RES-406
Version 1
For controllers with software revision 100, 101 and 102 the configuration for the „TO“ bit can be set via
the ROPEX visualization software. As of software revision 103 the configuration for the „TO“ bit is set in
the PROFIBUS parameter data (or the DPV1 protocoll extension). A configuration with the ROPEX visual-
ization software is no more possible.
The limits of the tolerance band are adjustable to max. ±99K on controllers manufactured as of
February 2006 and supplied with GSD Version v1.5 (On older controllers the limits are adjustable to max.
±20K).
