An IGSS object must have a unique name and an object name must be unique within the area it is created in.
If you create, insert through copy-paste routines or import an object with a name that already exists, the newest object will be renamed with an "_1" suffix to the name. If you continue to create, insert through copy-paste routines or import the same object, the suffix for each new object will increased by one to "_2".
Example
If you insert an object named TempAnalogObj into an area that already contains an object named TempAnalogObj, the new object you are inserted will be renamed TempAnalogObj _1.
If you insert the same object again, the new object you are inserted will be renamed TempAnalogObj _2 as the TempAnalogObj _2 still exists.
The object name is case-sensitive, differentiating between upper-case and lower-case letters. These two objects are not identical:
The object name can only consist of 30 characters. You cannot enter an object name that consists of 31 or more characters.
The following characters are permitted for use in IGSSobject names:
Upper case text
| A | B | C | D | E | F | G | H | I | J | K | L | M |
| N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
Lower case text
| a | b | c | d | e | f | g | h | i | j | k | l | m |
| n | o | p | q | r | s | t | u | v | w | x | y | z |
Numbers
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
Special Characters
| $ | . | + | : | - | _ | * | / | - | ? | = |

| µ | È | Ò | Ý | ç | ñ | ü | º | É | Ó | Þ | è | ò | ý |
Spaces
An object name may contain spaces.
Be careful when using spaces to name objects. The IGSS system will not remove leading or trailing spaces, which means the following objects are not identical:
The second Analogobject01 contains a leading space and could likewise also contain on or more trailing spaces, making visual identification difficult if not impossible.
You can also end up creating an object solely defined by spaces, thus an object can be named <space> and it is theoretically possible to create an object named <space> in the area named <space><space> and represented in the diagram named <space><space><space>.
