4.20 Application NoteImportant: The configuration software incorporates Reference Signals that represent the state ofcontroller outputs, input devices and both Function and Logic Blocks. A Safety Output reference signalcan be used to control another Safety Output. In this type of configuration, the physical On state of thecontrolling Safety Output is not known. If the Safety Output On state is critical for the applicationsafety, an external feedback mechanism is required. Note that the safe state of this controller is whenthe outputs are turned Off. If it is critical that Safety Output 1 is On before Safety Output 2 turns On,then the device that is being controlled by the Safety Output 1 needs to be monitored to create an inputsignal that can be used to control Safety Output 2. The Safety Output 1 reference signal may not beadequate in this case.Figure 55 on page 63 shows how one Safety Output can control another Safety Output. When Manual Reset M0:MR1 ispressed, it turns On Safety Output M0:SO2, which, in turn, turns On Safety Output M0:SO1.Figure 55. Safety Output controlled by another Safety Output4.21 SC-XM2 Drive and SC-XMP2 Programming ToolThe SC-XM2 drive is used to store a confirmed configuration. The configuration can be written directly by the SafetyController, when the drive is plugged in to the micro-USB port (see Configuration Mode on page 65), or via the SC-XMP2Programming Tool using only the PC Interface without the need to plug in the controller.Important: Verify that the configuration that is being imported to the controller is the correctconfiguration (via the PC Interface or writing on the white label on the SC-XM2 drive).Click to access the programming tool options:• Read—reads the current controller configuration from the SC-XM2 drive and loads it to the PC Interface• Write—writes a confirmed configuration from the PC Interface to the SC-XM2 drive• Lock—locks the SC-XM2 drive preventing any configurations from being written to it (empty drive cannot belocked)NOTE: You will not be able to unlock the SC-XM2 drive after it has been locked.XS/SC26-2 Safety Controller63
