Siemens SINUMERIK 840D Description Of Functions page 190

3 Safety-Related Functions
3.12 SI I/Os using fail-safe modules connected to PROFIBUS DP (840D from SW 6.3.30)
Further, an attempt is still made to initiate the OB40 interrupt and to maintain
PROFIsafe communications.
The time up to initiating the next OB40 interrupt is displayed in the following
NCK machine data:
•
If the PROFIsafe clock cycle is continuously exceeded and just not
sporadically, then the following alarm is displayed:
•
2.
Assignment: F The NCK machine data is used to parameterize the F master for the F modules
modules to F master assigned to it:
•
•
Index: 0...15
Input format: 0s 00 0a aa
The PROFIsafe address of the F module is the value of the F parameter
defined by HW Config: F_Target_Address (refer below: Example of an
assignment).
Parameterizing errors The following parameterizing errors are detected at run-up and the appropriate
alarms displayed:

SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
MD 10099: $MN_INFO_PROFISAFE_CYCLE_TIME,
(PROFIsafe communications clock cycle)
Alarm: 27256 "PROFIsafe actual cycle time Cycle time [ms] >
parameterized cycle time"
Parameterizing the SPL SGE/SGA interface
MD 10386: $MN_PROFISAFE_IN_ADDRESS[Index],
(PROFIsafe address of an input module)
MD 10387: $MN_PROFISAFE_OUT_ADDRESS[Index],
(PROFIsafe address of an output module)
s: Bus segment (currently only: 5 = DP connection on the PLC side)
-
aaa: hexadecimal PROFIsafe address of the F module
-
Note
1. The PROFIsafe address of an F module can be found under:
HW Config -> Properties dialog box of the F module -> F parameter:
F_Target_Address (e.g.: 1022
Refer to Chapter: Configuring and parameterizing the ET 200S F I/Os
2. The PROFIsafe address of the F modules displayed in the HW Config in
the decimal format must be entered in the hexadecimal format in the
NCK machine data:
• MD 10386: $MN_PROFISAFE_IN_ADDRESS[Index]
• MD 10387: $MN_PROFISAFE_OUT_ADDRESS[Index]
Incorrect bus segment (bus segment <> 5)
-
Incorrect PROFIsafe address error for F master or F module
-
More F modules in the NCK machine data than in the
-
3)
configuration
More F modules in the NCK machine data than assigned as
-
F master in the configuration of the NCK
The PROFIsafe address of an F module does not exist in the

4)
configuration
An F module assigned to the NCK as F master in the
-
configuration has not been entered in the NCK machine data
The module type (input, output) detected in the NCK machine
-
data does not match the configuration
An F module has been parameterized more than once
