AS‑Interface block library for SIMATIC PCS 7 in the CFC chart

The AS‑i function block library for PCS 7 is integrated in the SIMATIC PCS 7 process control system and expands it for integration of the AS‑Interface system.

As the result, the advantages of AS‑Interface such as the considerable reduction of wiring outlay for distributed actuators/sensors and very simple installation can also be used in a system based on PCS 7.

The library contains modules for accessing the I/O data of AS‑i slaves, modules for diagnostics of the AS‑i system, and a faceplate for the PCS 7 Maintenance Station.

Supported AS-Interface modules

The AS‑Interface block library for PCS 7 can be used with the following AS‑i master and link modules:

• CM AS-i Master ST (in ET 200SP station) 3RK7137-6SA00-0BC1 (engineering software V9 and V8.1 only)
• CP 343-2 (in ET 200M station) 6GK7343-2AH01-0XA0
• CP 343-2P (in ET 200M station) 6GK7343-2AH11-0XA0
• DP/AS-i Link Advanced single master 6GK1415-2BA10
• DP/AS-i Link Advanced double master 6GK1415-2BA20
• IE/AS-i Link PN IO single master 6GK1411-2AB10 (engineering software V9 or V8.1 and V8 only)
• IE/AS-i Link PN IO double master 6GK1411-2AB20 (engineering software V9 or V8.1 and V8 only)

The CM AS-i Master ST module is supported with IM 155-6 PN High Feature within an ET 200SP station interfaced via PROFINET.

The AS-i Master CP 343-2 and CP 343-2P are supported within an ET 200M station interfaced via PROFINET or PROFIBUS.

With the CM AS-i Master ST, CP 343-2 or CP 343-2P modules, digital AS-i slaves with standard addressing and extended addressing (A/B slaves; see also remark under the Area of Application heading) can be operated via the library.

In combination with the IE/AS-i Link PN IO and the DP/AS-i Link Advanced, it is possible to integrate digital and analog AS-i slaves with standard and extended addressing (A/B slaves).

Hardware and software requirements

The libraries require the following PCS 7 versions:

• Engineering software V9: PCS 7 version from V9
• Engineering software V8.1: PCS 7 version V8.0 SP1 Update 3 and higher, can also be used for PCS 7 versions V8.1 and V8.2
• Engineering software migration V7-V9: PCS 7 version V8.0 SP1 and higher, can also be used for PCS 7 Version V8.1, V8.2 and V9
• Engineering software V7: PCS 7 version V6.1, V7.0 or V7.1

The engineering software migration V7-V9 comprises the same interconnection logic of the CFC blocks as the engineering software V7 and is recommended for the switch to PCS 7 V8 or PCS 7 V9 with only a few adjustments required in the PCS 7 project.

The engineering software V9 and engineering software V8.1 use APL interconnection logic and are recommended for new PCS 7 projects.
