3 Counter module
Assembly
The counter module provides two channels, each with one input
for pulse frequencies up to 100 kHz, a reference input and two
digital outputs.
You can connect single-phase or 2-phase incremental encoders
(with/without quadruple evaluation for the 2-phase). The type of
counter (linear or ring counter) is set with the aid of DIP switches.
RESET button on the module
You operate the RESET button (by using a pointed object) to reset
the parameters to their initial (default) setting. When the button is
pushed, the ERROR-LED in the LED display lights up red.

The LED lights up when a voltage is present at the input,
regardless of whether the signals are inverted or not.
PW Indicates the supply voltage for the module:
on: OK
blinking: • After incorrect parameter entry
• With the counter type “Ring counter”, the
LED blinks if voltage has been applied to the
PLC. After you have set the preset value
(WRITEPRESETVALUE) and the comparison
value (WRITESETTINGVALUE2), the LED lights
up continuously.
