MCU-PLUS-SDK-AM243X: EtherNet/IP Adapter Configuration: Input Only Instance number

Part Number: MCU-PLUS-SDK-AM243X

I built the demo below and checked its operation.

"ethernetip_adapter_generic_device_mii_demo_am243x-lp_r5fss0-0_freertos_ti-arm-clang"

We checked with version 09.00.00.03 of INDUSTRIAL-COMMUNICATIONS-SDK-AM243X.

The Input Only instance number used in the demo has been changed from 254 (0xfe) to 197 (0xc5).

app_generic_device.c

Code before modification

errCode = EI_API_CIP_createAssembly(pCipNode, 0xfe, EI_API_CIP_eAR_GET); // Input-only.

Code after modification

errCode = EI_API_CIP_createAssembly(pCipNode, 0xc5, EI_API_CIP_eAR_GET); // Input-only.

In this case, an error will now occur in the CT19.1 protocol test.

3240 1> *** Expected Successful ForwardOpen: Received General Status 01, Extended Status 0x0100

3241 2> *** Unexpected failure to reuse the existing multicast T->O connection.

Normally, a successful response should be returned to the same multicast connection that has already been connected,

but Extended Status 0x0100 (Extended Status: Connection in use or duplicate Forward Open) indicating a double connection error is output.

Is it not possible to change the Input Only instance number?

Hi Ryohei,

I talked with the experts and they explained to me that it is possible to change the Input Only instance number, but if that is done the configuration of CTT should also be adjusted. So now the question is, was the configuration of CTT also adjusted?

Hi Nilabh,

I changed the Input Only instance number in the SOC file.

Therefore, we have confirmed that communication can be performed correctly except for the error location.

Thanks Ryohei for the info.

So this issue is resolved right?

Hi Nilabh,

Even if the SOC file is set correctly, the following error is output.

3240 1> *** Expected Successful ForwardOpen: Received General Status 01, Extended Status 0x0100

3241 2> *** Unexpected failure to reuse the existing multicast T->O connection.

Hi Nilabh,

I conducted Connection Manager Object Test again on ind_comms_sdk_am243x_09_01_00_03.

The result was the following error:

3405 1> *** Expected Successful ForwardOpen: Received General Status 01, Extended Status 0x0100
3406 2> *** Unexpected failure to reuse the existing multicast T->O connection.

4434 3> *** Expected Successful ForwardOpen: Received General Status 01, Extended Status 0x0100
4435 4> *** Unable to open an Point-to-Point I/O to the same application path.

1 and 2 result in the same error as last time.

3 and 4 have similar error contents, and it seems that the judgment has been added to CT20.

I have attached the results and customized source code.

Hi Ryohei,

we have a fix for this issue but are testing the solution. Nevertheless, we are targeting an intermediate drop before March with this issue resolved.
