SOEM master slave communication

[nehapagare17]

I have configured one linux based computer as master and other linux based computer as slave ,now i want to establish connection between both of them but i tried executing slaveinfo.c file build it in code block .but i am not getting executable file .what should be the next step and procedure to execute these file

You forget to tell exactly what steps you have taken. SOEM is only an EtherCAT master library. It can not be configured as a slave. The standard way for a slave is to have a piece of dedicated hardware called the ESC (EtherCAT slave controller). It is possible to emulate the ESC in software, but I do not know of any open-source projects that implement that.

My suggestion is to read more about what EtherCAT is and how it works.

I have configured one PC as master using SOEM and other PC as slave using SOES. Now I have tried various steps to establish communication between them I have connected cables .but not getting where I am going wrong can you explain in brief how to make them communicating

SOES will not implement a full EtherCAT slave. SOES is used to communicate with the ESC (see post above) for the higher level protocols. Without the proper hardware (or emulator) you can not have a working EtherCAT system. If you want to use a PC as slave you can use a device like this : https://www.beckhoff.com/en-en/products/ipc/pcs/accessories/fc1121.html As a side note, there is currently no driver in SOES for the fc1121.
