61850 with direct normal security command.

Hi guys
I am using a scada software for supervising and controlling into ret615 relay according to 61850 protocol.
With report control block, they were ok on software.
The breaker was direct with normal security , on scada software I wriite value 1 to pos.oper.ctrlval ( open command), this was ok. Buy when i sent value. ( open comand), nothing happen. I switch device into local mod end executed close command from closing button on front HMI.
I search on some forum and they said i need write value 1 into opcls variable ( for close command). But opcls is st variable , couldnt control.
Anh ideal for me.
Thank
