Mode 2 - PPO 4 Word mode

PPO 4 word mode of non-cyclic data is a simple method of accessing non-cyclic data
without the need for the telegrams required with Mode 1 non-cyclic data and its
associated overheads. Mode 2 has the disadvantage of using four words of mappings
and reduces the available free mappings accordingly.

8.2.1

Mapping for PPO 4 Word non-cyclic data

To configure an SI-Interbus in slot 3 for PPO 4 Word mode non-cyclic data, the following
steps must be performed:

•

Set Pr

17.005

to the required mode

•

Set Pr

17.032

to On to reset and reconfigure the SI-Interbus

When the SI-Interbus re-initialises, it will map cyclic data IN words 0 to 3 and OUT
words 0 to 3 to the PPO 4 Word protocol parameter, Pr

61.51

. All existing mapping

parameters will be moved down by one mapping, (i.e. the previous mappings set in
Pr

17.010

and Pr

17.020

will now appear in Pr

17.011

and Pr

17.021

respectively).

Six cyclic words with PPO 4 Word non-cyclic data mapping

shows what

happens to the mapping parameters when the data format is changed from 6 cyclic
words (Pr

17.005

=6) to 6 cyclic words with Mode 2 non-cyclic data. (Pr

17.005

=206).

Table 8-6 Six cyclic words with PPO 4 Word non-cyclic data mapping

There are two problems with this setup, the first is that a configuration error will be
raised because PPO 4 Word non-cyclic uses 4 words, so with the 6 words of cyclic data
mapped, the number of mappings exceed the number specified (6). The second
problem is that the user defined mappings (Pr

17.012

and Pr

17.022

) are lost when the

SI-Interbus is re-initialised. This is because there is insufficient mappings available to
move the user defined channel into.

To maintain all mappings when adding the PPO 4 Word non-cyclic data channel, the
cyclic data format (Pr

17.005

) needs to be set to 210, this adds additional cyclic

channels to accommodate the user defined channel as shown in

words with PPO 4 Word non-cyclic data mapping
