ROBO $352$ PLC $/$ Pneumatic Systems $1$

Lab $7$: Omron CJ PLC advanced programming

Objective: To learn advanced programming techniques with Omron CJ$1$M and CJ$2$M PLCs including usage of the program flow and math instructions.

Upon successful completion of this lab, the learner will be able to:

Create a ladder program that consists of separate subroutines

Understand number formats and their connection with different memory areas

Use Math instructions to perform basic calculations.

Procedure:

Part $1-($minimum$)$

Start the CX$-$Programmer and open the PLC file from Lab $6.$

Create two new sections $($in addition to the existing Section$1)$ and name them: Output and Calculation. $($Right$-$click on NewProgram$1,$ Insert Section$)$

Create subroutine instructions that will call Output and Calculation sections from NewProgram$1.$ Make Calculation section active only if SW$2$ is on$.$

Move all rungs that energize solenoids and lights into the subroutine 'Outputs'. Subroutine 'Outputs' is always active.

Download and test the program.

Demonstrate the result to the instructor.
