Configuration
T8448 and T8449 inputs may be monitored by the application through either the STATE or the AI
boards on the equipment definition. There is no Boolean point available for digital inputs.
The AI board provides the measured voltage in 500 ths of a volt (0V = 0, 24V = 12,000 etc.) This can be
changed to engineering units with a conversion table, as for analogue inputs.
The STATE board reports a numerical state according to threshold settings, exactly as for digital input
modules (except the voltage scaling is slightly different). Refer to the section on Digital Input
Thresholds above. The STATE input is an integer and reports 2 for off/open and 4 for on/closed.
Note that the LINE_FLT board will provide the same fault status as for digital inputs above.
