The vhqControl(1) application uses configuration files both to form a connection to vhq 2xx modules it is controlling and to load previously saved settings. These configuration files are Tcl scripts that set agreed upon variables to the needed configuration values. Configuration scripts have two sorts of variables Identification and Settings variables. Identification variables identify the module both to humans and to computers, providing the necessary information to connect to and control the module. Settings variables provide saved settings information that can be restored into a module once a connection to it has been established.
Provides a human readable name for the module.
Provides the number of the VME crate in which the module is stuffed. If not provided, this defaults to zero.
Provides the base address (A16) at which the module has been configured. See the VHQ manuals for more information on setting the module base address. It is important not to configure two modules at the same base address in the same VME crate. This variable is mandatory.
Defines the maximum voltage the module can output in volts. This variable is mandatory.
Defines the maxiumum current the module can output in micro-Amps. This variable is mandatory.
Sets the current limit for channel. The channel index can be either a or b. Recall that array indices in Tcl are strings. The units of measure are micro-Amps
Sets the ramp speed for channel. The channel index can be either a or b. The units of measure are Volts/Sec.
Sets the target voltage for the channel. The channel index can be either a or b. Note that setting this variable does not cause the module to perform a ramp. The units of measure are Volts.
