LP-AM243: LP-AM243

We are trying to evaluate LP-AM243 for EtherNet/IP adapter using industrial communication SDK as mentioned in the link below–

https://dev.ti.com/tirex/explore/node?node=A__AD2nw6Uu4txAz2eqZdShBg__INDUSTRIAL-COMMUNICATIONS-SDK-AM243X__P--DGtH__LATEST

We are using following file to change the IP address.

Is this the right way to change the IP address of LP-AM243?

Query # 1 : For communication we need to change the IP ADDRESS of the board LP-AM243. Please share the steps to change the IP Address in LP-AM243.

You can use molex tool to achieve the same: Use the below object in molex tool to change the IP address. You can download molex tool from: 

TCP/IP Object[edit]

This object is used to read/write DUT interface settings and their configurations. The Configuration Control Attribute (Attr. 3) will show whether the DUT uses permanently stored IP or an IP address assigned via DHCP.

Query # 2 : How to check the current IP address of the board LP-AM243?. Please share the ways to check the IP address of the board LP-AM243.

It gets printed on UART terminal and alternatively you can use molex tool to get this attribute

Query # 3 : Please share the configuration / EDS file to load it to PLC to connect the LP-AM243 in the PLC network.

It is packaged as part of SDK you can find in industrial comms sdk:  examples\industrial_comms\ethernetip_adapter_demo\device_profiles\generic_device\eds

Hi Nilabh,

I am not able to download molex tool. Could you share the downloadable molex tool link again. Is there any document which we can refer to change the ip address using molex tool.

Thanks

Hi Surbhi,

Unfortunately I also see that the tool has been removed by the company. They no longer support it. Other option is to use CTT Tool, which is provided by ODVA. You can download CTT Tool from ODVA if you have member login.

Hi Nilabh,

As of now we don't have member login of ODVA. Without login we are not able to use that tool. Is there any alternate approach.

When I am searching other options, got this link - 

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1248948/lp-am243-problems-discovered-when-modifying-ethernet-to-static-ip

As mentioned, by modifying one of the source file of the sdk we can change the ip address.

Similar approach is not there for ethernetip_adapter_demo sdk

https://dev.ti.com/tirex/explore/node?node=A__AD2nw6Uu4txAz2eqZdShBg__INDUSTRIAL-COMMUNICATIONS-SDK-AM243X__P--DGtH__LATEST

can we change any file to change the ip address.

Thanks

Hi Surbhi,

The above e2e is about general ethernet example where the complete code is open source, where as in case of EIP the stack sources are not public, they are distributed as a binary. Let me check if there is any other way around it

Also I would recommend getting an odva login, sinece you are starting the EIP development, as it will facilitate with you more collaterals about EIP

Hi Nilabh,

I have checked with other teams internally, we have ODVA membership.

We got the molex tool also. But we are not able to configure the IP settings in LP-AM243. Could you please help us out in using the tool.

I am not sure if we are missing any steps in configuring the EtherNET port in LP-AM243. Default IP address of the device is 192.168.1.10. And we want to change it to our PLC subnet.

Thanks.
