IE/AS‑i LINK PN IO (single master and double master)

The AS-Interface can be integrated into the SIMATIC PCS 7 process control system as follows:

• Direct connection on the PROFIBUS DP via DP/AS-i LINK Advanced (AS-i single or double master)
• Connection via a CP 343-2 or CP 343-2P AS-i master module in an ET 200M remote I/O station on the PROFIBUS DP
• Direct connection on the PROFINET IO via IE/AS‑i LINK PN IO (AS‑i single or double master)

AS‑i integration in SIMATIC PCS 7 via PROFINET IO

System components

The basic components of a system installation are:

• AS-Interface master (alternatives):
  • DP/AS-i Link Advanced (AS-i single or double master)
  • CP 343‑2 or CP 343‑2P (both can be operated in an ET 200M remote I/O station)
  • IE/AS-i LINK PN IO (AS‑i single or double master)
• AS-Interface block library for SIMATIC PCS 7 (add-on product, see catalog "Add-ons for SIMATIC PCS 7", section "Libraries/Blocks/Tools")
• AS-Interface shaped cable (use of round cable also possible if preferred)
• Modules for connecting standard sensors/actuators
• Power supply unit for powering the slaves
• Actuators and sensors with an integrated slave ASIC
• Address programming device for setting the slave address

AS‑i slaves

You can use all digital AS‑i standard slaves as well as digital AS‑i A/B slaves in accordance with the AS‑i specification V3.0. Analog AS-i slaves can also be integrated via the DP/AS‑i Link Advanced or the IE/AS‑i LINK PN IO.

Note:

The CP 343‑2 and CP 343‑2P AS-i masters transfer I/O data from AS‑i slaves with a B address via data records and not via the cyclic process image (partition). To prevent delays in the communication process of the driver blocks for B slaves, it is recommended to avoid using AS-i slaves with B addresses for SIMATIC PCS 7 configurations with CP 343-2 or CP 343-2P.
