Storing/Loading the Firmware to the SD Memory Card for AC500 V2 Products

Procedure for AC500 V2 Products

  1. Initialize the SD memory card, i.e., create the file structure the CPU requires by, for example, inserting a new SD memory card into the AC500 PLC SD Memory Card in AC500.

  2. Copy the firmware files into the corresponding directory:

    AC500 CPU Directory File
    PM5xy

    FIRMWARE\<PLC type>\<firmware version number>

    Example: FIRMWARE\PM564\2_4_4

    		 *.GZA

  3. Change the command \ file SDCARD.INI located in the root directory on the SD memory card as follows:

    • In section [Status] set the key FunctionOfCard to “2”, if you only want to update the firmware or “3” for firmware and user program update (i.e. FunctionOfCard=2).
    • In section [FirmwareUpdate] set the key CPUPM5x1 to “1” [=update always] (i.e. CPUPM5x1=1)

A specific firmware version can be loaded. This is done by setting the key CPUPM5x1 to “2” [= update, if versions are different] or “3” [= update, if version on SD memory card is newer] and creating an according key for the CPU in the product specific section of SDCARD.INI. The firmware has to be copied to the according directory SD Memory Card in AC500.
