Dear 东倒西歪,
You can calculate integral and derivative by setting appropriate
parameters for the FB_PIDR function block in the src/fb/rt/process
folder. See
http://www.holobloc.com/doc/fb/rt/process/FB_PIDR.htm for
documentation.
By the way, you can also see this documentation by going to the
experimental navigation page
http://www.holobloc.com/doc/navigator.htm
and selecting the block from the appropriate folder (not all FB types
are documented this way yet, but this one is). Some of the
documentation pages even have the FB or system configuration tester
built in; see E_CTU for example.
