Bug 21103 - R registers must be assessable at bit level.

Comment:

Affected files:

  • Drv_ver.h

NOTES added later:

  • After the MelscNet.dbf file was modified to allow BIT access to the R registers in the Mitsubishi Q series PLCs, it was found that when performing bit WRITEs to a R register, the driver could only write to the first bit. This is not a comlete fix and should not be used.
