AS-i networks can be easily adjusted to system expansions as AS-Interface is accurately matched to the requirements of the lowest field level: Realtime capability, low data volumes and a large number of connected devices – in addition to the already mentioned benefits of freely selectable topology and innovative insulation piercing method.
An AS-i network can be expanded to up to 62 AS-i slaves. In terms of simple I/O modules, this corresponds to a maximum of 992 I/O points, distributed to a bus length of up to 600 m per AS-i network.
Also analog values, e.g. of analog modules or measuring transducers, can be integrated just as easily as digital I/Os. The AS-i master automatically organizes the transfer of all data. This way, a small field bus can be effortlessly expanded and flexibly adjusted to machine or system changes.
