Flags Templates

Defines if the inputs are high or low side switching. For example, switch to +V or 0V (return). The default option is for high‑side switch (to +V). Setting this option to TRUE selects the switch operation to 0V (return).

Enables the input thresholds to be defined either in terms of their absolute voltage or normalized to the nominal field supply voltage. The default operation is to define the thresholds in absolute voltage.

When the ratiometric threshold operation is enabled, the field supply must be connected to the monitoring terminals on the field termination unit. In ratiometric mode the range of voltages for the thresholds is 0 to 24V, the value is re-scaled according to the current field supply voltage. For example, a threshold value of 12V with an actual field supply of 30V results in an actual threshold of 15V. If the field supply voltage is out of range, a line fault condition is generated.

Defines how the module timestamps changes of state for the output channel. When set to True, the module timestamps an output change when it receives a change of state to the logical output control signal. When set to False (default) the module timestamps an output change of state when the measured voltage and current reflect an actual change of state in the output control circuit. Propagation delay between receiving the logic control signal and driving the output control signal is typically less than 1 millisecond. For most applications, it is usually unnecessary to change this setting.
