Panel is a EA1-T4CL mated to a C0-01DD2-D Click PLC on Port 2 at 38400, 8, odd, 1. Port 3 is connecting to a VFD. I have no problems sending strings to the VFD from the PLC. I want to send a user input from the HMI to the PLC to the VFD. How do I send a user input numeric display value to the PLC. I have no problems with discrete inputs or outputs but for some reason I just can't send a string. I have done a lot of HMI to PLC integration using other brands but this is stumping me. Can someone help please. Please post a example if possible.

I haven't tried to send ASCII from any HMI, but I see the full fledges CMORES have a "text entry " object available, and the CMORE Micros do not have that object available.

Ok, it really was simple :D
Just used a Single Copy. Tagged numeric entry on the Cmore panel as DS100and copied to DS200. Used Modbus to send DS200 to the VFD.
I was trying to use a Receive command from the Panel and got nowhere!!!!
