Up and down count with
two counting signals by
90° out of phase
The counting direction is

Single, double or quadruple
evaluation is possible.
Programming line 25 to

8 Output responses (output mode)
The behavior of the signal outputs is defined by the following set-
tings under the programming field 3: Operating mode, reset mode,
take-over of preselections, output logic and output time P1, P2 as
momentary
or latched signal
signal.
The following diagrams illustrate some examples:
