Developing the First Program

This section lists the minimum hardware and software requirements, and gives an overview of program

development procedures.

Hardware and Software Requirements

The following hardware items are required to complete the first program.

 1 x ioPAC RTU controller

 1 x 9-48VDC power supply

 1 x Ethernet cable

 1 x PC or Laptop with following minimum requirements

Development Procedure

Follow the steps below to complete the first program development.

Step 1: Connect an RTU to a Linux PC

Step 2: Install the Toolchain onto the PC

Step 3: Set Cross Compiler & glibc Environment Variables

Step 4: Develop Code & Compile the Program

Step 5: Upload & Run the Program

Configuring the Ethernet Interface

The network settings of the ioPAC RTU controller can be modified with the serial console, or online over the

network.

Modifying Network Settings with the Serial Console

In this section, we use the serial console to configure network settings of the ioPAC.

First, use the command

#cd /etc/network

to change to the directory where the network’s configuration files are located.

root@Moxa:# cd /etc/network/

root@Moxa:/etc/network/#

Call up the vi text editor to begin editing the interfaces configuration file by typing:

#vi interfaces

You can configure the ioPAC RTU controller’s Ethernet ports for static or dynamic (DHCP) IP addresses.
