7.6.1.3 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)).
