User Manual

9.622 Selector-Two-Way

The Selector-Two-Way logical device provides a simple way to show multiple parameter values in a single entry field of the user interface.

The device selects one of up to 12 arbitrary parameters on the M&C and lets this parameter be monitored and controlled with its value parameter. The IDs of the parameters to select are defined in the device's setup with the pos.##.id configuration parameters.
To select a parameter, the device listens to one parameter in the M&C and compares the actual reading of this parameter to the reference values defined in the device's setup with the pos.##.select configuration parameters. If the actual reading of the selection parameter matches the reference value of a position, this position gets selected.
If the reading of the selection parameter matches none of the defined reference values or if the selection parameter provides no reading at all, a default position gets selected. The default position is defined in the device's setup as well.
The parameter addressed by the selected position of the selector appears in the value parameter of the device. value always shows the actual value of this parameter. value also has the data type and range of the addressed parameter. This means you also may command the addressed parameter by changing value in the user interface. This makes the Selector-Two-Way work bidirectional, which gives the device its name.
When selecting a parameter for value, the device also sets a parameter called label with a test defined for this selector position. You may use this label to identify in the user interface which parameter is actually seen in value.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

--- This page shows the selection state and actual value
--- The device info page.
--- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to interconnect the Level-Set device to the devices it monitors and controls.

parameter	description
selectId	The message ID for the parameter to monitor. e.g S1.position for a waveguide switch.
defaultPos	If you want to append a unit (or any other kind of text) to the output value, you can enter it here.
pos.01.id .. pos.12.id	The message ID of the parameter to monitor and control with the value parameter of this device if this particular position is selected.
pos.01.select .. pos.12.select	If the value of the parameter monitored with selectId equals the value entered here, the selector switches to this position. 'select' values must be unique, if two positions have the the same 'select' value configured, the device's behavior is not defined.
pos.01.label .. pos.12.label	The value to be set at the label parameter of this device if this particular position is selected.

Application example

You have to HPA's in an 1+1 redundant configuration. Both HPAs provides an output power, but you want only display the output power of the active HPA in the main screen to the operator. The waveguide switch's name is S1 with the position A and B and the HPA names are HPA-1 and HPA-2 :

parameter	setting
selsectId	S1.position
pos.01.id	HPA-1.meas.fwdPwr
pos.01.select	A
pos.01.label	HPA 1 power
pos.02.id	HPA-2.meas.fwdPwr
pos.02.select	B
pos.02.label	HPA 2 power
