I'm trying to build a project on PanelView C600 Touch Screen HMI. communicating it using Modbus with a pc via serial link. the pc act as a Modbus slave. after configuring both the slave simulating program and the HMI communication settings, I add a pushbutton command to the screen and linked it to a certain signal. when I run the project and press that command, the value of the register changed on the pc, but I got an error on the HMI saying "Write Error for Alias l63, Controller PLC-1, Address is 00001, Communication Flag is 0". looking at the messages, it seems like the pc receiving the message and send its response to HMI; same thing happened with reading and writing all other data types.
Hope any one can help solving this issue.
