Name: EnableMask
Declaration: INPUT
Data type:
BYTE
Range of
values:
B#16#00 ... B#16#FF
Explanation Enable mask for the counting inputs
With this parameter "EnableInMask" it is possible to specify in the form of a bit
mask at which inputs in the input byte count pulses are actually connected.
The following applies to every bit in the bit mask:
• 0 = Input bit blocked for acquisition
•
1 = Input bit enabled for acquisition
The input of the mask is only permitted in hexadecimal format B#16#00 to
B#16#FF.
Input as an 8-bit binary number from 2#0 to 2#1111 1111 is not possible with
the data type BYTE.
The assignment of the bits in the mask to the inputs in the input byte "InByte":
InByte
.7 .6 .5 .4 .3 .2 .1 .0
EnableMask B#16# 0 … F 0 … F
Example: EnableMask B#16#83
Enabled are: Inputs .7, .1 and .0
Blocked are: Inputs .6 to .2
Name: CntIn_0 ... CntIn_7
Declaration: INPUT
Data type:
COUNTER
Range of
values:
C0 or C1 ... Cn
(n depends on the CPU)
Explanation Pulse counter
For each of the enabled counting inputs a SIMATIC counter needs to be spec-
ified for the corresponding parameter CntIn_0 ... . "CntIn_7". With each pulse
acquired, the SIMATIC counter is incremented.
The counters set here must be specified as input counters (parameter Coun-
ter_1 ... _4) in the actual counted value function blocks "Cnt01D_S" and
"Cnt04D_S". These function blocks out read the assigned counter and then
reset it.
As the placeholder for parameters that are not required, it is recommended to
specify the counter C0.
