External Input 2
The number of available digital inputs can be expanded by using the CDB620/CDM420
connection module in conjunction with the CMC600 parameter memory module. The
purpose of the CMC parameter memory module is to act as an input expansion module
and convert a digital signal into a command. External digital inputs generally respond
more slowly than the internal digital inputs of the sensor.
group contains the parameters for adjusting external digital input
2.
Control system
parameter allows you to choose between a configuration based on
length units and a configuration based on time units.
•
DISTANCE-CONTROLLED
: The configuration is based on distance increments in mm.
These are either generated by the configuration software (SOPAS)/CAN interface
or via a rotary encoder at the digital input.
•
TIME-CONTROLLED
: The configuration is based on times entered in ms.
Sensitivity
parameter allows you to choose between edge control and level control.
•
EDGE
: The digital input responds to the switch between Low (0) and High (1)
according to how the
parameter is configured. Any signal that is permanently
present is ignored.
•
LEVEL
: The digital input responds to a permanently present signal according to how
the
parameter is configured.
Logic
parameter is used to select the polarity for the
parameter.
•
NOT INVERTED
: The digital input responds to a rising edge, i.e., to a switch from Low
(0) to High (1), or to a High signal (1) that is permanently present.
•
INVERTED
: The digital input responds to a falling signal edge, i.e., to a switch from
High (1) to Low (0), or to a Low signal (0) that is permanently present.
Debouncing
Depending on how the
parameter is configured, the
param‐
eter specifies the minimum distance in mm or the minimum time in ms for the signal at
the external input. If the value is not achieved, the signal is not detected.
Depending on the application, this value may have to be adapted in line with the read
cycle rates required.

FC1-Value on First Position
parameter can be used to define an alternative charac‐
ter for the FC1 character (control character at the start of the code) in the case of the
EAN 128 code format.
Up to three characters can be defined. The values must be entered as decimal num‐
bers.
