Safety controller Adding the safety controller In the case of the parent/child controller topology, the safety controller is inserted directly below the standard controller or in the fieldbus. This is
Safety Logic The Safety Logic node exists for reasons of symmetry to the standard controller. It identifies the device as a PLC, but has no additional meaning in the safety controller. The Safety Logi
Application (Safety) object The objects relevant for the safety controller and its programming are located below the safety controller. Directly below them is always the symbolic node point Safety Log
Safety POUs POUs (Program Organization Units) are the programming objects of CODESYS Safety Extension which are declared as either programs ( PROGRAM ) or function blocks ( FUNCTION_BLOCK ). The follo
