OMRON Programming Basics : CX PROGRAMMER
Friends today we are here with programming basics for OMRON. Here we are guiding you towards CX- programmer software use. The PLC specifications and programming basics will be different for different software. For Siemens you have to visit our programming basics article in Simatic manager.

A ladder rung is a horizontal slice of a ladder program which contains a complete, single set of logic instructions which power to flow from left power bar to the right.
CX-Programmer automatically creates space for a new rung at the bottom of the program section. To enter element in rung further up the program, it is necessary to manually insert a new rung into the ladder editor. When the new rung space has been placed, elements(contacts/coils and instructions) may be entered.
The Section/Rung manager can be used for easy manipulation and commenting of rungs.
[Simple dialog mode]
The following can be input as the first operand (The TIM/CNT number) of TIM/CNT instructions.
- TIM/CNT number
- 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.
Comment display of the first operand of TIM/CNT instruction in Ladder View
- If the TIM/CNT number is input as the first operand, the comment of a TIM/CNT contact is displayed.
- If a NUMBER-type symbol name is input as the first operand, the comment of the symbol is displayed
