To program a CQM1 PLC using the programming console, it is necessary to convert the ladder diagram into a mnemonic.

Normally open conditions closed CQM1 6.2- Mnemonic code A normally closed condition is ON if the operand bit is OFF to OFF if the operand bit is ON.

A normally open condition is ON if the operand bit is ON to OFF if the operand bit is OFF. A ladder diagram is shown below: LD OMRON CQM1 contact diagram 6.1- Fundamental terminologyД®ach condition in a ladder diagram is ON or OFF depending on the state of the operand bit assigned to it. The logical combinations of these conditions determine when and how the instructions on the right are executed. Along the instruction lines are the conditions leading to further instructions on the right side. The branch lines are called the instruction lines. The line on the left is called the bus bar. 6- The basics of the ladder diagramДЄ ladder diagram consists of a down line on the left side with lines branching out to the right. They are sometimes entered as real numeric values but generally correspond to zone channel addresses or to bits containing data to be used. Operands provide information regarding the execution of an instruction. Most instructions have at least one associated operand.

The instructions used on the right side of the diagram, executed according to the conditions found on the instruction lines.

Instructions that correspond to conditions, used as instructions only when converting to mnemonic.

There are two types of ladder diagram instructions:

After installation of the complete control system and when it is ready for use, run the program and make the necessary adjustments.

Run the program to check for runtime errors and correct them.

Check the program for syntax errors and correct them.

Using the programming console involves converting the program into mnemonic form.

Enter the program in the central unit.

Determine which words are available for the work bits and prepare an allocation table for these according to their use.

List all I / O devices and I / O points and prepare a table showing the I / O bit assigned to each I / O device.

The вЂњSYSWINвЂќ software allows programming of вЂњOMRON-CQM1вЂќ PLCs used in many automated systems.

OMRON CQM1 console 2.2- The SYSWIN software: SYSWIN OMRON CQM1 The basic functions of these programming consoles are identical. Two programming consoles can be used with the CQM1: the CQM1-PRO01-E and the C200H-PRO27-E.
