Manual – MOVI-PLC® advanced DH.41B Controller

Configuration for a PROFIBUS DP master

Configuration and Startup

The following figure shows the configuration data structure defined in IEC 61158. This

configuration data is transferred to the MOVI-PLC

advanced DHF41B control card

when the DP master is started.

Data integrity Integral data is data that always has to be transmitted between the higher-level control-

ler and the MOVI-PLC

advanced DHF41B control card as one block and must never

be transmitted separately.

Data integrity is particularly important for transmitting position values or complete posi-

tioning tasks. The reason that data integrity is so important is that data which is not

transmitted integrally could come from different program cycles of the higher-level

controller, which would lead to undefined values being transmitted to MOVI-PLC

advanced DHF41B controller.

For PROFIBUS DP, data communication between the higher-level control and the

MOVI-PLC

advanced DHF41B control card is carried out with the setting "Data

integrity over entire length".

7 / MSB 6 5 4 3 2 1 0 / LSB

Data length

0000 = 1 byte/wort

1111 = 16 bytes/words

Input/output

00 = Special identifier formats

01 = Input

10 = Output

11 = Input/output

Format

0 = Byte structure

1 = Word structure

Integrity over

0 = Byte or word

1 = Entire length

Note:

The MOVI-PLC

advanced DHF41B control card does not support the "Special identifier

formats" coding! Only use the setting "Integrity over entire length" for data transmission.
