Because the PED channel has a max length of 8 byte, it is not possible to read all listed objects simultaneously. This means you
need to make an appropriate selection.
Setting the PED
!
via the object "Process Input Data Description",
or
!
via the COMPAX parameters P135, P136, P137, P138 (corresponds to the object PED_INI).
You may place each of the named objects on the PED channel according to its required bytes.
Set the corresponding COMPAX parameter to the value given for the respective object (see table above).

Ensure that there is no double assignment in the PED channel.
Double assignment occur when e.g. LAGE_IST is on PED1 - PED4 and a further assignment of PED3 (5) is undertaken
via P137.
The proper action in this case would be: POSITION_ACTUAL to PED1 - PED4 using P135 = 6317056 and P136 = P137
= 0!
