Add MELSEC

The system configuration when using Mitsubishi Electric FA allows for configuring a MELSEC within ICONICS Workbench. See MELSEC System Configuration for more info.

Note: MELSEC can only be edited when disabled. When the device is activated, settings cannot be changed until the device is disabled. See Activate and Disable.

To Add MELSEC

In the Workbench, expand your project in the Project Explorer, and then expand the Data Connectivity node. Right-click the Mitsubishi Electric FA node and click on Add MELSEC as shown below.

· Data Type *3 - Use the pulldown menu to select the tag's data type.

Options include:
BOOL *1, WORD, DWORD, INT, UINT, DINT, UDINT, LINT, ULINT, REAL, LREAL, STRING, WSTRING, STRUCTURE (*2)

*1 The BOOL can be used by specifying the bit position (e.g., EG0.1)
*2 The name of a device structure is displayed in the parentheses.

*3 All available the data types support the array type.

· Array Settings - Click the "Edit setting" icon to display the Array Configuration window. If the tag is an array type, the cell displays the shape of it (e.g., (0..2) for a single-dimensional array with 3 elements). If the tag is not an array type, the cell displays “Disabled”.

Please refer to Array Configuration Details for details.

· String Length - If the tag is a STRING or WSTRING type, the sell displays the length of the string (default: 32). The length of the string can be changed between 1 and 255. If the

tag is not a string type, the cell is blank.

· Move element up - Move the selected element one up. This cannot be used if the element is already on the top of the list.

· Move element down - Move the selected element one down. This cannot be used if the element is already at the bottom of the list.
