Good Morning @Thanh_Minh .

It seems you are configuring commands.

Under Easergy Builder point of view, commands come from "slaves" devices like a scada system (Source) to be executed on "master" devices like a protection (Destination).

What I mean is that, no matter the model of RTU you are configuring (PowerLogic T300, Saitel DP/DR or PowerLogic T500), from the perspective of the communication protocol used to interact with a scada system, the RTU works as a slave device. On the opposite, when it sends a command to an IED (Protection Relay or else), it works as a master.

That is the reason for which you must put an IEC104 master device under the column destination to make it work.

Does the command from the Zenon SCADA update the variable in CoreDB ?

• If yes, is it the right value?
• If no, have you checked the traces to see what error code is returned to the SCADA?

With these protocols, it is important to check that the settings in the T300 match the settings in the SCADA.

• Is the command in the Zenon SCADA also set up to send select-before-operate for CSC?
• Is the Operate command sent within 20 seconds of the Select command?
• Is the T300 time the same as that of the SCADA? They should both use either UTC (Coordinate Universal Time) or local time.
