9 Object directory
9.1 Object types, data types
A parameter in the object directory can be a simple value, an array or a data structure.
encoTRive uses the following types, which are distinguished by the
object code :
Object code Name Meaning
7 VAR Simple value, e.g. INTEGER8
8 ARRAY Array from several elements of the same data type
9 RECORD Data field, which is a combination of various simple data types
Table 23: Object codes in encoTRive
In the case of an ARRAY or RECORD parameter, the individual elements are
accessed via the subindex. For simple values (VAR), the subindex is 0.
A parameter or an element of a parameter also has attributes which define the access
to this parameter:
Attribute Meaning
rw read/write: Parameter can be read and written
ro read only: Parameter can only be read
wo write only: Parameter can only be written
const Value is constant and read only.
