Safety engineering
Integration into the application
136 Firmware 1.37 - 09/2006 L
8.1 Integration into the application
If a safety function is required, the safety engineering activates a corresponding safe
monitoring function. The standstill function, however, is only executed directly in case of
the function "Safe torque off" (STO). In case of the other safety functions an action of the
controller is required, which is safely monitored. The implementation of the corresponding
action (e.g. braking, braking to standstill, holding of the standstill position) must be carried
out by the application.
"LS_SafetyModule" system block
For the transmission of the control and status information from the safety module to the
application the LS_SafetyModule system block is provided in the function block editor of
the »Engineers«.
Basic function "Limiter"
Furthermore the LS_Limiter system block which contains the basic function Limiter" is
provided in the function block editor for the connection of safety engineering to the
application.
(C 200)
The basic function "Limiter" provides a parameter setting surface in the »Engineer« for a
comfortable setting of limit positions, limited speeds and limit values and enables the
drive to braked selectively after request through the safety module.
General procedure
1. Activation of the safety function on the safety module (e. g. SS1 - safe stop 1).
Monitoring starts.
2. The safety module informs the controller via a control word that the safety function
has been activated.
3. The application evaluates the control word and starts the required motion sequence
(e.g. braking).
8.2 Selecting the required safety module
The safety module expected by the application and the controller is selected in C00214.
r In the »Engineer« this setting is carried out automatically by assigning the device
module to the controller, i.e., the »Engineer« sets C00214
automatically according to
the safety module selected.
r If the safety module selected in C00214
does not correspond to the safety module type
connected, an error will be activated.
