PROFINET IO describes a device model oriented to the PROFIBUS framework. It consists of places of insertion (slots) and groups of I/O channels (subslots). The PROFINET IO engineering is performed in a way familiar to PROFIBUS. The distributed field devices are assigned to the controllers during configuration.

FOUNDATION Fieldbus High Speed Ethernet (FF HSE) FOUNDATION Fieldbus (FF) is a fieldbus protocol based on international standards and designed for applications in the manufacturing industry, process automation and buildings automation. The guidelines for this fieldbus standard are published by the Fieldbus Foundation. FF defines two communication profiles, H1 and HSE. The H1 profile allows a transmission rate of 31.25 kbit/s. It is preferably used for direct communication between field devices in one link (H1 link). The HSE profile is based on standard ethernet serves first and foremost as a powerful backbone for the link between H1 segments. Typically transmission rates are: 10 Mbit/s or 100 Mbit/s. The first devices that are already available on the market and support the HSE profile are FF linking devices (for example LD 800HSE). They serve as a gateway between the field devices on the H1 segments and the HSE backbone. The FOUNDATION Fieldbus is linked to the AC 800M via the high-performance HSE bus using FF linking devices. More detailed information on the HSE profile can be found in the FF specifications. 

The fundamental concepts behind HSE are explained in the FF specifications System Architecture (FF-581) and HSE Profiles (FF-941). The FF subsystem consists of FF linking devices (for example LD 800HSE, see Appendix C, Recommended Components) which communicate with one another using the HSE protocol. An FF linking device usually provides more than one FOUNDATION Fieldbus H1 segments (H1 link). FF linking devices with a device class of 42c allow process data that have been published cyclically on the subsidiary H1 segments to be “republished” on the HSE segment. By using HSE republishing, it is possible to configure cyclical communication between field devices on different H1 segments and devices on the HSE segment.The FOUNDATION Fieldbus HSE and H1network and the devices are configured with the Fieldbus Builder FOUNDATION Fieldbus. The FF subsystem is interfaced to the IEC 61131 controller (AC 800M) using a FF HSE unit CI860 in the AC 800M, see Figure 7 on page 39. From the perspective of FF the FF HSE unit is an HSE device which participates in the HSE communication.
