[Simple dialog mode]

The following can be input as the first operand (The TIM/CNT number) of TIM/CNT instructions.

1. TIM/CNT number

2. The name of NUMBER-type symbols registered in symbol tables

The case of 1.

If a comment is entered in the [Edit Comment] dialog of the first operand, a TIM/CNT contact (BOOL type) of the TIM/CNT number is registered in Global symbols table without its name and with its comment. If the corresponding TIM/CNT contact exists in the Local or Global symbols tables, a TIM/CNT contact is not newly registered.

The case of 2.

The registered comment becomes edit-active in the [Edit Comment] dialog, and the changes are reflected in symbols table. A TIM/CNT contact is not newly registered.

[Detailed dialog mode]

When a name of a new NUMBER-type symbol is entered in the [Find Symbol] dialog displayed by pressing the [...] button in the operand box of the instruction dialog, the entered NUMBER-type symbol is newly registered in the Local symbols table. At the same time, the corresponding TIM/CNT contact (BOOL type) is registered in Global symbols table without its name and with its comment. If the corresponding TIM/CNT contact exists in the Local or Global symbols tables, a TIM/CNT contact is not newly registered. If the type of symbols entered as the first operand is not NUMBER, the corresponding TIM/CNT contact is not registered in symbols tables.
