Transition from LOCKED State to Exclusive System Operation
Prerequisite:
ƒ Processor module state: LOCKED
The system operation is started if one of the following events occur:
ƒ The position of the mode switch changes from Init to Run or Stop
ƒ The user sends a command from within the PADT.
i
The controller might not restart automatically after interrupting the operating voltage
If the mode switch of one processor module is in the Init position and this processor module
is accidentally the first to be started when the operating voltage is reconnected, it remains
in the LOCKED state and does not adopt system operation.
If an Autostart is required after interrupting the operating voltage, the mode switches on all
the processor modules must be set to Run!
i
Turn the mode switch quickly from Init to Run to prevent the processor module from
entering the STOP state.
Switch Position: Stop
Only operative if the processor module is not operating redundantly.
Effect:
ƒ Non-redundant operation:
The processor module disables any pre-configured Autostart and remains in STOP.
ƒ
Redundant operation:
The processor module adopts the same operating state as the other processor modules.
i
The controller might not restart automatically after interrupting the operating voltage
If the mode switch of one processor module is in the Stop position and this processor
module is accidentally the first to be started when the operating voltage is reconnected, it
remains in the STOP state. Consequentially, also the remaining processor modules cannot
start.
If an Autostart is required after interrupting the operating voltage, the mode switches on all
the processor modules must be set to Run!
Switch Position: Run
To set for safety-related operation!
Effect:
ƒ Non-redundant operation:
The processor module starts the user programs if Autostart is activated.
ƒ Redundant operation:
The processor module adopts the same operating state as the other processor modules.
