7.4.8 Control Messages
In the course of system control, the device generates several messages that docu-
ment the process. For example, messages may be given to report the end of a com-
mand or provide the reason for a command denial.
7.4.9 Other Commands
The device is equipped with a serial interface for connection to the System (SCADA)
interface. From there, the device can receive standardized commands (according to
the supported protocol) and transmit them to the respective switching devices, or ac-
tivate internal functions, e.g. block inputs/outputs or set tags (manual overwrite), or re-
lease processing of functions in the CFC. This command processing is determined
during project planning and configuration of the matrix.
