What is a moving symbol object?

Definition

A moving symbol is an area within which a standard IGSS symbol may move. The movement and other properties of the symbol are controlled from the PLC system.

Use

A moving symbol object may be used to show the progress of some operation in the plant, for example, how far a particular item has reached on a transportation band.

Key features

When you create a moving symbol object, the special properties controlling the object are automatically inserted in the Value column on the Table tab.

The values have the following functions.

This value …	Defines …
[x]	The symbol’s x-co-ordinate.
[y]	The symbol’s y-co-ordinate.
[c]	Applicable to monochrome symbols only. Type the number of the color you want to use. The number must be between 0 and 15. You assign a color to a number by inserting the relevant color code in hexadecimal or decimal form in the Windows Registry. The registry keys are found in the following branch: HKEY_LOCAL_MACHINE\SOFTWARE\ 7-Technologies\IGSS32\v5.00.00\DefRun32\ MovingSymbols.
[s]	The index of the symbol in the symbol file. To find the index, select Symbols in the Edit menu. Find the relevant symbol, right-click and select Properties. On the Symbol Properties tab beside the Symbol name field, the index is shown as “S = xxx”. The symbol index is calculated by combining the table number (0 – 24) with the symbol number (01 – xx). In table 0, you write 1, 2, 3, … (instead of 001, 002) In table 1, you write 101, 102, …
[a]	The angle of the symbol. The angle may be 0, 90, 180 or 270 degrees.
[m]	Whether the symbol image is mirrored or not. If set to 1, the image is mirrored. If set to 0, it is not mirrored.
[min x]	The leftmost x-co-ordinate of the area within which the symbol will move.
[max x]	The rightmost x-co-ordinate of the area within which the symbol will move.
[min y]	The bottom y-co-ordinate of the area within which the symbol will move.
[max y]	The top y-co-ordinate of the area within which the symbol will move.
