### Introduction

This is relay IEC sample project. The ioPAC8600 controller use relay to control ioPAC5542 power on / off.

ioPAC8600_iec_relay scenario

## Operating Environment

### Hardware Environment

- CPU module:

    ioPAC8600-CPU10-RJ45-IEC-T

- Backplane module:

    ioPAC8600-BM009-T

### Software Environment

- Programming Tool:

    ISaGRAF 6.3

- Configuration Tool:

    Moxa RTUxpress 1.3.2 Build 15040714

### Config Setting

Config file: ioPAC8600_iec_relay.rtu

## Step by Step

### Initialization

1. Open .rtu config file and setup your own setting (e.g. IP)
2. Import config file onto ioPAC via RTUxpress
3. Open IEC project via ISaGRAF
4. Build -> Build Solution on ISaGRAF
5. Import IEC porject onto ioPAC via ISaGRAF

### Step 1

Any device which is not over-spec can connect to relay module for power on/off purpose (ioPAC5542 is an example for this scenario only). Connect external power supply + through Relay Channel 0 RO_No and RO_C to device power + . Connect device power - to external power supply - .

### Step 2

Check all IO wiring and power on ioPAC8600 and check device which is been control is still power off.

### Step 3

Start to download ISaGRAF project and after executing relay on, the device will power on.
