Parameter display and parameter set for high-speed counters:
In the parameter display of a counter relay you change
setpoint values and/or the preset value and the enable of the
parameter display.
Value range
The function block operates in the integer range from
–2147483648 to 2147483647.
Behaviour when value range is exceeded
• The function block sets the switching contact CH..CY to
status 1.
• The function block retains the value of the last valid
operation.
Inputs
The function block inputs
>SH, >SL and >SV can have
the following operands:
•Constants
• Markers MD, MW, MB
• Analog inputs IA01 to IA04
– IA01: Terminal I7
– IA02: Terminal I8
– IA03: Terminal I11
– IA04: Terminal I12,
• Analog output QA01
• Actual value …QV> of another function block

CH01 High-speed counter function block number 01
+ Appears in the parameter display
>SH Upper setpoint
>SL Lower setpoint
>SV Preset actual value
QV> Actual value in RUN mode
h
The counter CH counts on every rising edge at the counter
input. If the value range is exceeded, the switching contact
CH ..CY switches to status 1 for one cycle per rising edge
detected.
