When using the FIN3 protocol, version of the driver and defining address for TF register (Timer Completion Flag) to be of type “Digital”, I get a compiler error, “Bad IO Device variable”. This compiler error did not occur in older version of the driver.

The data type for Timer completion flag have been changed from “Digital” in the old driver version to a “Byte” in the new driver version Timer completion flag is represented as a byte in both OMRON CV and CS
PLCs and as such the Fins driver have been modify to read a byte rather than a bit.
