App. Notes: GPL HVAC Library
section.
•
For information on the definition and the initial configuration of the
objects and the function blocks, use GPL to examine this compound.
•
You must define all the following AI, PIDL, and AOD objects as part
of the same DCM:
- the AI object connected to the SA-T block
- the DC-CTRL (PIDL object)
- the CLG-PTP (PIDL object)
- the AOD object linked to the CLG-AOD connection block
- the AOD object linked directly to the DMP-OUT connection block,
if DMPLOGIC is not used
•
If you’re using the DMPLOGIC compound as an accessory, you must
also define all the AI, PIDL, and AOD objects used with that
compound as part of the same DCM discussed above, including the
following:
- the AI object connect to the MA-T connection block
- the AOD object connected to the DMP-AOD connection block
- the MINLIMIT (PIDL object)
- the MAXLIMIT (PIDL object)
- the MAPLL (PIDL object)
•
If a PIDL’s object name is changed, make sure all references to that
object name are also changed.
•
If the CLG-ENA or STATUS connection blocks are not used, connect
them to a binary constant with a value of 1.
