5.7.2.5 FC PulseCounter
Function
The FC PulseCounter is responsible for count pulse acquisition.
A maximum of 8 pulse strings are detected via digital inputs and fed to the function blocks
with the aid of SIMATIC counters that put together the counted value frames (Cnt01D_S,
Cnt04D_S).
The acquisition of the count pulses is time-controlled To do this the FC PulseCounter must
be included in a cyclic interrupt OB, e.g. OB35. The call interval of the cyclic interrupt OB
must be matched to the pulse duration of the count pulses. You will find more information on
count pulse acquisition with the cyclic interrupt OB in the section Cyclic interrupt OB
(Page 138).
Parameter
Name: InByte
Declaration: INPUT
Data type:
BYTE
Range of
values:
Input bytes PEB0 ... PEBn
Memory bytes MB0 ... MBn
LB0 ... LBn
Data bytes DBm.DBB0 ... n
If an input byte of a digital input is specified, this must be the address of the
I/O byte (PIB) directly from the digital input modules. The current status of the
count input can only be detected reliably by direct access.
When reading out from the process image of the inputs (PII) count pulses
could remain undetected.
Explanation: Input byte for count pulses.
The parameters for inputs for count pulse acquisition can can be set in bytes.
