CRCI Cеть промышленных контроллеров

The Industrial Controllers Networking, "CRCI", unit is based on a modular design structure whose functionality is divided into different modules to allow the student a better understanding of the unit. The modules provided with the unit are: two Industrial Controllers, Set Point Generator, Interface Card (to be placed in a computer slot) and Control Configuration Software.

• 2 Industrial Controllers modules, each one is composed of: an industrial controller with 2 analog inputs and an analog/digital output. The analog inputs are used to connect the process variable value (PV) and set point value (SP) signals respectively. The analog/digital output is used for delivering the output process value (OP). The controller also has two relays. The industrial controller is connected via field bus (Profibus DP) through an interface card with a computer (PC).
• Set Point Generator module: it allows to generate a step signal by switching between two different selectable voltages. The voltage levels can be adjusted using two potentiometers.
• Interface Card (to be placed in a computer slot): it allows the controllers signals to be available for a computer PC, for further processing.
• Software, composed of:

• The OPC server configuration drivers: allows the modules data to be available for others programs.
• The Control Configuration Software: allows to set the industrial controllers parameters. Several functions such as recorders and alarm logs enable a simple control room function to be simulated.
