I am concerned about a lack of advances in PC based HMI/SCADA. As I see it, the vendors of the most heavily used HMI products have shifted their focus away from developing solid, continuous-use software for monitoring and control. They now seem possessed with the concept of "enterprise integration". While this is important, it is offered at the expense of basic HMI capability. In fact, it seems that significant HMI software enhancement stopped some years ago. The number of innovative features added in the last five years can be counted on one hand. Support for OLE technologies (ActiveX Controls, OPC) and some vendors selection of VBA as a scripting language are examples (honorable mention to Wizards and Dynamos). The bulk of the HMI/SCADA market is held [captive?] by two or three vendors that continue to offer largely cosmetic changes to the same software. Meanwhile, industrial automation installations are growing larger, involving higher I/O counts, and a larger number of controllers and networks. Technology as a whole is advancing at an ever accelerating rate, and in particular, state-of-the-art software tools and technologies are experiencing an almost complete shift from where they were just a few years ago. I fear the automation community is saddled with HMI solutions that are not keeping pace with the growth in automation systems, advanced software technologies, and exclude the use of "enterprise integration" solutions not controlled by the HMI provider. With this as a premise, I hope you will engage me in a [lively] discussion focusing on the future of HMI and SCADA. How do you feel about your choices for HMI today? Do you value the "enterprise" solutions from these vendors? Have you used or seen an HMI offering truly innovative features? Am I completely wrong? Is HMI just a word processor now, and all you want is to type your document? Where do we go from here? Thank you, Jeff Dean [email protected] For the sake of full disclosure, I am not an employee of any HMI vendor, though I have been in the past. My work still involves automation - software development for integrators. Additionally, these are my opinions and they do not necessarily reflect those of my employer, or anyone else for that matter.
