* The values will only be accepted after the state has changed from "Pre-Operational" to "Operational".
09 Counter function* Bit 5 ... 0:
0b000000 = continuous counting
0b000001 = single counting, main counting direction is forward
0b000010 = single counting, main counting direction is
backward
0b000100 = single counting, no main counting direction
0b001000 = periodic counting, main counting direction is
forward
0b010000 = periodic counting, main counting direction is
backward
0b100000 = periodic counting, no main counting direction
Bit 7 ... 6: Reserved
0x40
0A Comparator* Bit 2 ... 0: output switches (... if condition is met)
0b000 = never
0b001 = count value  comparison value
0b010 = count value  comparison value
0b100 = count value = comparison value
Bit 3: Invert counting direction track B
0 = no (do not invert)
1 = yes (invert)
Bit 6 ... 4: Reset
0b000 = deactivated
0b001 = HIGH level
0b011 = rising edge
0b101 = one-time rising edge
Bit 7: Reserved
0x00
0B Signal evaluation* Bit 2 ... 0: Signal evaluation
• 0b000 = counter deactivated (the other parameter data
details for the counter are ignored)
• 0b001 = rotary transducer 1-fold (connection to "A/pulse"
input)
• 0b010 = rotary transducer 2-fold (connection to "A/pulse"
input)
• 0b011 = rotary transducer 4-fold (connection to "A/pulse"
input and "B/direction")
• 0b100 = direction (pulse at "A/pulse" input and direction at
"B/direction" input)
Bit 6 ... 3: Hardware gate (HW gate)
• 0b000 = deactivated (counter starts by setting SW gate)
• 0b001 = activated (HIGH level at gate activates the HW gate.
Counter starts if HW and SW gate are set.)
Bit 7: Gate function (internal gate)
• 0= abort (counting process starts again from loading value)
• 1 = interrupt (counting process is continued with counter
content)
0C Final value Upper limitation of the counting range 0x00
0D Start value Lower limitation of the counting range 0x00
0E Hysteresis The hysteresis for instance serves to avoid frequent switching
operations of the output and/or triggering of the alarm when
the count value is within the range of the comparison value. For
the hysteresis you can select a range between 0 and 255. With
the settings 0 and 1 the hysteresis is switched off.
The hysteresis has an effect on the zero crossing, comparison,
overflow/underflow.

0F Pulse The pulse duration indicates for how long the output is to be set
if the parameterised comparison criterion is reached or
exceeded. The pulse duration can be specified in steps of
2.048 ms between 0 and 522.24 ms. If the pulse duration is = 0,
the output is set until the comparison condition is no longer met.
