checkChannel in class PduCommonDevice

Parameters:

name - The channel name

hwChan - The hardware channel

type - The channel type string

subtype - The channel subtype string

Returns:

Two-element array containing the encoded type [0] and subtype [1]

Throws:

Exception - If parameters are invalid

readChannel

protected double readChannel(int hwChan,
                             int type)

Reads a monitoring channel.

Overrides:

readChannel in class PduCommonDevice

Parameters:

hwChan - The hardware channel number

type - The encoded channel type

Returns:

The read value
