Model PDP DPU Installation, Preparation and Adjustment
7-4
The following sections describe the expected entries and automatic defaults
on Interaction Page 9.
Startup
The startup? prompt appears when manual intervention is required
following a cold startup or fatal alarm. (For example, an I/O module fails
and is not configured as an alarm-only module.) After Interaction Page 9 is
reviewed and configured, enter Y in the entry field to place the DPU into
operation. Ensure that the keyswitch is in the Online (Run or Locked)
position.
Backup Option Field
DPUs can be paired in a redundant configuration as described in Chapter 5.
To configure the backup option, enter Y in the Backup field.
Stat Page Field
This field determines what is shown on Interaction Page 8. The default for
this field, 10, places the I/O status and event queue display on page 8.
During configuration this field may be changed to 11, DPU Serial Links
Status; 12, DPU Bus Performance Statistics; or 13, High Speed Digital I/O
Tabular Display.
DIO Inventory Field
The Digital Input/Output (DIO) Inventory can accept 30 entries in the ranges
1 to 15 and 17 to 31.
Enter I or O to indicate input/output modules.
Examples:
1
I
2
O
Append an A to indicate that loss or failure of one or more of these modules
is not a fatal alarm, as would be the default. (Any fatal alarm forces the DPU
to Offline mode.)
Examples:
1
I
2
O
3
IA
4
OA
