Chapter 14 Operation Examples

To understand the basic operation of the MICRO-EH, this chapter explains samples of operations such as inputting simple programs and verifying operations.

The following programming devices can be used:

	Peripheral unit name	Form
1	H series ladder diagram	HL-PC3
	instruction language software	HL-AT3E
	LADDER EDITOR
2	H series ladder diagram	HLW-PC3
	instruction language software	HLW-PC3E
	LADDER EDITOR for Windows® version

* Graphic input device (format: GPCL01H) can be used except on-direct mode.

(1)Operation verification procedures

An operation is verified according to the following procedures:

Start


Start the LADDER EDITOR for Windows®		STEP	1

Perform initial settings		STEP	2


Input program		STEP	3


Check program errors		STEP	4

Save program		STEP	5

Transfer program to the CPU		STEP	6

Monitor (verify the operation)		STEP	7


End

A personal computer and LADDER EDITOR for Windows® are used as the peripheral units in the example. For details, refer to the user's manual for each peripheral unit.

(2)Detailed operation example

The following explains an operation example using the module and sample program from step 1.

CPU: 14-point type

Slot 0: Bit point X48

Slot 1: Bit point Y32

Slot 2: 16 vacant points

Input/output operating mode: Mode 0 (WRF070 = 0, default value)

Operation of program

Turn Y100 and Y 102 on and Y101 and Y103 off and vice versa, alternating at one second intervals.
