Parameter P711 / P696 = 2
The useful data (PPO) sent to the DP master via the standard cyclical
channel MSCY_C1 are entered into the diagnostics buffer.
PPO-type = 1
Four words are sent, PKW part plus status word 1 (ZSW1) and the main
actual value (HIW). The PKW part is stored, beginning with the PKE, in
parameter r732.9 and ZSW1 as well as the HIW from parameter r732.13
onwards (high part at the least significant address).
In the following example, the reply (to the DP master) to the WRITE
request in example 1 is shown in parameter P443 with the value "3002".
The status word is returned by the converter with 4331
given as the actual value.
The values in r732 are displayed in Motorola format, i.e. high-byte and
low-byte are shown interchanged in relation to what is displayed in the
other parameters.
