Check these threads linked here if that helps untill you get help from some expert of this topic. http://www402.abbext.com/AnswerQuestions.aspx?keywords=ci867,
Linked app is for modbus rtu just as an example...
Channel parameter is the mounting position of CI867 itself and Partner should be based on slave position. if it is connected to Ethernet1 it will be 1.X , where X is the slave id in the structure and not the IP address !
