Automation of a Pneumatic Cement Transport Installation Using PLC

The paper proposes the use of the PLC for the automation of a pneumatic cement transport installation. This type of installation is used inside cement plants as part of the cement production process and other products derived from it. PLCs control installation replaces a classical control installation, less reliable, with contacts and relays. For the control of the pneumatic transport of the cement was using Zelio PLC and one extension module, to increase the numbers of digital inputs and outputs, connected to PLC. The program was developed in function block diagram. Using PLC's controls, the installation has been considerably simplified, and troubleshoot installations are much easier.
