The result of a stop and its consequences are compatible for the two manual stop methods:
• Application program execution immediately stops.
• There is zero output to the process objects.
• Output relays are de-energized.
• There is no loss of process data (besides what is happening in the process in the
meantime).
• The system is ready for a restart. To perform a restart:
Set the start mode selector in 1 (AUTO) position and depress the ENTER button or
Command DICONFIG.
Automatic Stop
For the sake of completeness, the main reasons for an automatic stop are listed below:
• Loss of power supply
• Fault in power supply
• Fault in central processing unit and memory
• Other fatal error.
The result of an unintentional stop and its consequences are, from the viewpoint of design
philosophy, the same as for a safety shut-down (see above). However, when there is a fault
involved, other behavior must be taken into account.
After necessary measures, a restart can take place.
2.3.3 Peripheral Equipment
Shut-down of peripheral equipment, like a printer or local operator station MasterView 320, is
treated below from the viewpoint of power supply disconnection only.
Regardless of whether the peripheral equipment is powered common to the controller or from a
separate mains, you can shut down by disconnecting the mains whenever necessary. Any faults
or disturbances that may occur are local to the peripheral equipment only, for example a missing
printout.
You can restart by switching on the power supply whenever you like with respect to the
controller function. The peripheral equipment is self-initialized.
2.4 Start-up Procedures
Activities up through “ready for application program loading” are described in this section.
This includes power-up and the first definition/configuration of the system resources.
A visible result of the start-up procedures is that all red LEDs on module fronts are turned off
and all green LEDs are turned on.
