MpmSimPlutoDevice

public MpmSimPlutoDevice()

Method Detail

initDevice

protected void initDevice()

Performs basic initialization.

Overrides:

initDevice in class org.lsst.ccs.subsystem.common.devices.pluto.PlutoDevice

initialize

protected void initialize()

Performs full initialization.

Overrides:

initialize in class org.lsst.ccs.subsystem.common.devices.pluto.PlutoDevice

close

protected void close()

Closes device connection.

Overrides:

close in class org.lsst.ccs.subsystem.common.devices.pluto.PlutoDevice

checkChannel

protected int[] checkChannel(String name,
                             int hwChan,
                             String type,
                             String subtype)

Checks a channel's parameters for validity.

Overrides:

checkChannel in class org.lsst.ccs.subsystem.common.devices.pluto.PlutoDevice

Parameters:

name - The channel name

hwChan - The hardware channel number

type - The channel type string

subtype - The channel subtype string

Returns:

A two-element array containing the encoded type [0] and subtype [1] values.

readChannelGroup

protected void readChannelGroup()

Reads all referenced channels.

Overrides:

readChannelGroup in class org.lsst.ccs.subsystem.common.devices.pluto.PlutoDevice

readChannel

protected double readChannel(int hwChan,
                             int type)

Reads a channel.

Overrides:

readChannel in class org.lsst.ccs.subsystem.common.devices.pluto.PlutoDevice

Parameters:

hwChan - The hardware channel number.

type - The encoded channel type returned by checkChannel.

Returns:

The read value

isPLCActive

public Boolean isPLCActive()

Tests whether the PLC is active

Overrides:

isPLCActive in class org.lsst.ccs.subsystem.common.devices.pluto.PlutoDevice

Returns:

Whether the PLC is active, or null if offline

setSwitch

public void setSwitch(int sw,
                      boolean on)

Sets a switch on or off. For the vacuum Pluto, this is implemented as a pair of push buttons, one for on, one for off.

Overrides:

setSwitch in class MpmPlutoDevice

Parameters:

sw - The switch number.

on - The on state to set: true or false

isSwitchOn

public Boolean isSwitchOn(int sw)

Gets the on state of a switch. The state is not the state of the bit that was toggled, but is read back either directly from the controlled hardware, or from the PLC output line.

Overrides:

isSwitchOn in class MpmPlutoDevice

Parameters:

sw - The switch number.

Returns:

Whether the switch is on
