7.2.1 Data module HGPPI_COMMAND−LIST"
The data module HGPPI_COMMAND−LIST" includes a list
of commands that can be executed by the HGPPI. Each
command is made up of a function number and the desired
setpoint value parameters.
The HGPPI−... often executes the same command several
times within one application. In the command list, each com
mand is programmed only once. The sequence control trans
fers the number of the command (array index) to be executed
to the FB10. This loads the command from the data module
DB5 HGPPI_COMMAND−LIST". The command data is trans
ferred to the HGPPI−... with the start command.
You can create a program with a certain command sequence for
a specific application. If components of other dimensions are to
be gripped depending on the process, only the FB5 has to be
adapted. The actual sequence control remains unchanged.
This offers you enormous flexibility and can save a lot of
memory in the PLC in complex applications.
