Status Byte - Siemens Pointek CLS200 Operating Instructions Manual

9.2.1

Status byte

The status byte is a standardized code returned by a PROFIBUS slave on every bus scan, along
with the main process variable (output of the Analog Input Function Block).
• The status code indicates whether the process variable is valid or not.
• It also indicates other process-related information.
Status codes
The codes for the Status bytes are listed in the following tables. Possible causes for an error
are shown, along with measures to correct it.
If the language selected for the display is numeric, a status code will be displayed. If any
other language has been selected, a status description will be displayed.
Note
For more detail, please consult the PROFIBUS PA User and Installation Guideline (order
