IGITAL INPUTS AND OUTPUTS
CONDITION: The Digital I/O option board, analogue output option or one of the fieldbus options should be
installed in the weighing indicator, to use digital control inputs and setpoint output signals.
APPLICATION: Digital inputs are used to control the instrument and the digital outputs can be used at basic
weighing, checkweighing, classifying, peak holding and filling applications to control gates, valves etc. or to
produce alarm. Digital inputs and outputs are set to the classifying, checkweighing, peak holding or filling
operations automatically.
RELATED PARAMETERS: Sub-blocks 35- and 36-.
You may enter limit values of the item after pressing
key or you may call them from Memory. Set
Memory has 500 pcs item record capacity. Each item has 5 or 6 set entries which depends on the application.
This section describes functions of digital ports at basic weighing. These functions are automatically changed
to In/Out functions of selected SmartAPP application.
The digital inputs and outputs can be programmed to use them as a Remote IO of PLC over fieldbus
additionally
to their usage at weighing related functions. Remote IO’s of PLC can be used for level control of
material tank, conveyor control, solenoid control, alarm etc.
