P275 Scaled Discrete Input Value

Shows the current value of the discrete input after any scaling is applied.

Primary Index	Discrete input
	Display: view only
	Values: dependent on the function of the discrete input

	Range of Values	Function (P270)
Values	1	Forced ON
	0	Forced OFF
	0 (DI open), 1 (DI closed)	Normally Open
	0 (DI closed), 1 (DI open)	Normally Closed

Readings are updated continuously even in PROGRAM mode. The value signals a level override event.

Standard Data Logging (P300 to P321)

All records can be reset by pressing the CLEAR keys.

Record Temperatures (P300 to P303)

These features display the high and/or low temperatures in °C. When a parameter relating to a TS-3 Temperature Sensor is accessed, the Point Type display changes to the

TS-3 symbol .

If the unit is powered up without a temperature sensor connected, the value –50°C is displayed. This information can help trace problems with both built in and external temperature sensors.
