ioPAC8500_iec_di scenario

## Operating Environment

### Hardware Environment

- CPU module:

    ioPAC 8500-9-RJ45-IEC-T

- Slot 1:

    85M-1602-T

- Slot 2:

    85M-2600-T

### Software Environment

- Programming Tool:

    ISaGRAF 6.3

- Configuration Tool:

    Moxa RTUxpress 1.1

### Config Setting

Config file: ioPAC8500_iec_di.rtu

## Step by Step

### Initialization

1. Import config file onto ioPAC
2. Open IEC project via ISaGRAF
3. Build -> Build Solution
4. Import IEC porject onto ioPAC

### Step 1

Prog1 check the DI0 and DI1 status and doing the OR operation, the boolean result will set to DO0.

### Step 2

Prog2 detect DI2 status and then set to DO1 channel to start or stop PWM.

### Step 3

Prog3 detect DI3 counter value, if its value > 10, then set DO2 ouput PWM 5 times.
