8-2 AsconControlLib
The AsconControlLib is a function block library dedicated to the process control. It
uses the basic functionalities dedicated to the P.I.D. implementation present in the
firmware of the control unit (MP-01) device in order to provide a ready to use
solution.
In the library there is the implementation of a complete standard regulator
in both versions: single action and double action for heat and cool applications.
Please note that are also different function blocks dedicated to the tuning
algorithms in both version “Step Response” and “Natural Frequency”.
The following table gives the complete list of the function blocks in the library (see
the “
IEC 61131-3 Function Block Library ” [4] manual for details).
LIMITER_VALUE Limiter Function Block
MIN_MAX_SELECTOR Min/Max Selector Function Block
MONOSTABLE_DS Monostable with Delay
MONOSTABLE_NED Monostable with Delay on the Negative Edge
