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
,
(
¶ 7.6-5)
)
l
Process output data (PO data, index = 6001
hex
,
(
¶ 7.6-6)
)
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 settings are made by means of
– DIP switch
(
¶ 7.5-2)
or
– Code L-C1910
(
¶ 7.5-4)
.
The contents of code L-C1910 is overwritten when the DIP switch is used
because the DIP switch settings have higher priority.

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 or using the switch S7 at
the front.
Different controller signals can be assigned to the PI and PO data
words (see
(
¶ 7.6-7)
).
