Function Of The Digital Inputs And Outputs; Digital Output - Siemens SENTRON PAC4200 Manual

Any limit values and the digital inputs of SENTRON PAC4200 can be selected at the inputs
of the upstream logic function blocks. The input value is the truth value of the monitored
signal:
● True: Limit value is violated or input is active.
● False: Limit value is not violated or input is not active.
Displaying limit violations
SENTRON PAC4200 outputs limit violations at the digital output or via the interfaces.
Limit violations are countable. One of the limit values can be assigned to the universal
counters.
Limit violations are recorded as events with additional information on the monitored
measured variable and the monitored threshold.

Digital output

The following functions can be assigned to the digital output:
● Not used
The digital output is deactivated.
● Device is ready for operation
The digital output is activated.
● Remote control
The digital input is remotely controlled.
● Rotation
The digital output is switched on by a counter-clockwise rotating electrical field and
remains active while the direction of rotation of the field remains unchanged.
● Energy pulse
The digital output outputs the parameterized number of pulses or edges per energy unit
(e.g. kWh). The specified energy counter is evaluated here.
