Process data configuration
Some data important for the process must be transmitted as quickly as possible.
These data are called process data and stored in the I/O area of the controller for
access from the INTERBUS master.
The process data are cyclically exchanged between the controller and the
INTERBUS master.
The process data of a Process-data configuration have a certain ” Process data
structure“ .
The process-data structure is subdivided into
l
Process input data (PI data, index = 6000
hex
,
(

)
l
Process output data (PO data, index = 6001
hex
,
(

)
The controller receives control information from the INTERBUS master and sends
status information to the master.
The Lenze setting for the process-data length is 4 byte.
The PD length is set under code L-C1910.

Note!
The assignment of the AIF-CTRL control word to PO data is only
useful, if the Drivecom status machine is switched off. This is
achieved by entering “ 0” under L-C1911.
Different controller signals can be assigned to the PI and PO data
words (see

¶ 5.6-6)
).
