Elipse power with iec60870-5-104 slave driver

Dear Sir/Madam.
I’m a newbie about the Elipse Power studio Software.
In my starting Project, I used 2 drivers, they were IEC 69870 5 104 Master for communicating to field device and IEC 69870 5 104 Slave for connecting to control Center. I mean that I need to used Gateway Function. At the Elipse power studio software, I can monitor and send command to filed device OK.
From control center, I also monitor the field devices via Elipse software. But I couldn’t send command successfully?
Anyone have ideal. Please help me.
Thank much.
