M204.0507 Invalid device selection character: x'hexValue'
This message is issued during initialization (IODEV processing) when the low-order half of the DVADD parameter does not specify the hexadecimal equivalent of a valid device polling address. Model 204 continues without this terminal. The hexadecimal appendage contains the invalid device polling address.
System manager response: Correct the DVADD parameter in the CCAIN input, and rerun Model 204.
Operator response: Notify the system manager.
