11.1.3.2 ASi profiles
Rapid Link 5 has the ASi profile S-7.A.E.
Due to the possible differences in ASi profiles, the master (gateway) must
perform a new initialization when the RASP5 devices are replaced. For this
the ASi master must be switched to configuration mode. In this mode, the
ASi master detects the type and profile of the connected ASi slaves on the
ASi cable.
The profile is “permanently burned in” to the slave modules during manufac-
ture and cannot be changed. As a rule, this configuration mode can only be
activated for an ASi gateway if there is no communication with the gateway.
11.1.4 Gateway
The gateway establishes the connection to the field bus and as the master
handles all communication in the AS-Interface line.
11.1.5 Cable length
The maximum cable length is 100 m in all segments of the ASi circuit.
The distance between an ASi gateway and an ASi slave of the network can
be extended by two repeaters of 100 m each to a maximum of 300 m.
11.1.6 Addressing
Every slave must be assigned an address before data can be transmitted
between the AS-i-/DP gateway and the Rapid Link devices. Rapid Link
devices have a default address of 0.
AS-i slaves can be assigned an address as follows:
• offline: Addressing with the handset
• online: Addressing via the ASi/DP gateway
The addresses that can be assigned are 1A to 31A and 1B to 31B
(on AS-i
version 2.1 and higher). The slaves’ addresses do not have to be
consecutive.

REPLACEMENT OF THE DEVICES
If you are replacing the devices, please contact the manufac-
turer of the PLC used to ensure correct reinitialization.

are using.
