What has to be
If the condition to write the position in traversing block 4 is available,
programmed
then the following must occur on the master side

– PKW output signals (PAB 272 – 279) written into
with
AK = 8, PNU = 81, IND = 3, PWE2 = 14586
– Evaluate the PKW input signals (PEB 272 –279)
– If AK = 5, PNU = 81, IND = 3 and PWE2 = 14586 then OK
– If AK = 7,
then evaluate the fault number in PEW 278 (refer to Table 5-31)
