There are six different 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.
Special Operational Scenerios - Outputs
There are two ways to permanently activate an output point:
1. Remove all Scheduling and Automatic control for the point and manually activate it (Manual Output On).
2. Assign an "Always" or 24/7 time code to the point in the Scheduler and remove all automatic control
There is only one way to permanently deactivate an output point; remove all Scheduling and Automatic control for
the point and manually deactivate it (Manual Output Off).
If a point subject to scheduled control needs to be activated prior to the scheduled time, issue a Manual Output
On command.
If a point subject to scheduled control needs to be deactivated prior to the scheduled time, issue a Manual Output
Off command.
Reset Conditions
When a soft node reset (workstation command) or a hard node reset (power down or reset button) occurs, all input
points are assumed to be in the Armed mode (see exception below). As part of the boot sequence, the scheduler
will immediately modify input modes and output states as needed. An event will be generated for every point on
the node.
For hard reset only, all outputs are deactivated in the hardware.
During a node reset, any input point that was in a Disabled mode at the time of the reset will remain in the Dis-
abled mode.
Memory Loss on the 16C48M
Because the 16C48M uses battery backed configuration memory, the following rules apply:
1. Each time the node is reset a memory check is performed to ensure database integrity. If at any time a
discrepancy is found, the memory will be formatted to a default state and a MEMORY LOSS event will be
broadcast on the network.
2. Default Memory Configuration - all input points are configured to four-state Normally Open contacts, with
0 second reporting delay. The input points will default to device type Digital Input with the event code
Addressable Input On/Off.
