0 Description
1 Bit 0: Module fault, i.e. an error was detected
Bit 1: Internal error in the module
Bit 2: External error, module no longer responsive
Bit 3: Channel fault in module
Bit 0 to Bit 3: Module class:
0100 for the IM 152-1DP; set with message for time
stamping or self-diagnostics
1001 for one electronic module: as of byte x+8
Bit 4: Channel information available
Bit 5: User information available

1 0 Description
55 : Self-diagnosis
H
Length of each channel-specific diagnostic informa‐
tion in bits
Number of channels per module
Bit 0: Diagnostic event an channel 0 of the module
Bit 1: Diagnostic event on channel 1 of the module (in
case of redundancy)
1 0 Error type on channel 0: Byte x+12 to x+19
The corresponding error type number of the channel-
related diagnostics is placed in brackets.
You can find additional notes on the meaning and
solution in section "Error types of the electronic mod‐
ules with PROFIBUS (Page 209)".
