Communication blocks
Function Blocks - FM 458-1 DP 2-13
Edition 12.2004
STA Station address of the slave which had initiated the alarm. Values
of between 1 to 126 are valid values for this address.
(Default: 0)
SLO Slot of the module which initiated the alarm. Values of between 1
and 244 are valid values for the slot data.
(Default: 0)
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.
(Default: 0)
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.
(Default: 0)
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.
(Default: 0)
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) Æ Input module
B#16#55 (55 hexadecimal) Æ Output module
The (present) possible information is available, in a
conditioned form, at outputs IN and OUT.
(Default: 0)
IN
IN=1 Æ Input module has initiated an alarm
IN=0 Æ The alarm was not initiated from an input module
(Default: 0)
OUT OUT=1 Æ Output module had initiated an alarm
OUT=0 Æ The alarm was not initiated from an output module
(Default: 0)
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.
(Default: 0)
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.
(Default: 0)
YYR Year
(specifies in which year the alarm was initiated)
(Default: 0)
YMO Month
(specifies in which month the alarm was initiated)
(Default: 0)
YDA Day
(specifies on which day the alarm was initiated)
(Default: 0)
YHR Hour
(specifies at which hour the alarm was initiated)
(Default: 0)
YMI Minute
(specifies at which minute the alarm was initiated)
(Default: 0)
YSE Second
(specifies at which second the alarm was initiated)
(Default: 0)
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).
(Default: 0)
