Dionex Detector/Chromatography Module

In addition to the  General Device Commands, the following commands are available for control of DC operating functions (please note that the display Filter level determines which commands are displayed).

 

Property

Description

LowerDoor

Reports whether the compartment lower door is open or closed.

UpperDoor

Reports whether the compartment upper door is open or closed.

LowerLeakCondition

Reports whether the lower leak sensor is wet or dry.

UpperLeakCondition

Reports whether the upper leak sensor is wet or dry.

 

Suppressor Control Commands

The following commands are used for controlling a suppressor installed in a DC.

 

FlowStatus

Reports the status of the flow sensor (flow detected or flow not detected).

SuppressorName.Current

Reports the actual suppressor current.

SuppressorName.CurrentSet

Sets the current supplied to the suppressor and turns on the suppressor (SuppressorName.Mode=On).

SuppressorName.Mode

Turns the suppressor on and off.

SuppressorName.Type

Sets the installed Suppressor type.

SuppressorName.Voltage

Reports the suppressor voltage.

 

 

Notes on Suppressor Names

The following names are assigned to the suppressors by default:

Suppressor1: The first (or only) suppressor in the timebase

Suppressor2: The second suppressor in the timebase

 

Temperature Control Commands

The following commands are used for controlling the various DC temperature control zones (conductivity cell, compartment, column, and reaction coil heater).

 

Command/Property

Description

DeviceName AcquireExclusiveAccess

Gives exclusive access of the temperature zone to the current timebase. Exclusive access commands allow two timebases to share the same DC temperature zone.

DeviceName ReleaseExclusiveAccess

Takes exclusive access of the temperature zone away from the current timebase, to allow another timebase to acquire exclusive access.

DeviceName Mode

Selects whether the temperature zone is on or off.

DeviceName Status

Reports whether the temperature of the zone is under the set temperature, at the set temperature, or over the set temperature.

DeviceName TemperatureActual

Reports the actual temperature.

DeviceName TemperatureSet

Sets the temperature of the temperature zone.

DeviceName TemperatureState

Reports the state of the temperature zone (Ready or NotReady).

 

 

Notes on Temperature Control Device Names:

The following names are assigned to the temperature control devices by default:

Compartment_TC: The DC upper compartment

Column_TC: The DC lower (column) compartment

ReactionCoilHeater: The reaction coil heater

 

Injection Valve Control Commands

The following commands are used for controlling the high-pressure injection valves installed in the DC.

 

Command/Property

Description

ValveName.State

Indicates (and can set) the valve position (Load or Inject).

ValveName.LoadPosition

Switches the valve to the Load position.

ValveName.InjectPosition

Switches the valve to the Inject position.

Valve1Button

Reports whether manual control of the VALVE 1 button is enabled or disabled.

Valve2Button

Reports whether manual control of the VALVE 2 button is enabled or disabled.

Notes on Injection Valve Names

The following names are assigned to the injection valves by default:

InjectValve_1: The first (or only) injection valve in the timebase

InjectValve_2: The second injection valve in the timebase

 

 Notes:

When the VALVE 1 or VALVE 2 button is enabled in Chromeleon, pressing the button triggers the injection valve. When a VALVE button is enabled at the same time that a remote inject device is configured in the same timebase as the DC, pressing the button instructs the program to automatically continue collecting data after executing the inject command.

When an ICS-5000 IC Cube is installed, the VALVE 1 and VALVE 2 buttons are automatically linked to the injection valves in the IC Cube, not the analytical injection valves.

High-Pressure Valve Control Commands

The following commands are used for controlling the high-pressure valves installed in the Automation Manager.

 

Command/Property

Description

ValveName.State

Indicates (and can set) the valve position (A or B).

ValveName.A

Switches the valve to the A position.

ValveName.B

Switches the valve to the B position.

Notes on Default High-Pressure Valve Names

The following names are assigned to the Automation Manager high-pressure valves by default:

AM_HP_1: The first (or only) Automation Manager high-pressure switching valve in the timebase

AM_HP_2: The second Automation Manager high-pressure switching valve in the timebase

 

Low-Pressure Valve Control Commands

The following commands are used for controlling the various low-pressure valves installed in the DC.

 

Command/Property

Description

ValveName.State

Indicates and can set the valve position (Open or Closed).

ValveName.Open

Switches the valve to the open position.

ValveName.Closed

Switches the valve to the closed position.

Notes on Default Low-Pressure Valve Names

The following names are assigned to the low-pressure valves by default:

AM_LP1: The first (or only) Automation Manager low-pressure valve in the timebase

AM_LP2: The second Automation Manager low-pressure valve in the timebase

DC_LP1: The first (or only) DC low-pressure valve in the timebase

DC_LP2: The second DC low-pressure valve in the timebase

DC_LP3...DC_LP6: The third through sixth DC low-pressure valve in the timebase

 

Relay and TTL Control Commands

The following commands are used for controlling the relay and TTL outputs installed in the DC.

 

Command/Property

Description

RelayTTLName.State

Indicates (and can set) the relay position (Open or Closed).

RelayTTLName.Open

Switches the relay to the open position.

RelayTTLName.Closed

Switches the relay to the closed position.

Notes on Default Relay and TTL Output Names

The following names are assigned to the DC relay and TTL outputs by default:

DC_Relay_1: DC relay output 1

DC_Relay_2: DC relay output 2
