    Default Send command to RTU

    How can I send command to RTU using IEC-870-104 protocol? Do you have any examples?

    shortly: you must create a command variable (e.g. with T45 for single-command or T46 for double-command) with the COA and IOA as the RTU expects. And then you set value 0 or 1 to the variable (or better - you use zenon module Command Input to process it).

    details: what about zenon Energy training? Energy is a complex topic and the IEC60870 Standard is a sophisticated communication protocol. IMHO it is something one needs more as few questions and answers on a Forum.

    Hi,

    It may depend on the version that you are using. In earlier versions a limit text for the direction was required, and this was obtained through the reaction matrix.

    In later versions you can still use the reaction matrix, but a standard direction text for ON / OFF is used when no reaction matrix is linked.

    Best regards,
    Mark
