ID OUTPUT WORD Logical start address of the PNIO
component that triggers the alarm
(module or submodule).
For an output module, bit 15 is set
(example of output address 5:
ID:=DW#16#8005).
For a mixed module, the lower of the
two addresses is specified.
LEN OUTPUT INT Length of the received alarm
information (AINFO)
MODE IN_OUT DWORD 0 Reserved
TINFO IN_OUT ANY (as
VARTYPE
, BYTE,
WORD
and
DWORD
are
permitted)
The address of the data
area points to one of the
alternatives:
 Memory bit area
 Data block area
The length of the ANY
pointer must be >= 32
bytes.
task information
Destination area for the alarm
management information.
The error OB start information (OB
header = byte 0...19 of TINFO) is
reproduced as far as possible by the
CP firmware.
