Note 1: Swap byte order
Some DP-masters handle lower bytes and higher bytes of a word in a reverse order than
the 32DP-IF. To enable the module to communicate with these masters, bit 0 of data register
D8021 can be set. If bit 0 is “1”, the low order byte and the high order byte of each user data
word and of the user specific diagnosis will be swapped. Bit 0 of D8021 can also be set or
reset by the second user defined parameter byte received from a master. The default value
after power up is “0”.
Note 2: Baud rate
This device shows the current baud rate of the Profibus-DP network. The baud rate
depends on the DP-master settings. The following table shows the supported baud rates
and the value of D8024. If the module is in baud search mode, this value frequently
changes until the module has found a supported baud rate as follows.
