Figure 2.2.1: Logic of DGF status
The transition from one status to another occurs via commands sent to the card by the
DGF serial line, keypad, serial line of the drive, field bus, or digital input.
SINCRO: The DGF moves into this state only after a reset of the system.
In this phase the following operations are executed:
- initialization of hardware devices
- synchronization with the drive
- initialization of DBASE data from ARCHIVE DBASE
At the end of these operations the DGF goes automatically
into IDLE.
IDLE: The DGF can move into this state from any other one. IDLE is
the programming status. In this state, the following commands
can be executed:
- configuration of DPRAM automatic structures
- configuration of system parameters
- loading and updating of ARCHIVE DBASE areas
