2.7 AS-i Master for PC-AT

CP 2413 (Standard AS-i Master)

The CP 2413 (AS-i standard master) allows the attachment of AS-Interface to

PCs.

The hardware of the AS-i master is implemented as a short PC-AT card. Up to four

AS-i master CPs can be operated at the same time in one PC. This means that the

Siemens AS-i PC master is also suitable for complex control tasks. The firmware

running on the PC master is loaded when the host is started up.

An operating and demonstration program is available which provides the current

status of the slaves on the cable and permits simple operation of the slaves. This

program can also be used for diagnostic purposes; it also allows the programming

of the addresses of AS-i slaves.

Since not only the AS-i master card can be operated in a PC, but also PC

interfaces for the Industrial Ethernet and PROFIBUS bus at the same time, the

data supplied by the AS-i slaves can also be made available to other stations in the

network.
