Configures the expiration states for an analog watchdog timer task.
The DAQmx Watchdog properties contain additional watchdog timer configuration options.
task in is the name of the task to clear. Unlike the task/channels in input on some nodes, you cannot wire a virtual channel to this input.
expiration states contains the states to which to set analog physical channels when the watchdog timer expires. Each element of the array contains an analog physical channel name, the corresponding expiration state, and the output type for that analog physical channel. The units of expiration state must be specified in volts for an analog output voltage expiration state, or amps for an analog output current expiration state.
physical channel is the analog output channel to modify. You cannot modify dedicated analog input lines. The DAQmx physical channel constant lists all lines and ports for devices installed in the system.
You also can wire a string that contains a list or range of digital lines or ports to this input. If you have an array of lines or ports, use the DAQmx Flatten Channel String node to convert the array to a list.
expiration state specifies the value to set the channel to upon expiration.
output type specifies the output type of the physical channel.
Expiration does not affect the port. Do not change the state of any lines in the port, and do not lock the port.
task out is a reference to the task after this node or function completes execution.
