Adaptation of the status codes
It is possible to adapt the status codes (e.g. as TwinCAT LED). To do this, the system colors can be
changed with the aid of an SMB command. This change remains in force until the next restart or re-
set. A change of the default colors is indicated by the additional flashing of the white LED.
