The following table describes the attributes used by the Plant Control modules:
|
Name |
Type 1 |
Description |
Default Value |
|---|---|---|---|
|
Alarm |
Indicates the status of the primary device condition. |
Normal |
|
|
Alarm Delay |
Indicates the value in seconds to wait for inputs to clear before generating an alarm. |
30 Seconds |
|
|
BLRX-OUTSTATE or CHX-OUTSTATE (Device OnOff) |
G |
Provides a Binary output to the primary controlled device. This attribute is used to start the pump or boiler, for example. |
Off |
|
Command |
Starts the interlock and the device when in a Mode of Control. When in a Mode of Interlock Only, this input starts the interlock. |
False |
|
|
Interlock Command |
Provides a Binary output for the interlock device. This attribute is used to open the isolation valve or circulation pump, for example. |
Off |
|
|
Interlock Off Delay |
Indicates the value in seconds to wait in Off Mode before stopping the interlock device. |
300 Seconds |
|
|
Interlock Status |
Provides a Binary Input from an optional interlock device (isolation valve status). This attribute is used to prevent the primary device from starting unless status is On when connected. |
On |
|
|
Maintenance Switch |
Provides a Binary Input to disable or enable the controlled device. |
Enable |
|
|
Mode |
Determines mode of the module. |
Off Set Name: Plant Control |
|
|
On Delay |
Indicates the time in seconds to wait before turning on the Command output in Control Mode. This attribute is used to allow interlocked devices to activate before starting the primary device. |
20 Seconds |
|
|
Output (Float) |
V |
Provides an Analog output for the primary device. This attribute is used to modulate the boiler burner or load chiller, for example. |
0.0% |
|
Percent Cmd |
Provides an Analog Value input to determine the percent operating level of the controlled device. |
0.0% |
|
|
Percent Limit |
Indicates the maximum analog output value for the controlled device. This attribute is used to limit the operation of the analog device. |
100% |
|
|
Ramp Time |
Indicates the time in minutes that the ramp block takes to change from 0 to 100% output. |
20 Minutes |
|
|
Rotate Enable |
Provides a Binary output that indicates if the current device is allowed to run. |
False |
|
|
Safety |
Provides a Binary Input from an additional optional safety device (flow switch). This attribute is used to prevent the primary device from starting unless safety is On when connected. |
On |
