Hello,
This is the errors I am getting below for the symbol configuration.
How to fix this (Waintek cmt2078x panel )

The P2CDS-622 currently does not support symbol configuration.
I'm not familiar with using these HMI's but after a little researching it looks like you can talk to these over modbus which the P2CDS-622 supports.
If you have more questions feel free to ask to see if we can offer some help.
And how can I solve this problem? Can you tell me?
Most HMI's in the automation field support more than 1 way to talk to them. The modbus protocol is one of the easiest and most common protocols supported.
The Weintek HMI can be setup as a Modbus server.

The P2CDS-622 will be the modbus client(master) that can talk to the HMI server.
Here's a reference for setting up the modbus client device.

Well that's a bummer, symbol config gives you full symbolic support in EBPro and none of the Modbus hassles.
