4.5 Fault information
A distinction is always made between two types of faults:
block faults and transmission faults.
Block faults (e.g. incorrect logic address, incorrect hardware
configuration, etc.) are caused by the relevant system func
tion blocks used SFC14/SFC15, SFC58/SFC59, SFB52/SFB53
or SFC24 and shown at the output RET_VALUE. The fault code
can be found in the
STEP 7 help. If a block fault occurs, the
block will be exited with the ENO bit = 0.
Transmission faults arise as a result of incorrect parameter
data (e.g. non−existent PN U, incorrect parameter length when
writing, non−existent subindex, etc.).
Transmission faults are shown with the bit Fault.
With the aid of the
value of Value_RD the fault can be evalu
ated accordingly Tab.4/10.
