ment B
a Enter counter status In the user program, assign the default
counter status to OutputData.NewCounter­
Value
b Transfer counter status In the user program, set Out­
putData.SetCounter
c Acknowledge transfer The module sets InputData.SetCounter­
Done; InputData.Underflow and In­
putData.Overflow are reset
D Finish transfer In the user program, reset Out­
putData.SetCounter
e Ready for new function The module resets InputData.SetCounter­
Done
4.1.5.5 Multiple evaluation
The module can evaluate the counter pulses once, twice or four times. Multiple evaluation
increases the number of measuring steps and reduces the output frequency of the incre­
mental encoder.
Multiple evaluation is only possible in incremental encoder operating mode.
} Single evaluation option:
Each rising edge at channel A increases the counter status.
} Double evaluation option:
Each rising and each falling edge at channel A increases the counter status.
} Quadruple evaluation option:
Each rising and each falling edge at channel A and channel B increases the counter
status.
The Double evaluation and Quadruple evaluation options may not be used for failsafe
applications.
