  • openSAFETY manager for up to 280 SafeNODEs
  • Flexibly programmable using Automation Studio / SafeDESIGNER
  • Innovative management of safe machine options (SafeOPTION)
  • Parameter and configuration management

The module is equipped with SafeLOGIC functionality that allows it to safely execute applications designed in SafeDESIGNER. The module can be used in safety-related applications up to PL e or SIL 3.

In addition, the module coordinates the safety-related communication of all modules involved in the application. In this context, the module also monitors the configuration of these modules and carries out autonomous parameter downloads to the modules whenever necessary. This guarantees a consistent and correct module configuration in the network from a safety standpoint in all scenarios involving module replacement and service. These services are performed by the SafeLOGIC controller.

Mandatory Accessories
X20MK0223 X20 SafeKEY, 8 MB, for the X20SL81xx series, exclusively for mapp Safety, range of license functions determined via a package-based licensing model or via Technology Guarding in Automation Runtime
X20MKXXXX.XXX.XXX X20 SafeKEY, for X20SL81xx series, for legacy safety and mapp Safety. The available range of functions is defined by "Safety Technology Guarding". Licenses are stored on a SafeKEY dongle. The range of functions required for the application must be compiled by selecting the available technology functions in the X20MK configurator. Each solution is delivered exclusively as a set consisting of the SafeKEY and the activated licenses for the selected technology functions.
