9.2 Status info
The status info is a coded piece of information on the current status of
a sensor. Each sensor sends this status info to the controller. The sta-
tus info of sensors consists of 32 bits, each of which can have the value
0 or 1.
Status info,
general structure
The bits 0 - 15 are reserved for general information.
The bits 16 - 21 are reserved for internal service information.
You obtain the status info:

components menu (see system operating manual)
 by an automated query
– from a superordinate process control (e. g. when connected to
the Profibus)
– from the IQ Data Server (see IQ
