sir ,I have to connect emerson plx32 pro soft to 800 xa through mbtcp.but here no ci867
If your hardware configuration does not have any CI867 ModbusTCP card, you can use PLCConnect Aspect to connect Emerson Plx32 System to 800xA.
If you present license does not have PLCConnect option, you have to upgrade your license as well.
Also as an alternative way, just for monitoring(not for control), you can use Generic OPC Network + Kepware (or similar thir party software)
Hope it helps you.
