7.13.14 Interrupts in PROFIBUS
De󹪝nition
The interrupt section of the device diagnostics provides information on the type of interrupt and
the cause leading to an interrupt being triggered. The interrupt part comprises a maximum of 48
bytes.
Position in the diagnostic frame
The position of the interrupt part is after the channel-related diagnostics or after the
identi󹪝cation-related diagnostics (for STEP 7).
Example: If three channel-related diagnostics are present, the interrupt part starts from byte 34.
See "Con󹪝guration of device diagnostics for PROFIBUS (Page 202)".
In the event of an interrupt, the channel-speci󹪝c diagnostics are shortened in favor of the
interrupt information.
Contents
The content of the interrupt function depends on the type of alarm:
In the case of diagnostic interrupts, 4 bytes of interrupt header and up to 44 bytes of additional
interrupt information (diagnostic data record 1) for SIMATIC S7 are sent.
For hardware interrupts the length is 4 bytes interrupt header and 4 bytes interrupt state
information.
For pull/plug interrupts, the length is 4 bytes of interrupt header and 5 bytes of additional
interrupt information.
For update interrupts the length is 4 bytes interrupt header and 2 bytes additional interrupt
information.
The meaning of these bytes is described on the following pages.
