Interrupts

The information in this section is applicable for IM151-1 STANDARD (up to
6ES7 151-1AA04-0AB0), IM151-1 FO STANDARD (up to 6ES7 151-1AB03-0AB0),
IM151-1 HIGH FEATURE:
Definition
The interrupt section of the slave diagnosis provides information on the interrupt
type and the cause that led to the triggering of the interrupt. The interrupt section
consists of a maximum of 48 bytes.
Position in the diagnostic frame
The position of the interrupt section is after the channel-specific diagnosis
(DPV1 mode only).
Example: If there are three items of channel-related diagnostic information, the
interrupt section starts at byte 44.
Data records
The diagnostic data of a module can be up to 44 bytes in length and is located in
data records 0 and 1:
• Data record 0 contains 4 bytes of diagnostic data describing the current status
of a programmable logic controller. Data record 0 (DS0) is part of the header
information of OB 82 (local data bytes 8 to 11).
• Data record 1 contains the 4 bytes of diagnostic data that is also contained in
data record 0 and, in addition, up to 40 bytes of module-specific diagnostic
data.
You can read out data records 0 and 1 (DS0 and DS1) by means of SFC59
"RD_REC".
Contents
The content of the interrupt information depends on the interrupt type:
• In the case of diagnostic interrupts, diagnostic data record 1 ( up to 44 bytes) is
sent as the interrupt status information (as of byte x+4).
• In the case of hardware interrupts, the interrupt status information is 4 bytes in
length.
• With remove/insert interrupts the length of the interrupt status information is
-- 5 byes with IM151-1 HIGH FEATURE
-- 0 bytes with IM151-1 STANDARD (as of 6ES7 151-1AA04-0AB0) and
IM151-1 FO STANDARD (as of 6ES7 151-1AB03-0AB0)
