The following table describes the attributes used by these modules.

Table 1. Dual Pump Sequencer Attributes

Name

Type 1

Description

Default Value

Device 1 Enable   Establishes the enable status of the sequencer device outputs. A value of FALSE takes the associated device out of service. False
Device 2 Enable   Establishes the enable status of the sequencer device outputs. A value of FALSE takes the associated device out of service. False
Device 1 OnOff V Contains the output value for the corresponding device. Off
Device 2 OnOff V Contains the output value for the corresponding device. Off
Device 1 Runtime   Represents the ranking of each device. This value establishes the order by which the device outputs are activated. 0.0 hours
Device 2 Runtime   Represents the ranking of each device. This value establishes the order by which the device outputs are activated. 0.0 hours
Instant Shutdown   Forces all outputs inactive when it is TRUE. When it is FALSE, the module monitors the input and stages the outputs. When this value transitions from FALSE to TRUE, all of the outputs are deactivated instantly (ignoring any Minimum On Timers and the Interstage Off Timer.) False
Interstage Off Delay Time   Defines the minimum time interval that must elapse between the sequential deactivation of multiple Sequencer stages unless the Instant Shutdown value is TRUE or the primitive is disabled. 5.0 seconds
Interstage On Delay Time   Defines the minimum time interval that must elapse between the sequential activation of multiple Sequencer stages. 5.0 seconds
Min Off Time   Indicates the minimum time that an output must remain off before it can be reactivated to an on condition following deactivation. As such, a separate timer is established for each device output upon being deactivated. Until the time interval expires, the output is blocked from being reactivated unless Rotate Now has transitioned from FALSE to TRUE. 30.0 seconds
Min On Time   Indicates minimum time interval that an output must remain on before it can be deactivated to an off condition following activation. As such, a separate timer is established for each device output upon being activated. Until the time interval expires, the output is blocked from being deactivated unless the Instant Shutdown value is TRUE, the module is disabled or Rotate Now has transitioned from FALSE to TRUE. 30.0 seconds
Pump OnOff G Represents enumeration value that is the control signal input to this module. Off
Rotate Now   Activates by rising edge. It retains a value of TRUE until it is written back to FALSE. Writing this attribute to TRUE causes an immediate rotation based on the current ranks. False
1 C - Configuration Mode Only, G - Default Element (Generated State, if applicable), SC - Simulation and Commissioning Modes Only, V - Calculated Value (Outputs)
