3.4.5 Mode of Operation of the Counters
Both counters of the CIO 2/4 01 must be configured using system parameters, see Chapter
4.3.1 and Chapter 4.4.1.
The following modes of operation can be implemented:
ƒ Counter function 1 (depending on the count direction input signal)
ƒ Counter function 2 (irrespective of the count direction input signal)
ƒ Decoder operation with attached absolute rotary transducer
3.4.5.1 Counter Function 1 (Depending on the Count Direction Input Signal)
Counter[0x].Auto. Advance Sense
system parameter set to TRUE,
counting with falling edge on input A1 (A2).
Low level on count direction input B1 (B2) increments (increases) the counter value,
High level on count direction input B1 (B2) decrements (decreases) the counter value.
For this mode of operation, the Z1 (Z2) input must be set to low level. The counter can be
reset with a short-time high level.
Input C1 (C2) has no function.
The counter can be reset within the programming tool using the
