How the DP/AS Interface Link 20 Works
With the DP/AS-interface link 20, up to 248 binary elements are accessible to a DP
master on the AS-interface (124 inputs and 124 outputs). You can therefore
combine the advantages of PROFIBUS-DP and AS-interface in a plant. The
DP/AS-interface link 20 can be used in the AS-interface standard mode (M2). In
this mode, the data bits of the slaves are accessible. The following master calls are
supported.
S
Change address
S
Write parameters
S
Read configuration data
S
Set configuration mode
S
Configure actual configuration
Parameter Assignment
The DP/AS-interface link 20 is supported by STEP 7 (V4.1 and higher) and COM
PROFIBUS (V 3.2 and higher). The type and GSD files are shipped along with the
manual. On the AS-interface side, no special configuration is necessary; the
AS-Interface segment can be put into operation without PROFIBUS.
