Improved control and monitor two different PLC using LabVIEW and NI-OPC server

Abstract

<span>This paper proposes an improved control and monitors between two different PLCs, the Mitsubishi, and Omron. The main advantage is interoperability and communication between both PLC. The use of NI OPC server as the software interface reached interoperability and communication. There were developed two field applications to test interoperability. Laboratory virtual instrument engineering workbench (LabVIEW) uses as the software application for creating the user interface to control and monitor. This improvement show OPC server technology solves data compatibility issue between different driver controller’s and reducing development cost. Regardless of whether there are more than two different PLCs, it's enough to use the NI OPC server. So the benefit of the NI OPC server is not limited to two types of PLC used right now but can also use the other manufacturers. Besides, the improvement of the previous study is the use of the LabVIEW makes data from the OPC server displayed more realistic. The use of LabVIEW allows additional monitoring functions, one of which is LabVIEW vision. Data utilization becomes more flexible, and so it can use for more complex purposes. It is envisaged that this is very useful for Integrator engineer to implement this method in industrial automation</span>

Supervision, control, and data acquisition system of a heat exchanger

“…With respect to the use of a Siemes 1214C programmable logic controller, it allowed the control of actuators and sensors, guaranteeing the regulation and control of temperatures in the heat exchanger; In this regard, in [29] and [30], although they manage to perform temperature control in a heat exchanger of the same type, they mention that they do it using PID controllers; Rather than disagree regarding the type of approach used, from my perspective our proposals are not far from this because the Siemens 1214C programmable controller has a PID function block, which can also be used as a contingency or parallel alternative; However, the contribution is that it is being shown that both architectures are valid for the control of a heat exchanger. In relation to the acquisition and monitoring of data through the HMI interface, it was possible to perform the acquisition and monitoring of data in an optimal way; In this regard, in [33] he refers to the use of an HMI interface, specifying that it is convenient from the point of view of the historical record of alterations of the temperature variable under study, that this interface contains both graphic and numerical components; In this regard, we agree on this type of approach since what is sought through this interface is to have a representation of the behavior of the system, it will not necessarily be located in places close to the plant or process, so many times the HMI interface It is found in places distant from the process, so it must be strictly used to show information through graphics and its variations in real time.…”

“…Sánchez et al [32] it is described that it was possible to develop a neural network algorithm from the acquisition of data through a SCADA system from a heat exchanger system, evidence that the monitoring allowed to obtain the data permanently by monitoring the variables of the process (temperature), achieving a high performance of the neural network. In the same line of research [33] shows a predictive maintenance model is developed, which guarantees the optimal operation Indonesian J Elec Eng & Comp Sci ISSN: 2502-4752  Supervision, control and data acquisition system of a heat exchanger (Martín Díaz-Choque) 157 of a refrigeration system and temperature exchange in the process, from the integration of a SCADA system with sensors implemented through Arduino. Fareeza et al [34] the author points out that generating information through supervision and monitoring systems of an industrial process guarantees the flexibility of the system, since from these data the presence of some anomalies or failures can be foreseen as part of the process of some kind of disturbance, which will allow the parameters inherent to the industrial process to be corrected opportunely.…”

Design and implementation of a control system for a steel plate cutting production line using programmable logic controller

“…The programming method used is the ladder diagram (LAD) method. The designing LAD can be running and verifying by a personal computer [25]. PLC takes the sensors signal and processed them by the program then gives the signal to the VFD which again processes this input signals and finally controlling the motor speed.…”
