$MN_SAFE_SPL_STOP_MODE
Selects the stop response when errors are detected in the crosswise data comparison of NCK
and PLC-SPL
3: Stop D
4 Stop E
When the value 4 is entered in this MD (Stop E) without enabling the external Stop E in all
axes with SI function enable signals (MD36901 $MA_SAFE_FUNCTION_ENABLE not equal
to 0) results in Alarm 27033 with reference to this MD.
To remedy this, either parameterize STOP D or set bit 4 and bit 6 in MD36901
$MA_SAFE_FUNCTION_ENABLE for all of the axes involved.
If this MD is set to 4, then DB18.DBX36.1 (STOP E) must also be set to 1 in order to commu‐
nicate this parameterization to the PLC. For a different parameterization, Alarm 27090 is out‐
put.
$MN_PROFISAFE_IPO_TIME_RATIO
Factor PROFIsafe communications clock cycle time
Min. input limit: 1
Ratio between PROFIsafe communication and interpolation clock cycle. The actual PROFI‐
safe communication clock cycle is the product from this data and MD10071 $MN_IPO_CY‐
CLE_TIME and is displayed in MD10099 $MN_INFO_PROFISAFE_CYCLE_TIME. In this
clock cycle, OB40 on the PLC side is initiated from the NCK to enable communication between
the F-master and F-slaves.
The PROFIsafe communications clock cycle may not be greater than 25 ms.
$MN_INFO_PROFISAFE_CYCLE_TIME
PROFIsafe communications clock cycle time
Min. input limit: -
Display data:
Displays the maximum time grid for communications between an F-master and F-slave. PRO‐
FIsafe communication via the OB40 in the PLC uses this time grid.
The value is obtained from the interpolator clock cycle and MD10098 $MN_PROFI‐
SAFE_IPO_TIME_RATIO.
When the set communication clock cycle is exceeded, this is also displayed here.
In the case of an incorrect parameterization (communication clock cycle exceeds the maxi‐
mum value of 25.0 ms) then the maximum value that can be set is displayed.
