Today’s Q&A is with Tyler Jang – Technical Field Solutions Manager, USA. He’s been with SIGIT since 2014, and we’re grateful for all he does. He’s been dubbed “The IT Guy” – not ‘IT’ solely because of his data and communications expertise… More so, if you have an obscure or complicated question – he’s going to solve IT.
Q) What is your approach to designing a SCADA system?
A) First is understanding the business workflows from the field to enterprise. If you do not know what data you want, you cannot create useful data flows to make decisions on. Find out what the business needs and what pressure points exist when they cannot get the data or control. From there, you can design a framework on how to get data from A to B and create interfaces for both operations and enterprise to use.
Q) Why should I use a database-driven HMI or SCADA system?
A) When upgrading or choosing a new system, companies are looking for more functionality. The days of plant HMIs and SCADA systems only being used by plant operators are gone. More parties want access to the data now, and they all want it at the same time. Using databases will allow more customization to the system and allow multiple parties to access and analyze data in real-time.
Q) Why are networks so important in a SCADA system?
A) Networking is your nervous system of any control system. Without it, you cannot function. Regardless of the system used, if the data stops, so does the process. Many modern systems rely so heavily on network communications, that the network uptime is more important than the actual control system. There are many ways to increase the reliability and stability of a network.
Q) What is one thing you think you do differently than everyone else?
A) I think about the data. In the end, the user wants data on screen, in reports, and they want it now. I look at the process and find out what the stakeholders want and need. Then, I build the system that delivers. I will not allow hardware and software packages to limit the data the customer is asking for. I work with common sense solutions to allow the customer to make quick and proactive decisions to help their business.
Q) What is one thing the client can count on you for?
A) You can count on me to deliver a solution you need. Creating realistic expectations is key to a successful project. This does not mean lowering expectations, but understanding the limitations of the process and systems in place. My job is to create solutions to the pressure points of a business and make it easier. Delivering what the customer needs and not trying to upsell unnecessary products will always help the relationship with the customer.
