Interrupt status
3-28
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 the interrupt type, the interrupt section has the following
structure:
Byte Element
x...x+3 Interrupt status Contains information about the interrupt type
x+4...x+19 Diagnostic
interrupt
x+4...x+7 Hardware
interrupt
If there is a diagnostic event for 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:
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
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:
Bit 2: 0 (fix)
Bit 7 ... 3: interrupt sequence number 1 ...32
Description
The 16Byte correspond to the record set 1 of
the CPU diagnostic
The 4Byte are module specific and are
described with the according module.
0000001: Diagnostic interrupt
0000010: Hardware interrupt
00: Hardware interrupt
01: Diagnostic interrupt
10: Diagnostic interrupt
11: reserved
