1.2.3.5 Commissioning
ƒ Settings in or at the module:
– PROFIsafe target address switch
ƒ Required settings in the basic device:
– C00214, type of safety module
ƒ Integration of the SM300 into the drive application
ƒ During commissioning and after the replacement of a module it is vital
to check the safety function.
