Start-up
Refer to relevant document for information on:
• Firmware download
• Controller IP address
• Downloading application
• Updating firmware
Start-up in Redundant Configuration (CEX Bus Considerations)
The redundant configuration using CEX bus and CEX modules is supported along
with the processor modules PM858, PM861, PM862, PM864, PM865, PM866,
PM867 and PM891.
At start-up, some things regarding the CEX bus and CEX modules have to be
considered when starting up a redundant AC 800M system:
• Without using BC810 units:
CEX-BUS Provides extension of on-board communication ports.
Valid for PM858/PM861/PM862/PM864/PM865/PM866/PM867
RCU Link Connector Provides information and data transfer between Primary
and Backup CPU in redundant configuration.
Valid for PM891
RCU Data Link
Connector
Provides transfer of data required to keep the backup
CPU synchronized with the primary CPU.
RCU Control Link
Connector
Provides role selection and CPU identity assignment.
(1) Electrical ModuleBus not valid for PM891.

– At least one CEX module must be inserted, if there are base plates without
inserted modules in other positions.
– After having rebuilt the hardware on the CEX bus, that is, after removing
or adding a number of base plates (equipped with CEX modules or not)
the upper CPU (the CPU connected to the part of the RCU Link cable that
is marked “UPPER”) must be started as the primary CPU the first time.
Start Modes
Warm Start
Application-controlling tasks are initiated. Variable values are initialized unless
marked Retain or Cold retain.
To initiate a warm restart, disconnect the power supply for a few seconds.
Following a power failure, the warm restart function will be automatically initiated
on power restoration.
Cold Restart
The application program restarts. Variable values are initialized unless marked Cold
retain.
To initiate a cold restart, the Controller must be restarted by briefly pressing
the INIT push button (less than 2.5 seconds).
Cold Restart in Redundant Configuration
To restart CPUs running in redundant configuration:
1. Perform a Controller Reset of the backup CPU (see below). The system will go
into single CPU state.
2. Wait a few seconds and then restart the Primary CPU by pressing the INIT
push button less than 2.5 seconds.
After a power fail, instead of doing a warm restart of the application SIL3
applications are restarted using cold retain marked values saved in the controller
periodically with a cycle time set by the user.
Section 4 Operation Automatic Switch-Over to Backup CPU
3BSE036351-600 A 193
3. The system will be upgraded to synchronized CPU state once again.
Controller Reset
The system stops. The application program and variables are erased.
To initiate Controller Reset, press and hold the Controller INIT push button (more
than three seconds) until the Run LED begins to flash. A Controller Reset must be
performed if the system is in an undefined position and consequently unavailable to
the user.
Controller Reset in Redundant Configuration
Follow the steps below to perform a Controller Reset in redundant configuration:
1. Perform a Controller Reset of the backup CPU. The system will go single CPU
state.
2. Wait a few seconds and then perform a Controller Reset on the Primary CPU.
Automatic Switch-Over to Backup CPU
In a redundant configuration an automatic switch-over from the Primary CPU to the
Backup CPU occurs in the following situations, provided they are in synchronized
state (DUAL LED is lit):
• Memory error in the Primary CPU.
• Other HW-error in the Primary CPU, which causes CPU crash.
• Severe communication errors on the Control network, that is, loss of both
network ports in the Primary CPU.
• Severe communication errors on the ModuleBus (if ModuleBus is part of the
HW configuration) that is, loss of clusters in the Primary CPU.
Note that a Backup CPU with severe communication errors on the ModuleBus
will be rejected (if ModuleBus is part of the HW configuration) and
synchronized state will never be reached as long as error remains. | 通用电气 745-W2-P5-G5-HI-R-E 安装在综合保护继电器 GE | | | | |
