•
The
serial programming interface
, (RS-232C with RJ11 socket) enables
convenient projection and programming of the AS-i masters and the PLC via a
personal computer with a transmission rate of up to 115 kBd.
•
With the optional
Ethernet programming interface
, (10/100 MBd, twisted
pair), the unit can, in addition to even faster programming and diagnosis, also
be networked to other controllere devices.

configuration data of the slaves. These data are summarised in several data fields
and can be accessed via standard IEC addresses (
