Course Objectives

RTU (Remote Terminal Unit) is a microprocessor based device that monitors and controls field devices that then connects to plant control or SCADA (supervisory control and data acquisition) systems. Due to some potential benefits, RTU is much more powerful than a PLC as the RTU can have several inputs and outputs.

A RTU can sometimes be programmed through a simple web interface. In other instances, the RTU comes with setup software that can help you to configure input streams to output streams as well as communications. There are also many RTU’s that have preprogrammed modules that can just be applied for the desired function. This advantage can quickly be turned into a disadvantage.

This 4-day workshop would assist the participants in understanding how to manage the reliable RTUs using Ladder programming as well as other PLC programming languages to make the ever changing technologies do a remarkable job of leveling the playing field.

After successful completion of this workshop, participants will be able to

  • Understand the ACE RTU’s Ladder Programming
  • Familiar with ACE 4600 Gateway Programming
  • Learn what are the MODBUS Interface and devices
  • Learn MODBUS Programming in ACE RTU
  • Understand MODBUS Slave Setup
  • Understand MDLC and MDLC over IP
