TMDS243EVM: EtherNet/IP Adapter, Connection Manager implementation

Vaclav Vadinsky

Part Number: TMDS243EVM

Tool/software:

Hello,

based on the EtherNet/IP Adapter Generic Device Examples, I am trying to implement my own Generic Device.
I have the given EDS file.

The device identification works. I have implemented a custom CIP Class tested with EtherNet/IP Tools from Molex. I have implemented [Assembly].
I don't know how to implement the [Connection Manager] part in the code and its binding to [ASSEMBLY]

I didn't find in the demo the part of the code where the [Connection Manager] is created. But the demo with PLC works, but my project does not.

Can you please advise me how to implement [Connection Manager]? Is it somehow related to functions like EI_API_CIP_createRoutingAssembly?

Hi Vaclav,

the connection manager is already implemented in the stack, see the "standard Objects" in datasheet:

EtherNet/IP Adapter: Datasheet

First, you need to create your assembly instance via EI_API_CIP_createAssembly .

Regarding binding your assembly to your objects, you can use EI_API_CIP_addAssemblyMember to bind your attribute to your assembly, as is also done in the Generic Device example:

Alternatively, if you want to receive callbacks when your attribute is accessed via an IO connection, you can use EI_API_CIP_addAssemblyMemberCustomMapped. See the Discrete I/O example implementation, where this method is used.

Let me know if you have any questions.

Best regards,
Pourya

Hi Pourya,

Thank you for your reply.
I had a bad Assembly ID that didn't match with the EDS file.
I am now moving on with development.

Best regards,

Václav
