4-212 SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
10098
MD number
$MN_PROFISAFE_IPO_TIME_RATIO
Factor for PROFIsafe communications cycle
840D
Default: 1 Min. input value: 1 Max. input value: 25
Change becomes effective after RESTART Protection level (R/W) 7/2 Unit: -
Data type: DWORD Applies from SW 6.3
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.

MD number
$MN_INFO_PROFISAFE_CYCLE_TIME
PROFIsafe communications clock cycle
840D
Default: 0.000 Min. input value: - Max. input value: -
Changes effective after POWER ON Protection level (R/W) 7/2 Unit: s
Data type: DOUBLE Applies from SW 6.3
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.

10385
MD number
$MN_PROFISAFE_MASTER_ADDRESS
PROFIsafe address of F master
840D
Default: 0 Min. input value: 0 Max. input value: 50FA7DH
Change becomes effective after RESTART Protection level (R/W) 7/2 Unit: -
Data type: DWORD Applies from SW 6.3
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.

MD number
$MN_PROFISAFE_IN_ADDRESS
PROFIsafe address of an input module
840D
Default: 0 Min. input value: 0 Max. input value: 5003FFH
Change becomes effective after RESTART Protection level (R/W) 7/2 Unit: -
Data type: DWORD Applies from SW 6.3
Meaning Defines the PROFIsafe address of a PROFIsafe input module
Special cases, errors

10387
MD number
$MN_PROFISAFE_OUT_ADDRESS
PROFIsafe address of an output module
840D
Default: 0 Min. input value: 0 Max. input value: 5003FFH
Change becomes effective after RESTART Protection level (R/W) 7/2 Unit: -
Data type: DWORD Applies from SW 6.3
Meaning Defines the PROFIsafe address of a PROFIsafe module
