The interrupts section of the slave diagnostic provides information on the
type of interrupt and the cause that triggered the input. The interrupt section
has a maximum of 20bytes. A maximum of one interrupt can be used per
slave diagnostic. The interrupt component is always the last part of the
diagnostic frame.
The contents of the interrupt information depend on the type of interrupt:
• In the case of diagnostic interrupts, the diagnostic data record 1 is send
as interrupt information (as of Byte x+4)
• In the case of process interrupts, the additional information is 4bytes
long. These data is module specific and is described at the concerning
module.
If there is a diagnostic event for channel (/channel group) 0 of a module,
there may be a module error as well as a channel error. The entry is made
in this case even if you have not enabled the diagnostic for channel
(/channel group) 0 of a module.
The interrupt section is structured as follows:
Alarm status Byte x ... x+3
Byte Bit 7 ... Bit 0
x Bit 5 ... 0: 010100: Length of the interrupt section incl. Byte x
Bit 6 ... 7: Code for Module-Related diagnostic
x+1 Bit 0 ... 6: Type of interrupt
0000001: Diagnostic interrupt
0000010: Process interrupt
Bit 7: Code for interrupt
x+2 Bit 7 ... 0: Slot of the module that is producing interrupt 1 ... 32
x+3 Bit 1, 0: 00: Process interrupt
01: Diagnostic interrupt
incoming
10: Diagnostic interrupt
outgoing
11: reserved
Bit 2: 0 (fix)
Bit 7 ... 3: Interrupt sequence number 1…32
