Enhanced Micro TDC 3000 User’s Manual 5-8 9/95
5.2.3
When the APM data has been restored, the modules may still be in an IDLE state. Check
this by calling up the UCN Status display. You can call up the UCN Status display in one
of two ways:
• On the System Status display, select the Process Network Status 1 target.
• On the Gateways and Interfaces Status display, select node 1, then select NTWK
STATUS.
If the status is IDLE—
Select the 03 APM target.
Select the APM SYS COMMANDS target.
Select the STARTUP target.
Select ENTER. The status should
change to OK. If there is a redundant
PMM, its status should be BACKUP.
Detailed instructions for loading programs, and saving and restoring data for UCN devices
are provided in Section 18 of the Process Operations Manual.
5.2.3 Loading the History Module
The History Module is configured, loaded, and initialized at the factory. Thereafter, it is
able to load itself (to “autoboot”) after its operation is interrupted, provided that it had not
had a failure from which it cannot recover. For example, if the ac power supply to the HM
is interrupted and then returns, the HM normally autoboots, and returns to normal
operation, showing a status of OK on the History Modules Status display.
If, for some reason, you do not want the HM to autoboot, on the History Modules Status
display, select 6 (the HM node number), select ENABLE LD/DUMP, and select DISABLE.
This disables HM autobooting until the Enable Load/Dump status is changed back to
ENABLE. If you need to reload the HM, refer to the System Startup Guide.
5.3 SYSTEM OPERATION
At this point, the system should be up with all modules running. You should remove any
cartridge disks from the drives. The System Overview in the System Summary binder
provides a description of overall system operations, including descriptions of the use of
standard and custom (graphic or schematic) displays and other human-interface features to
monitor, control, and manage a process. If you are new to LCN-based TDC 3000
X
Systems, we recommend that you read the following sections in the System Overview:
• Section 5—Man/Machine Interface
• Section 6—System Operation
• Section 8—System Maintenance
