NOTE
The external digital inputs are software-controlled and therefore do not offer the same
timing precision as physical digital inputs. The external digital inputs may not be suit‐
able for time-critical applications.
For the electrical characteristic data of the two external digital inputs, see the respec‐
tive connection diagrams for the connection modules in these operating instructions.

Wiring the digital outputs
The physical digital outputs “Result 1” to “Result 4” or “Result 1” and “Result 2” are
used to signal events in the read operation. Different functions can be assigned to
them independently of each other for this purpose. If the assigned event occurs, then
the corresponding digital output becomes live after the end of the read cycle for the
selected pulse duration, for example (default).
The full complement of digital outputs is available at each of the following locations:
•
Male connector of the device (M12, 17-pin, A-coded)
•
Open end of the adapter cable (female connector, M12, 17-pin, A-coded/open
end)
•
CDB650-204 connection module
The four digital outputs are available in the CDM420-0006 connection module but
reduced to two outputs (“Result1“, “Result2“). Connect the device to the
CDM420-0006 connection module using an adapter cable (female connector, M12, 17-
pin, A-coded / male connector, D-Sub-HD, 15-pin).
