Manage your KPIs over the Web and Smartphones

摘要

This paper will give three "real-world" examples of using the web and smartphones to allow plant operators, engineers, and managers to take the plant HMI with them when they leave the control room, the plant, and even the town or continent. Session attendees will be given a step-by-step process to translate their HMI displays to the web and/or their smartphones. This paper which can be given as a tutorial will have hardware and software available to allow attendees to actually see how to program the systems. This paper and the associated tutorial will show the reader and/or tutorial attendee how to design, program, implement, and troubleshoot the equipment from representative vendors by showing the respective software used to program and communicate with each of the hardware devices with screen prints from the programs as well as sample third-party interface software (i.e.; HMI's) that can be used by operators, technicians, engineers, and managers. In this paper and tutorial, Modbus TCP and OPC communication will be used. The hardware used for the tutorial are all commercially, off-the-shelf (COTF) that all have long and successful histories of providing industrially-proven instrumentation controllers, signal conversion devices, isolators, and connectors to both end-users and OEM manufacturers. In this tutorial Microsoft Windows- and Apple iOS-based software is used to communicate with and program each of the equipment. In the following pages, screen prints from the programs will show the basic steps necessary to bring the hardware and software into operation. With the many instrument & control vendors offering these relatively low-cost, modular, ethernet I/O systems that can be configured quickly and communicate with each other AND other computers with off-the-shelf ethernet hubs, switches, and/or routers the internet can be used as a method of bringing field devices from your plant into a computer SCADA or control system and viewed from a browser or application across the ethernet, sometimes VERY remotely using private and/or public addresses via Wi-Fi and/or cellular technology to extend the ethernet to remote field devices. Hopefully this tutorial has provided a starting point for the industrial automation professional beginning a long study and career implementing applications on tablets and smartphones. In this author's opinion, the future of industrial instrumentation and automation visualization will surely move toward greater use of industrial wireless1 and cellular ethernet for communication between devices, controllers, operator interfaces, and maintenance tools. Currently, many instrument & control vendors offer modular, ethernet I/O and visualization systems that can be used as a relatively low-cost method of bringing field devices from your plant into a computer SCADA or control system via the ethernet. These systems can be configured quickly and communicate with each other AND other computers over standard ethernet using off-the-shelf ethernet hubs, switches, and/or routers and viewed from a browser, a spreadsheet, or HMI on mobile devices like smartphones, iPads, and tablets. Learn how to configure AND implement ethernet I/O systems for your plant. This tutorial will have hardware and software to allow attendees to actually program the systems.
