Output
The output VC..QV provides the input value within the defined limits as an
integer. You can assign the following operands to output
…
QV:
•
Analog output QA01
•
Markers MD, MW, MB
Function of the function block
The value is accepted at input VC…I1 if the enable coil is active. If the value
is greater than the upper limit value or less than the lower limit value, the
appropriate limit value is output at VC…QV.
5.35 Example with timing relay and counter function block
A warning light flashes when the counter reaches 10. In this example the
function blocks C01 and T01 are wired in the standard circuit diagram and
their inputs/outputs are defined.

￫
The function block must be enabled so that it can work. Coil
VC…EN is active. If coil VC…EN is not active, the entire function
block is deactivated and reset. The output value is set to zero.
