With the channel-related diagnostic you gain detailed information about the
channel error within a module. For the usage of the channel-related
diagnostic you have to release the diagnostic interrupt for every module via
the parameterization. The channel-related diagnostic can be activated via
the parameterization and has the following structure:
Channel-related diagnostic
Byte Bit 7 ... Bit 0
X Bit 5 ... 0: ID number of the module that delivers the channel-
specific diagnostic (000001 ... 011111)
e.g.: Slot 1 has ID no. 0
Slot 32 has ID no. 31
Bit 7, 6: 10 (fix) Code for channel-related diagnostic
X+1 Bit 5 ... 0: Number of the channel or the channel group that
delivers the diagnostic (00000 .... 11111)
Bit 7 ... 6: 01=Input Module
10=Output Module
11=In-/Output Module
X+2 Bit 4 ... 0: Error messages to Profibus standard
00001: Short circuit
00010: Undervoltage (Supply voltage)
00011: Overvoltage (Supply voltage)
00100: Output Module is overloaded
00101: Temperature rise output Module
00110: Open circuit sensors or actors
00111: Upper limit violation
01000: Lower limit violation
01001: Error - Load voltage at the output
- Sensor supply
- Hardware error in the Module
Error messages - manufacturer-specific
10000: Parameter assignment error
10001: Sensor or load voltage missing
10010: Fuse defect
10100: Ground fault
10101: Reference channel error
10110: Hardware interruptlost
11001: Safety-related shutdown
11010: External fault
11010: Indefinable error - not specified
Bit 7 ... 5: Channel type
001: Bit
010: 2 Bit
011: 4 Bit
100: Byte
101: Word
110: 2 Words
The maximum number of channel-related diagnostic is limited by the total
length of 58Byte for diagnostic. By de-activating of other diagnostic ranges
you may release these areas for further channel-related diagnostic. For
each channel always 3Byte are used.
