3.5.3 Special Operational Scenarios - Inputs
There is only one way to permanently Arm an input point; remove all Scheduling and Automatic
control for the point and manually Arm it.
These are the ways to permanently Disarm an input point:
•
Manually Disable the point.
•
Assign an "Always" or 24/7 time code to the point in the Scheduler and remove all automatic
control.
•
Manually Disarm the point after removing all scheduled and automatic control for the point.
If a point subject to scheduled control needs to be Disarmed prior to the scheduled time, manually
Disarm it. If a point subject to scheduled control needs to delay entering the Armed mode, place
the point in Override mode. The point can be issued a Manual Arm command later.
3.5.4 Rules for Output State Changes
As with inputs, these are the ways to initiate operational state changes for outputs:
Scheduled - time codes defined in the plug-in. When a time code becomes active (Start Time) the
output is activated. When the time code expires (Stop Time) the input is deactivated. During the
intermediate time between start and stop, the scheduler will not automatically alter the state of an
output.
Manual - user action. Such action can only be initiated from the Workstation.
Automatic - NetLogic equation execution. After evaluating an equation, NetLogic may execute an
action which sends a command to the NION.
Scheduled, manual and automatic are all equivalent in priority. As each state change command is
received it is given priority over any previously received command.
These are the states for output points:
Output On
Output Off
Automatic Output On
Automatic Output Off
Momentary Output On
Momentary Output Off
As an output point transitions through any of these states the appropriate state change event is
broadcast on the network.
Output points can transition directly from one off-normal state to another without a return to
normal event between. Example: If a point is in an Automatic Output On state it can transition
directly to a Momentary Output On state.
A manually issued Momentary Output On is executed as a Momentary Output On followed by a
Momentary Output Off. The pulse time is dictated by the Delay field on the I/O Configuration
form of the plug-in.
