The following table describes the attributes used by the Plant Control modules:

Table 1. Plant Control Attributes

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

1 C - Configuration Mode Only, G - Default Element (Generated State, if applicable), SC - Simulation and Commissioning Modes Only, V - Calculated Value (Outputs)
