Siemens SIMATIC ET 200iSP User Manual

• 1 x 32-bit down counter (cascading counter function)
• Setting a setpoint via the PIQ
• GATE function
• You can con󹪝gure the control signals of the counters:
– Con󹪝guration "2 Count/ 6 DI NAMUR": Two counters are con󹪝gured. The control signals of
the counters are stored in the POI (process output image).
– Con󹪝guration "2 Count/ 6 Control": Two counters are con󹪝gured. The control signals of
the counters are stored in the POI (process output image). In addition, they are controlled
by the digital inputs of the 8 DI NAMUR.
• You con󹪝gure and parameterize the counters of the electronic module 8 DI NAMUR in the
con󹪝guration software, e.g. HW Con󹪝g.
4.17.2 Principle of operation
16-bit up-counters (standard counting function)
The counting range is always 0 to 65535.
The counter value increases by the value 1 with each counting pulse at the digital input. When
the count limit is reached, the counter reading is set to the value 0 and incremented starting
from this value.
If there is counter over󹪞ow, the corresponding output is set in the PII.
A positive edge of the Reset output control signal resets the output in the PII. The current counter
value is not a󹪜ected by this.
In 16-bit up counting operations, the system does not set any outputs in the POI. These are
always reset.
The positive edge of the Reset counter control signal resets the counter reading to the value 0
and the set counter output.
The GATE control signal pauses the counting on a positive edge. Count pulses are processed at
the digital input again, but only at the negative edge. The "Reset counter" control signal also has
an e󹪜ect when TOR is activated.
