Decoding state
Module 20
The module indicates the state of the decoding and of the automatic decoder configuration.
Module 20 must not be used in connection with Modules 21 to 27, because the status infor-
mation for modules 21 to 27 is not consistent or synchronous.

Decoding Result
Modules 21 to 27
The following describes various modules for the output of decoding results. They have the
same structure but different output lengths. The PROFIBUS module concept does not cater
for modules of variable data length. Accordingly, the modules are to be regarded as alter-
natives.
The module defines the transfer of the actually decoded reading results. The data are trans-
mitted consistently over the entire range. If one of the modules 21 to 27 is used, the status
information of the selected module must also be used. The modules only work consistently
or synchronously in themselves.
