I/O
STA Station address of the slave which had initiated the alarm. Values
of between 1 to 126 are valid values for this address.
SLO Slot of the module which initiated the alarm. Values of between 1
and 244 are valid values for the slot data.
SUB Sub-module of the module which initiated the alarm. Values of
between 1 and 31 are valid values for the sub-module data.
A value of 0 means no sub-module.
SBN Sub-network to which the module, which initiated the alarm, is
connected. Values of between 1 and 255 are valid values for the
sub-network data. The number for the sub-network can be taken
from the properties dialog box in NetPro or HW-Config.
EVC
This output corresponds to the local data variables
OB40_EV_CLASS of the OB40 for a SIMATIC-S7. A value of
B#16#11(11 hexadecimal) means that the alarm is active.
IOF
This output corresponds to the local data variables
OB40_IO_FLAG of the OB40 for a SIMATIC-S7.
The significance is as follows:
B#16#54 (54 hexadecimal)
B#16#55 (55 hexadecimal)
The (present) possible information is available, in a
conditioned form, at outputs IN and OUT.
IN
IN=1 Input module has initiated an alarm
IN=0 The alarm was not
OUT OUT=1 Output module had initiated an alarm
OUT=0 The alarm was not initiated from an output module
MDL This value outputs the logical basis address of the module.
The value corresponds to the local data variables
OB40_MDL_ADDR of the OB40 for a SIMATIC-S7.
PAD This value supplies additional information about the cause of the
process alarm. The value corresponds to the local data variables
OB40_POINT_ADDR of the OB40 for a SIMATIC-S7. Additional
information about this is provided in the SIMATIC documentation.
YYR Year
(specifies in which year the alarm was initiated)
YMO Month
(specifies in which month the alarm was initiated)
YDA Day
(specifies on which day the alarm was initiated)
YHR Hour
(specifies at which hour the alarm was initiated)
YMI Minute
(specifies at which minute the alarm was initiated)
YSE Second
(specifies at which second the alarm was initiated)
QTS Block output QTS is used to display whether the block is
operating error-free (QTS = 1) or was de-activated after a
communications error message was entered (QTS = 0).
