AS Interface Master
The 75x-655 AS-I Master Module connects AS-Interface systems to a higher-level fieldbus.
The module acts as a Master for the AS-Interface and as a slave for the fieldbus.
The 75x-655 AS-I Master Module is an M4 master in accordance with the AS-Interface V3.0 Specification.
This means:
- up to 62 AS-Interface slaves can be connected per AS-I line,
- the transfer of analog signals is integrated in the Masters and
- support of all slave profiles in accordance with V3.0 and combined transaction types 1 to 5 and acyclic write and read actions.
The AS-I functions are provided both cyclically and acyclically via the fieldbus.
In cyclic data transfer, up to 32 bytes of I/O data are transferred for the AS-I line binary data. Free cyclic process image areas can be mapped with analog values. Furthermore, analog signals and all other commands and data of the new AS-I specification can be transferred in a management channel via the fieldbus.
Diagnostics, which go far beyond the AS-I specifications, simplify the detection of both sporadic configuration errors and AS-I communication interferences. An auto-installation mode allows an AS-Interface network to be created via sequential slave installation, with no addressing tool required.
Both signal transmission and operating status, as well as trouble-free internal data bus communication are indicated via LEDs.
