Add MELSEC

The system configuration when using Mitsubishi Electric FA allows for configuring a MELSEC device within the Workbench. See MELSEC System Configuration for more info. The displayed items vary depending on the selected device and communication path.

MELSEC devices can only be edited when disabled. When the device is activated, settings cannot be changed until the device is disabled. See How to Activate a Mitsubishi Device.

      This option is grayed out when the "Use Simulator" checkbox is OFF or when the CPU series is LHCPU or FX5CPU.

    Other Settings

    • Merge Gap - Enter the value that indicates the number of non-contiuguous registers that can be read n a batch in a single communication between Mitsubishi Electric FA and MELSEC devices. This value should be larger than the number of registers between the tags being monitored. If the value is too small, multiple communications will be required to read the data. This setting is for adjustment purposes and is usually recommended to leave it at its default value of 64. Please refer to Merge Gap Details for details.

    • Encoding - Use the drop-down menu to select an encoding from Not Specified, Unicode (UTF-16), Shift_JIS, GB18030, Big5, or KS X 1001.
