Upgrading
ProcessLogix Software on
a Redundant Server Pair
About Upgrading Software on the Server
ProcessLogix now automates most of the migration tasks from a previous
version of the system to the current version. The migration
enhancements support error handling and recovery from migration
problems.
While the ProcessLogix R320.0 software CD supports several platforms,
this procedure covers upgrading the ProcessLogix Software from R300.1
or R310.0 to R320.0 on the Server. In this case, the following components
are installed in succession once you start the installation setup.
•
RSLinx OEM 2.2
•
Engineering Tools
ATTENTION
!
Due to the changes in the communications protocol
between redundant servers in this release it is not
possible to synchronize a server loaded with this
version of ProcessLogix with a server loaded with an
earlier version of ProcessLogix (including R300.0,
R300.1 and R310.0). This means that redundant servers
should be upgraded to this release at the same time.
IMPORTANT
You must install the ProcessLogix Server on the same
partition on both the primary and backup servers and
that their directory structures match.
For example, if you install the ProcessLogix Server to
c:\honeywell\server on the primary server then it
should be installed to the same location on the backup
server.
Synchronization problems have been encountered by
customers installing the ProcessLogix Server to
c:\honeywell\server on the primary server and to
d:\honeywell\server on the backup server.
ATTENTION
!
Be certain that your process is off control before you
begin any upgrade procedure. This means the
1757-PLX52 should be in the Idle state.
