2.5.1.1.3. 16-bit counter
The first 16 input channels have each a 16 bit counter. Thus, events as light
barriers, turnstiles or push-buttons are counted. Easy logical circuits are
realizable, which may e.g. switch one or several outputs, if a counter reached a
certain amount (set-point is reached). Please refer to the manual ”RO-series” to
implement such logical circuits into software.
2.5.1.1.4. Registering short input pulses
Short input pulses between to read-out cycles are registered through an
additional logic and can be separately read-out. A registered pulse on one or
more inputs is signalized by the LED ”Inputs: Change” on the control module.
The LED is extinguishing, if the software-register of the input state change is
read out by the user. For more indformation, see ”Register assignment”.
2.5.1.1.5. Galvanically decouppled through optocouplers
AC input optocouplers provide a galvanic isolation of the module towards the
connected equipment. They also provide a safe connection to the module for
reverse currents and high voltage peaks.
