Controlling a DX-120 Ion Chromatograph

IC Control
Controlling a DX-120 Ion Chromatograph

The following commands are available for controlling DX-120 operating functions:

Controlled AC	Turn the AC power outlet on the DX-120 rear panel on and off. This provides on off control of an external accessory connected to the outlet. See the DX-120 operator’s manual for cabling instructions.
Column/Eluent	If the DX-120 is in Column Mode, the Column command sets the flow path to column A or column B. If the DX-120 is in Eluent Mode, the Eluent command selects the eluent reservoir (A or B). Refer to Selecting the DX-120 Mode. Note: These commands are active only if the DX-120 is equipped with the dual-column option.
Data Collection Rate	Sets the Data Collection Rate of the detector.
Eluent Pressure	Turns the pressure to the eluent reservoir(s) on and off.
Pressure Unit	Selects the units of pressure to use (psi or MPa).
Pump	Turns the pump on and off.
SRS	Turns the current supplied to the Self-Regenerating Suppressor (SRS) on and off.

These commands can be included in a Program, executed directly from the Commands dialog box (to do so, select Command… on the Control menu), or linked to a control on the control panel.

To link a command to a control, place an edit box or switch control on the control panel (see Layout Toolbar). Then, link the control to an object property. For example, to turn the DX-120 pump on and off from the control panel, link the Pump object property to a switch control. For more information, refer to How to: Controlling Devices from the Control Panel Linking a Control to a Device.

The corresponding commands in the program are as follows:

;	Only for a DX-120 equipped with the dual-column option.

0.000	Data_Collection_Rate	=Value [Hz]
0.000	Eluent	=A/B

;	Only for a DX-120 equipped with the dual-column option.

0.000	EluentPressure	=On/Off
0.000	PressureUnit	=psi/MPa
0.000	Pump	=On/Off
0.000	SRS	=On/Off
