AS?Interface network topologyAS?Interface is a single master system. A communications processor (CP 343?2 P), which controls the process or field communication as a master, is used for central application with SIMOTION C or distributed applications over SIMATIC ET 200M. The DP/AS?Interface Link 20E and DP/AS?Interface Link Advanced are used to establish a direct connection between ASInterface and PROFIBUS DP. IE/AS?Interface Link PN IO can also be used to connect AS?Interface to PROFINET. The gateways enable AS?Interface to be used as a subnet for PROFIBUS DP or PROFINET on SIMOTION. Up to 62 slaves can be operated on the AS?Interface. SIMOTION supports all digital and analog AS?Interface slaves (with Analog Profile 7.3 and higher). The maximum extension of an AS?Interface network is 200 m (656 ft) (with AS?i extension plug) or 100 m (328 ft) (without AS?i extension plug). This length can be increased with the help of repeaters. The following AS?Interface masters are available for SIMOTION:
DP/AS?Interface Link Advanced and IE/AS?Interface Link PN IO support particularly easy diagnostics and commissioning on site over the integrated pixel graphics display and control keys or over the web interface using a standard browser. The modules operate in compliance with the latest AS?i specification 3.0 and therefore also support the operation of digital A/B slaves with 4 inputs and 4 outputs as well as analog A/B slaves. If the optional C?PLUG is used, modules can be replaced without the need to set PROFIBUS or Ethernet addresses. The SCOUT command library contains standard functions for easy handling of the AS?Interface components, e.g.
