6. Function blocks
6.1 Manufacturer function blocks
6.1.4.5 VC - Value limitation
General
easyE4 base devices provide 32 value limitation function
blocks, VC01 through VC32.
These function blocks can be used to output values within spe-
cific limits.
Operating principle
The lower and upper limits are set using function block inputs SL (Low) and SH (High).
The value at function block output QV will follow the value at function block input I1 as
long as the latter falls within the limits. Values outside of the range will be truncated
accordingly.
EN=0 will carry out a reset and function block output QV will be set to a value of 0.
