Firmware functions of the analog on-board I/O module
Functions of the analog inputs
The 5 inputs of the analog on-board I/O module have the following functions:
You have the option of reassigning parameters for the
analog on-board I/O module in RUN (for example,
measuring ranges of individual channels can be modi-
fied in RUN without affecting the other channels).
• Chapter Parameters of the ana-
log on-board I/O (Page 122)
• Chapter Parameter assignment
and structure of the parameter
data records of the analog on-
board I/O (Page 166)
Support of the value status
(Quality Information, QI)
Value status = 1 ("Good") indicates that the value of
the assigned input at the terminal is valid.
Value status = 0 ("Bad") indicates that the read value
is not valid.

log on-board I/O (Page 114)
Functions of the analog outputs
The 2 outputs of the analog on-board I/O module have the following functions:
You have the option of reassigning parameters for the
analog on-board I/O module in RUN (for example,
output ranges of individual channels can be modified
in RUN without affecting the other channels).

log on-board I/O (Page 122)
• Chapter Parameter assignment
and structure of the parameter
data records of the analog on-
board I/O (Page 166)
Support of the value status
(Quality Information, QI)
Value status = 1 ("Good") indicates that the process
value specified by the user program is correctly out-
put at the terminal.
Value status = 0 ("Bad") indicates that the process
value output at the hardware output is incorrect.
