Low-cost Industrial controller based on the Raspberry Pi platform
| Resumo: | The low-cost automation field exhibits the need of innovation both in terms of hardware and software. There is a lack of devices that allow the development of control logic that is free from restrictions of domain-specific communication platforms and at the same time able to provide the capabilities aligned to the Industry 4.0 requirements. The objective of this work is to develop an inexpensive, small Industrial Controller that supports the execution of programs in different industrial programming languages. So, it is intended to develop, manufacture and control a low-cost but powerful Industrial Controller based on the use of the single-board computer Raspberry Pi. The study described in this document was carried out on the creation of a hardware platform that is capable of integrating with software frameworks compatible with standards updated and widely used in the industrial automation field. IEC 61131-3 is employed displaying the ease of use and implementation alongside multiple well established programming languages for automation through the OpenPLC platform while IEC 61449 is employed through the 4DIAC framework that has a clear and objective environment capable of providing the appropriate tools for implementation of a distributed control. It is employed the single-board computer Raspberry Pi, a robust device with adequate processing power and communication capability for the elaboration of a platform in the low-cost automation scope. The elaboration of the Industrial Shields, responsible for providing the controller I/O interface took into consideration maintenance concerns of controller integrity through the application of galvanic isolation in the automaton input and output sections. The proposed platform was successfully tested in an automation system prototype comprising Fischertechnik’s Punching Machine being possible to develop the control logic using IEC 61131-3 and IEC 61499. |
