4 Data Descriptions
4.1 Machine data
10098 $MN_PROFISAFE_IPO_TIME_RATIO
MD number Factor for PROFIsafe communications cycle
Default: 1
Change becomes effective after RESTART
Data type: DWORD
Meaning Relationship between the interpolator clock cycle and the clock cycle in the
communications with PROFIsafe I/Os modules. In the resulting time grid, OB40 on the
PLC side is initiated from the NCK side to enable communication between F master and F
slaves.
The value obtained for the communication clock cycle from this MD and the set IPO cycle
must not be greater than 25 ms.
Special cases, errors
Corresponds with ...
10099 $MN_INFO_PROFISAFE_CYCLE_TIME
MD number PROFIsafe communications clock cycle
Default: 0.000
Changes effective after POWER ON
Data type: DOUBLE
Meaning Shows the time grid for communications between F master and F slaves. The value is
obtained from the interpolator clock cycle and MD $MN_PROFISAFE_IPO_TIME_RATIO.
For display purposes only - cannot be written into.
Special cases, errors
Corresponds with ...
10385 $MN_PROFISAFE_MASTER_ADDRESS
MD number PROFIsafe address of F master
Default: 0
Change becomes effective after RESTART
Data type: DWORD
Meaning Defines the PROFIsafe address for the F master NCK/PLC. Used to uniquely assign an F
master to an F slave. This parameter must be entered in accordance with the
"F_Source_Address" parameter set in S7-ES for the F slaves. An attempt to establish
communications is only made for F slaves where this address has been entered.
Special cases, errors
Corresponds with ...
10386 $MN_PROFISAFE_IN_ADDRESS
MD number PROFIsafe address of an input module
Default: 0
Change becomes effective after RESTART
Data type: DWORD
Meaning Defines the PROFIsafe address of a PROFIsafe input module
Special cases, errors
Corresponds with ...
10387 $MN_PROFISAFE_OUT_ADDRESS
MD number PROFIsafe address of an output module
Default: 0
Change becomes effective after RESTART
Data type: DWORD
Meaning Defines the PROFIsafe address of a PROFIsafe module
Special cases, errors
Corresponds with ...
