device manual AS-i DP - Gateway
2 The AS-i DP-Gateway family
The AS-i DP -Gateway contain 1 (AC1335) or 2 AS-i masters (AC1326) having the AS-i Association’s
advanced specification 2.1. This new specification brings the following features to the AS-i DP -
Gateway family:
a single slave can now be replaced with a pair of A/B slaves allowing connection of up to 62 (A/B)
slaves per master,
the new profiles S-7.3 and S-7.4 enable "plug and play" operation of analogue slaves
the introduction of periphery fault flags brings a better diagnosis of I/O modules in case of possible
erroneous connections
Detailed system diagnosis is made possible by the text/graphics-display of the DP-Gateway. The
operation of the four buttons can be learned intuitively. The two language capability of the text display
is especially useful for those who export their applications to a foreign. An intelligent message
management system generates priority controlled messages ensuring their display in order of
importance.

The serial programming interface of the AC1326 (RS232 C with RJ45 socket) can be used exclusively
to update device firmware.
The Field bus interface allows for the connection to a field bus system such as Profibus-DP thereby
facilitating operation as a very easy to use gateway.
