Interrupts
Definition
The interrupt section of the slave diagnostics provides information on the type of interrupt
and what triggered it. The interrupt part consists of a maximum of 20 bytes.
Position in the diagnostics frame
The interrupt section comes after the channel-specific diagnostics (only in DPV1 mode).
Data sets
The diagnostic data of a motor starter can be up to 16 bytes in length and is located in data
sets 0 and 1:
● Data set 0 contains 4 bytes of diagnostic data describing the current status of an
automation system.
● Data set 1 contains the 4 bytes of diagnostic data that are also contained in data set 0
and 12 bytes of module-specific diagnostic data.
DS0 and DS1 can be read out with SFC 59 "RD_REC."
Contents
The contents of the interrupt information depend on the interrupt type:
● In the case of diagnostics interrupts, diagnostic data set 1 (16 bytes) is sent as the
interrupt status information (starting at byte x + 4).
