Rockwell Automation 1757-SWKIT3200 ProcessLogix R320.0 Installation and Upgrade Guide - Manual (Page 236)

Publication 1757-IN032B-EN-P - April 2001
6-20 New Functions and Features
The following will not cause a failover if the ProcessLogix servers are
synchronized:
•
The CNet cable is disconnected.
•
A PLX52 controller is disconnected or fails.
Station Object Model Extensions
The Station Object Model has been enhanced in Station R320.2 to
include new events OnConnect and OnDisconnect. These provide a
way of receiving notification when Station connects (or disconnects)
to a server. In the past some customers have used the OnAppStartup
event, but this event is only fired by Station when the program is first
started.
RSLinx 2.2 Service Pack 1
The RSLinx 2.2 Service Pack 1 addresses several anomalies reported in
RSLinx 2.10.118 along with new functionality identified below.
Although this service pack requires that the Base Release of RSLinx
version 2.20.107 (or later) to have been previously installed, the
ProcessLogix installation automatically installs RSLinx version 2.20.107
(if necessary) prior to applying the service pack.
All Hot Fixes and Service Pack updates since RSLinx version
2.10.118.00, Driver revision 2.012 drv have been incorporated. This
includes performance enhancements specific to ControlLogix, which
requires an update to the Logix5550 firmware.
