4.2
PLC data types
The data for calculating the HCS configuration as well as the data of the SIPLUS
HCS to be written and to be read are stored in data blocks "LHcs4x00_Config",
"LHcs4x00_Put" and "LHcs4x00_Get". The FBs and the FC access these DBs
(defined via PLC data types).
Below, the elementary PLC data types "LHcs4x00_typeConfig" (chapter 4.2.1),
"LHcs4x00_typePut" (chapter 4.2.7) and "LHcs4x00_typeGet" (chapter 4.2.35) as
well as the PLC data types integrated therein are explained.
Note
This chapter is intended for a better understanding of the individual tags.
The configuration is described in chapter
4.2.1
"LHcs4x00_typeConfig"
The PLC data type "LHcs4x00_typeConfig" includes the configuration
specifications for the HCS4x00 heating control systems.
