The
serial programming interface
(RS-232C with RJ11 socket) enables easy 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 device can,
in addition to even faster programming and diagnosis, also be networked to other controllere
devices.

Introduction AS-i data
The AS-i master and the AS-i slaves make a large amount of data available to the user. The user can
request information, such as the status of the master and the configuration data of the slaves. This
data is summarised in several data fields and can be accessed via standard IEC addresses.
