Hello Carlos,
You may refer to the help documentation for a detailed explanation of the icon meanings.
I/O monitor
As this is an input channel, it is indicated in green.
red triangle with exclamation mark is ‘Additional identifier to identify I/O mappings where the assigned variable does not exist on the PLC.’.
Thank you Mrs Eun Im
How can i solve this?
I have two devices connected to my Panel PC 2100 via Modbus; I have no issues with one, but with the second, I cannot link data points to the channels. Process variable value is in error

Hello,
By reading the previously shared help link and screenshot, the variable “CommData1.ModbusTCP.Modu…” doesn’t exist on the PLC. Is the task CommData1 in the SW configuration of the PLC? Is the ModbusTCP.Modu… structure used somewhere in the code?
Your observation is correct; I found a post mentioning that this problem arises because the variable isn’t being used anywhere in the code, so the compiler ignores it. It was resolved by using the variable.
