The input configuration option defines if the inputs are high or low side switching, i.e. switch to +V or
0V (return). The default option is for high-side switch (to +V). Setting this option to TRUE will select
the switch operation to 0V (return).
Ratiometric = < TRUE | FALSE (default) >
This option allows the input thresholds to be defined either in terms of their absolute voltage or
normalised to the nominal field supply voltage. The default operation is for the thresholds to be defined
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 will be re-scaled according to the current field supply voltage, e.g. a
threshold value of 12V with an actual field supply of 30V will result in an actual threshold of 15V. If the
field supply voltage is out of range, a line fault condition will be generated.
Output Modules
There is one possible entry for this template; LOGICAL. The syntax and function is described below.
These settings apply to the entire module.
LOGICAL = < TRUE | FALSE (default) >
This configuration option defines how the module timestamps changes of state for the output channel.
When set to True, the module will timestamp an output change when it receives a change of state to
the logical output control signal. When set to False (default) the module will timestamp 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. It is usually unnecessary to change this setting in
most applications.
2.3.13. Module Flags Template Editor
From the Template Creation window, select Module Flags, then select the Edit button. This will
cause the Command Line Interface (CLI) Entry window shown in Figure 15 below to be displayed.
Figure 15 Module Flags Template Editor
The Current CLI Entries area of the CLI Entry window will normally be blank when initially editing this
template. If there are entries in this area, they may be deleted by highlighting them and selecting the
Remove Entry button. Each entry must be deleted individually.
New instructions are entered in the Please Enter CLI Instruction area in the format shown above,
then added to the template by selecting the Add Entry button.
