Every analog input module sends, independent from the parameterization,
the measuring value 7FFFh at overflow and 8000h at underflow when
recognizing an error.
At activated
group diagnosis
the group diagnosis-LED (SF) and the error-
LED that is assigned to that channel are blinking.
If you additionally activated the
wire break diagnosis
at current measuring,
a wire break is shown via the error LED assigned to this channel.
At a diagnosis event the CPU interrupts the user program and branches
into OB 82. This OB allows you via according programming to request
detailed diagnostic information by means of the SFCs 51 and 59 and react
to it.
After processing of the OB 82, the processing of the user application is
continued. The diagnostic data are consistent until leaving the OB 82.
As soon as you have activated the diagnostic interrupt release,
record set 0
is transferred to the superordinated system in cause of an error. The
record
set 0
has a fixed content and a length of 4Byte. The content of
record set 0
may be monitored in plain text in the diagnosis window of the CPU.
For the extended diagnosis during run time, you may also evaluate the
record set 1
of 16Byte length via SFCs 51 and 59.
Record set 0 and 1 have the following structure:
Record set 0 (Byte 0 to 3):
Byte Bit 7 ... Bit 0 Default
0 Bit 0: Error in module
Bit 1: reserved
Bit 2: External error
Bit 3: Channel error
Bit 4: external voltage supply missing
Bit 6, 5: reserved
Bit 7: Wrong parameters in module 00h
1 Bit 3 ... 0: Module class
