Configuring the Switching Mechanism
GPI Input Control
Chapter 3: Configuration and Operation
Three factors control the output channels on the ACO6800+:
• GPI control
• Alarm severity levels for each input channel
• Parameters that can be manually switched in CCS Navigator or at the card
edge
Use the following parameters in the Switch Settings group of parameters to
define the switch priority levels:
• Group A or Group B Switch High Priority (the default setting is GPI Input)
• Group A or Group B Switch Medium Priority (the default setting is Manual)
• Group A or Group B Switch Low Priority (the default setting is Alarms)
A high priority event overrides a medium priority event, which overrides a low
priority event. The three options are mutually exclusive.
As an example, the current settings might start out in these default values:
• Group A Switch High Priority: GPI Input
• Group A Switch Medium Priority: Manual
• Group A Switch Low Priority: Alarms
By changing the Group A Switch Low Priority setting to GPI Input, the module
automatically changes the Group A Switch High Priority setting to Alarms. This
new setting is exclusive, and will not conflict with the Medium and Low settings.
Table 3-3 indicates what happens when a GPI Input is activated—for example,
pressing a button on a panel—when the switching is not triggered by other higher
priority events than GPI Input.
