General Information
This chapter covers PROFINET specific details in the Anybus implementation. Note that the use of such functionality may require in-depth knowledge in PROFINET networking internals and/or information from the official PROFINET specification. In such cases, the people responsible for the implementation of this product are expected either to obtain these specifications to gain sufficient knowledge or limit their implementation in such a way that this is not necessary. The GSD file must be changed to reflect all changes.
Implementation overview:
- Conformance Class
The Anybus module complies to conformance class C.
- Performance Characteristics
100 Mbps, full duplex with autonegotiation enabled as default
Real Time (RT) communication, 250 μs cycle time
Isochronous Real Time (IRT) communication, 250 μs cycle time
- Device Model
One IO Device instance
The IO Device instance includes an Application Process referenced by its identifier (API). API 0 (zero) is implemented by default.
The API implements one or more slots
Each Slot implements one or more subslots
Each subslot may implement one or more Channels
- Slots & Subslots
Up to 128 subslots in total.
- IO Data
1440 bytes of IO data in each direction, including status bytes (4 bytes for DAP submodules + 1 byte per additional submodule)
