Parameter Assignment
using the PG Screen Form
With the PG system software, screen forms are available for assigning
parameters in DX 0 for the CPU 948. The PG software automatically
generates data block DX 0 according to the default parameters (values
in bold face)and parameters you have specified. To assign parameters
to DX 0, two screen forms are required.
How to select and complete the PG screen forms is explained in your
STEP 5 manual.
Structure of the screen forms Two screen forms are required for completing parameter assignment
to DX 0:
The first screen form (Fig. 7-2) contains the parameter groups
- Interruptability,
- Restart after power up,
- Warm restart procedure,
- Number of timer cells,
- Cycle time monitoring,
- Synchronize multiprocessor restart,
- Block transfer of the IPC flags.
