HMIs are working and connected to slave devices via Modbus RTU. What I need is to read the data from the slaves via Modbus TCP from the HMIs and send it to the Ignition SCADA system via Ethernet. Currently, the HMI is already connected to the SCADA system, but I can't read any variables.

Has anyone connected to a similar HMI and successfully read variables?

If I understand correctly your 2 HMIs are reading data via Modbus RTU and you need Ignition to read registers from the HMI via Modbus TCP? I don't know those HMIs but I'd assume you need to map the RTU data into a set of HMI tags or registers that then get mapped into the HMI's modbus table of registers (or they directly link to the RTU registers somehow). What have you tried so far? Can you give details and screenshots of your configs in the HMI and Ignition?

How is the hmi connected to Ignition?
