The interrupt section of the slave diagnostic shows informations about
interrupt type and cause. It consists of max. 20Byte. For every slave
diagnostic max. 1 interrupt can be send. The interrupt section is always the
last part of the diagnostic telegram if activated it in the parameterization.
Depending on t he interrupt type, the interrupt section has t he following
structure:
Byte
Element
Description
x...x+3
Interrupt status Contains information about the interrupt type
x+4...x+19 Diagnostic
interrupt
The 16Byte correspond to the record set 1 of
the CPU diagnostic
x+4...x+7
Hardware
interrupt
The 4Byte are module specific and are
described with the according module.
If there is a diagnostic event for channel/group 0 of a module, there may be
a module error as well as a channel er ror. 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:
Interrupt status Byte x ... x+3
Byte Bit 7 ... Bit 0
x
Bit 5 ... 0: 010100: Length of the interrupt section incl. Byte x
Bit 7 ... 6: 00 (fix) Code for Module-Related diagnostic
x+1
Bit 6 ... 0: Type of interrupt
0000001: Diagnostic interrupt
0000010: Hardware 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: Hardware interrupt
01: Diagnostic interrupt
incoming
10: Diagnostic interrupt
outgoing
11: reserved
Bit 2: 0 (fix)
Bit 7 ... 3: interrupt sequence number 1 …32
