Appendix E
History of Changes
This appendix summarizes the revisions to this manual. Reference this appendix
if you need information to determine what changes have been made across
multiple revisions. This can be especially useful if you are deciding to upgrade
your hardware or software based on information added with previous revisions of
this manual.
1769-UM006D-EN-P,
May 2011
• Changed the hysteresis detection and configuration section to indicate
that the Ctr[n].CurrentRate is reported as zero if the change in counts over
the update time cycle is equal to or less than the minimum number of
programmed counts.
• Added that the individual counter reset function for the 1769-HSC/B
module applies to only CompactLogix controllers and not MicroLogix
controllers.
• Changed hex equivalent values for general common hardware errors.
• Changed the input file update time to 500 ìs, max.
1769-UM006C-EN-P,
November 2010
Updated the counter reset in the configuration array for bits 12…15. The
individual counter reset functionality for the 1769-HSC series B module is
reverse logic with a 0 = enabled and a 1 = disabled for RSLogix 5000 software.
The firmware change applies to only the 1769-HSC series B module.
