Section 2.6.5 Extension with Redundant Processor Module

2.6.5 Extension with Redundant Processor Module
You can install an additional processor module at any time for redundancy.
Normally, a dedicated slot in the controller subrack, module position 2, should be spare.
The processor modules must be coordinated. Do the full identification by reading a label on the
printed circuit boards. Then shut down the system and withdraw the existing processor module,
if this information is not otherwise noted. The additional processor module must have the same
or higher revision number. The document Release Notes included in the Delivery Binder states
which processor modules can work in a redundant pair and which can not. For example, you can
not mix 8 and 16 Mbyte versions.
Despite the option to install an additional processor module on-line, it is recommended that you
do the work keeping hazard to a minimum. The best way to minimize hazard is to shut down the
controller. Reflect on these points:
•
Process safety
•
Need to test the newly installed equipment
•
Need to test earlier logic and connectors not utilized in the existing equipment.
Note possible years of operation and environmental influence.
Power supply redundancy is sometimes introduced at the same time. In that case, system shut-
down and power supply disconnection become compulsory.
Extension On-line
1.
Check module identities.
2.
Check module position 2 (item designation 108, see
) for
visible damage, dust, etc.
3.
Set start mode selector on the new processor module in STOP position.
CAUTION
Do not forget the general rule: Reflect on the danger of ESD. Use the
grounded wristband when handling circuit boards.
4.
Insert the new module in position 2.
Check the display on the module front, which indicates -3 (STOPPED) after a few
seconds.
5.
Set the start mode selector on the new processor module in the same position as the
existing processor module.
6.
Push the ENTER button on the new module.
Check the display. A correct installation gives the following indications in sequence:
a.
b2 (UPGRADING), b1 STANDBY) after
<
90 sec.
b.
LEDs DUAL on both processor modules light up.
7.
It is recommended that you perform a function test. Manual changeover is described in
