Dear Expert

I'm using SMART RTU with diagram below.

The connection Downlink and Uplink was OK.

But when I configure double command signal, I didn't see " Select before execute" field of SendList table. So I couldn't use doube command with Select before Execute.

How can I fix it?

Many Thank.

    Hello John_Capture,

    the parameter you are looking for can be found in the "Project work / I/O-Parameter setting / Double command output" area

    The selection can be made here for each double command.


    Best regards

    Dear Sir

    Thank for your feedback.

    I think that this window was only for binary output module, in my diagram is protocol converter. It mean that this tab can't apply for my diagram.

    Is this true or no?

    on other hand, I tried with Double command DO to SBO function. But it didn't work.

    Hello,

    you are right the current feedback configurate via the I/O parameter path is for binary outputs or for conversion into a corresponding message/double-point information.

    After re-analyzing your request and since it is a direct pass-through UL 104 - DL 104 (without handling in the application), the selection mechanism "Selection before execute" should be passed through 1:1 and no further activation is therefore necessary.

    Dear Sir

    Thank for your feedback.

    1. I don't know if I understand you correctly? with this connection Diagram, Select before Execute isn't configure on SMart RTU. When control center send select before execute command to smart RTU, smart RTU will transfer intact command into downlink device?
    2. In actually, SMart RTU can only received direct command from control center, select before execute command didn't work. How can I dianostic and fix it?
    3. If can, I really hope that you can remote and check the situation.

    Best and Regard.

    Dear Thomas.

    I guess that the problem happen at IEC60870-5-104 Downlink in Smart RTU.

    because I tried test with other case as below picture and it can't still work

    May SBO in IEC60870-5-104 in Downlink connection have problem.
