Safety and Standard Function Blocks

A host of ready-to-use and tested safety function blocks enable the implementation of a wide range of safety applications with only one device, thus considerably reducing stock-keeping costs. Safety also comes with the tried and tested standard function blocks of the 800 series and thus allows general control tasks to be processed conveniently as well as providing extensive machine diagnostics options.
