Siemens S7 using SICOS protocol and S7 functions ID:53


Interface Description

The IGSS32 SICOS S7 communication interface offers connection to Simatic S7 series PLCs using S7 functions as transport for the SICOS protocol.

S7 functions are supported on several different network types including ProfiBus and Industrial ethernet. S7 functions are also supported by a large number of different communication processors for both PCs and PLCs. This gives a great flexibilty in designing the networks for different kinds of applications.

This communication interface can be used for redundant communication by use of S7-REDCONNECT.

SICOS is a state-of-the-art object oriented library of function blocks designed for use with Simatic S5 and Simatic S7 PLC series. The object oriented features of SICOS is extended to incorporate data exchange between PLCs and HMI systems such as IGSS32. This is implemented by using an application layer communication protocol specially designed for fast event-oriented data exhange. The SICOS system gives the programmer full control of then and why data are to be send to the supervision system - thus fully exploiting the bandwidth of the communication link. The SICOS communication protocol and the object oriented features of SICOS is fully integrated into IGSS32.

SICOS systems are used in a large number of industrial applications including oil and gas production, ship automation and other applications which requires minimal response times combined with large amounts of I/O points.
