Investigation of Remote Terminal Unit (RTU) in control systems : Case of incompatibility)

Abstract

In controlling complex and large systems remotely always, there will be two units namely: Master control units and remote control units. The first one known as master terminal units (MTU) which may be located away from the system under control, while the second unit known as remote terminal units (RTU) connected through I/O channel to the field device using the convenient voltage and current to control the device. The RTU work under the command coming from MTU using same protocols For controlling the system between the MTU and device, compatibility is a must. The problem under investigation is to analyze and evaluate how the MTU and device be made compatible through another media, which is RTU560. This device is a converter which combines the two protocols used for successful control.
