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 3000X

Systems, we recommend that you read the following sections in the System Overview:
