Summary:
When using the FIN3 protocol, version 1.3.6.0 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.
 

Solution:
The data type for Timer completion flag have been changed from “Digital” in the old driver version 1.3.1.55 to a “Byte” in the new driver version 1.3.6.0. 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.
