hi, I want know the detail about using protocol 104 to write float and 32bits string。

hi, I using thoese programs to writing data to 104 server,
InformationObject sc = (InformationObject)SingleCommand_create(NULL, 10, false, false, 0);
printf("Send control command C_SC_NA_1\n");
CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
InformationObject_destroy(sc);

    sc = (InformationObject)SingleCommand_create(NULL, 10, true, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)DoubleCommand_create(NULL, 30, 0, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)DoubleCommand_create(NULL, 30, 1, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)DoubleCommand_create(NULL, 30, 2, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)DoubleCommand_create(NULL, 30, 3, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)StepCommand_create(NULL, 50, 2, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)StepCommand_create(NULL, 50, 3, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)SetpointCommandNormalized_create(NULL, 70, -1, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)SetpointCommandNormalized_create(NULL, 70, 0.1234, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)SetpointCommandNormalized_create(NULL, 70, 1, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)SetpointCommandScaled_create(NULL, 90, -32.768, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)SetpointCommandScaled_create(NULL, 90, 0, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)SetpointCommandScaled_create(NULL, 90, 32.767, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)SetpointCommandShort_create(NULL, 110, 1.2347, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)SetpointCommandShort_create(NULL, 110, 2.4567, false, 0);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

    sc = (InformationObject)Bitstring32Command_create(NULL, 120, 123456);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);

but ,in last two page program, sc = (InformationObject)SetpointCommandShort_create(NULL, 110, 2.4567, false, 0);
printf("Send control command C_SC_NA_1\n");
CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
InformationObject_destroy(sc);

    sc = (InformationObject)Bitstring32Command_create(NULL, 120, 123456);
    printf("Send control command C_SC_NA_1\n");
    CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
    InformationObject_destroy(sc);`

I can‘t using the program to write data , the messages to server are listed below。
I find those message are not 32bits string message or float message but scaled num message, so it write fail, I want to know the reason about it please.

OH, there is not any help for me?

You must first send the selection command, and then send the execution command.

/**

• \brief Create a single point command information object
• \param[in] self existing instance to reuse or NULL to create a new instance
• \param[in] ioa information object address
• \param[in] command the command value
• \param[in] selectCommand (S/E bit) if true send "select", otherwise "execute"
• \param[in] qu qualifier of command QU parameter(0 = no additional definition, 1 = short pulse, 2 = long pulse, 3 = persistent output)
• \return the initialized instance
  */
  SingleCommand
  SingleCommand_create(SingleCommand self, int ioa, bool command, bool selectCommand, int qu);

like thise

sc = (InformationObject)SingleCommand_create(NULL, 10, true, true, 0);
printf("Send control select command C_SC_NA_1\n");
CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
InformationObject_destroy(sc);

sc = (InformationObject)SingleCommand_create(NULL, 10, true, false, 0);
printf("Send control execute command C_SC_NA_1\n");
CS104_Connection_sendProcessCommandEx(con, CS101_COT_ACTIVATION, 1, sc);
InformationObject_destroy(sc);
