About firmware upgrades
Each ProcessLogix software version release includes files for updating the
firmware version in system hardware components to levels compatible
with the given release. This means you must use the ProcessLogix
Engineering Tools utility called Network Tools (NTOOLS) to check
that the firmware versions for the hardware in your network are
compatible and to upgrade them as required before initiating control
operations.
If this is the first time you have used Network Tools on this PC, refer
to Using Network Tools on page 5-14.
After a ProcessLogix Server upgrade, you must always upgrade the
firmware in the Control Processor module (1757-PLX52) and the Serial
Interface module (TC-MUX021) to match the current ProcessLogix
software version before you can download a control strategy.
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.
IMPORTANT
Be aware that firmware versions for these modules are
not qualified for backward compatibility either. For
example, if you try to use a 1757-PLX52 with a
firmware version that is compatible with R320.0 with
a Server running software version R300.1, the control
and operation of the system is not guaranteed.
