Technical Data - V3
Description
The EtherNet/IP Adapter firmware implements all CIP objects and services to build an EtherNet/IP Adapter device that can pass ODVA's conformance test.
This in addition requires a correctly behaving host application that interfaces to the firmware through the Dual Port Memory (DPM) interface.
Configuration
The stack can be configured via data base files (generated with Hilscher's Sycon.net or Communication Studio) or via the DPM's mailbox interface (refer to the corresponding API manual).
During connection establishment to an EtherNet/IP Scanner (PLC), it is possible to pass configuration data to the host application.
Implicit Messaging (Cyclic Data)
Through the DPM the host application has access to the process data that is consumed and produces by the firmware.
Explicit Messaging (Acyclic Data)
Acyclic services received from the network and addressing 'build in' CIP objects (CIP objects that are part of the firmware's default CIP object model) are handled by the firmware itself.
There is the possibility to extend the default object model by additional CIP objects, e.g. to support CIP profiles or vendor specific CIP objects.
Key Features

- CIP Sync 1)
- QuickConnect (Fast Startup)
- NULL-ForwardOpen
- CIP Safety "Ready" (provides all necessary features and interfaces to attach a CIP Safety stack on top)
- Firmware built-in CIP Object model can be extended by additional CIP objects (e.g. to support CIP profiles)
