    SDO

    in Power PMAC

    Posted

    You can access "ecatsdo" function.

     

    ecatsdo

    Function: Access an EtherCAT Service Dictionary Object (SDO)

     

    Syntax: ecatsdo ({expression},{expression},{expression},

    {expression},{expression},{expression})

     

    The ecatsdo function permits the user to access (write to or read from) the specified EtherCAT Service Dictionary Object (SDO) from within a program.

     

    This function can only be used if Sys.EcatType is set to 0 (Etherlab stack). If Sys.EcatType is 1 (Acontis stack), use the similar ecattypedsdo function.

     

    This function takes 6 arguments.

     

    The first argument is the “direction” of the access. It should be 0 to write to the SDO, or 1 to read from the SDO.

    The second argument is the slave index value “j” of the device, corresponding to the structure ECAT.Slave[j] assigned to the device.

    The third argument is the index number of the SDO.

    The fourth argument is the subindex number of the SDO.

    The fifth argument is the data value for the SDO. If the function is used to write to the SDO (first argument = 0), this is the value that will be written, If the function is used to read from the SDO (first argument = 1), this value is not used (but a value must be present here, even if it is unused, in order for the function to execute).

    The sixth argument is the master index value “i” (i.e. the EtherCAT network index) of the device, corresponding to the structure ECAT.Slave[j] assigned to the device.

    The return value of the function in the case of a valid “read” access is the data value of the specified SDO. The return value in the case of an invalid “read” access is “not-a-number” (nan).

     

    The return value of the function in the case of a valid “write” access is 0. The return value in the case of an invalid “write” access is “not-a number” (nan). Even if the returned value is not really used in the application, it still must be stored somewhere; for example, by assigning it to a “dummy” variable as shown in the example code below.

     

    Example

     

    global sdoresult;

     

    sdoresult = ecatsdo(0,0,$6060,0,10,0); // Write to CAN object

     

    sdoresult = ecatsdo(1,0,$6061,0,0,0); // Read from CAN object

    Hi CharlesP.

     

    Now web access is no problem.

    I updated "powerpmacweb.deb" in 1.4.0.27 release firmware.

    Is there any compatibility issues with the latest firmware(1.6.0.9)?

     

    for example "Diagnostics => Step Move " values seems to have a problem.

    Hi CharlesP~

     

    I'm sorry to be late in replying.

     

    There is no problem (I'm just being test- PC to PPMAC direct connect)

    About Two month before the issue was not.

    But now most PC have same problem.
