The new embedded Anybus-S PROFINET interface is a complete PROFINET solution for a PROFINET IO device with IRT functions according conformance class C. The module is based on the Siemens PROFINET IO software technology for IRT and uses the ERTEC 200 ASIC, providing integrated switch functionality. All analog and digital components that are needed for a complete PROFINET IO interface with isochronous real time (IRT) are mounted on the module. The module provides two SC-RJ Fibre Optic connectors and allows installations in line or ring topology. The interface to the electronics of the automation device is based on a 2k Dualport RAM. This interface is standardized in hardware and software and identical in functionality with all other Anybus-S modules.
