ET 200C Distributed I/O Station
EWA 4NEB 812 6119-02b
In order to request station diagnostics for an ET 200C station, you must call
the FB IM308C function block (FB 192) with the function FCT = SD.
The FB IM308C places the station diagnostics in the S5 data block of the
CPU opened with the FM IM308C call (data block or marker area). It is im-
portant to define two memory areas of equal size, in order to ensure that lim-
it-value alarms and diagnostics alarms do not overwrite each other
(see Figure 8-1).

Diagram Illustrating How Station Diagnostics is Requested with
FB IM308C
FB IM308C and its use relate to general access to diagnostics data of the
IM 308-C and are described in detail in the manual ET 200 Distributed
I/O System (Order No. 6ES5 998-3ES12).
The example below illustrates how to call station diagnostics with the aid of
the FB IM308C and store the information in a data block.
The example is followed by a description of how station diagnostics is
evaluated. This description is based on the assumption that the diagnostics
data is stored in a data block.
