Commissioning of PROFIBUS

Detailed commissioning steps

3. Go to the Bus parameters tab to set the baud rate for PROFIBUS:

parameter:

The "Byteorder wordmodules motorola" parameter determines how the data are

copied from PROFIBUS to the process image.

Setting

Description

No

Standard setting:

The data are received by the bus in Motorola format (Big Endian) and copied into the Intel format

(Little Endian). The user sees a correct integer value (INT) (example: ’0x1234’  ’0x1234’).

We recommend to keep this setting. Like this, the slave data are correctly transferred to the

process image.

Yes

The data are copied without being transposed from the bus to the process image. The user sees

a transposed integer value (INT) (example: ’0x1234’  ’0x3412’).

• Compatibility with other projects from the version 1.5
