Proposta para acesso remoto a equipamentos de automação industrial utilizando a internet

Abstract

Industrial automation is increasingly present in companies with the constant emergence of new technologies. A constant task for automation professionals is the technical assistance, which should be made directly on the client, for machines and for processes, a task that in most cases, consumes greater travel time to the client that the time required for the realization of the activity, wasting valuable time that could be used for other activities. Thus, this research presents a proposal to use a device that allows the realization of technical assistance in automation systems without the need to travel to the customer, in other words, remotely over the internet. To achieve this objective it was chosen the router EWON Cosy, from EWON company. For carrying out the necessary tests and subsequent evaluation of the results, the automation of a real machine architecture was used, adapting the same to use the router for remote access, performing the tests as if they were made in the laboratory. With the tests, it was possible to prove the possibility and feasibility of use of the equipment for remote access on several equipment of an industrial automation system. Comparative of times required for software changes in some automation equipment of the proposed architecture were made, between the directly and remotely form, with a significant increase in the time required for carrying out remotely change. Despite the increased time required to perform the changes remotely, it was considered feasible to use the remote access because the travel time for performing similar assistance would be even greater, as well as the involved costs. The study was conducted for remote access to connected devices via Ethernet / IP network, with the further possibility to use the same equipment with other forms of communication.
