System components

To implement the communication, the following system installation components are available

AS?i Master modules for central control units such as SIMATIC S7, ET 200M/ET 200SP distributed I/O, or routers from PROFIBUS or PROFINET to AS?Interface
Power supply units, if required in combination with a data decoupling module for the power supply to the slaves
AS-Interface shaped cables
Network components such as repeaters and extension plugs (cannot be used for AS-i Power24V)
I/O modules (AS-i slaves) for connection of standard sensors/actuators
Actuators and sensors with integrated AS-i slave
Safe I/O modules (ASIsafe slaves) for transmitting safety-related data through AS?Interface
Addressing units for setting the slave addresses during commissioning

Example of a configuration with the system components

Standard	EN 50295 / IEC 62026?2
Topology	Line, star or tree structure (same as electrical wiring)
Transmission medium	Unshielded twisted pair (2 x 1.5 mm²) for data and auxiliary power
Connection method	Contacting of the AS-Interface cable by insulation piercing method
Maximum cable length	100 m without repeater 200 m with extension plug 300 m with two repeaters in series connection 600 m with extension plugs and two repeaters connected in parallel Larger cable lengths are also possible when additional repeaters are connected in parallel
Maximum cycle time	5 ms in full expansion with 31 standard addresses 10 ms in full expansion with 62 A/B addresses profile-specific for slaves with extended data, e.g. analog slaves
Number of stations per AS-Interface line	up to 62 slaves (A/B technology) integrated analog value transmission
Number of binary sensors and actuators	max. 496 DI/496 DO
Access control	Cyclic polling master/slave procedure cyclic data copying from host (PLC, PC)
Error safeguard	Identification and repetition of faulty message frames
