Webinar Recap: Front-End Loading for Control System Migration

Posted by Paul Galeski on June 2, 2014 @ 3:11 pm

Webinar Recap: Front-End Loading for Control System Migration We’re glad so many of you could join us for the Front-End Loading (FEL) webinar on Thursday! Speakers Nick Sands, Matt Sigmon and Charles Skeen addressed a number of common migration concerns and shared how a three-step FEL process can help minimize risk and identify potential process improvements. If you couldn’t make it to the webinar, here’s a brief recap of what you missed: The Project Dilemma Do you want your project done fast, cheap or well? Without FEL, you’ll be facing challenges with all three. And the further along you get, the more expensive it becomes to make changes to your initial project plan. The most common mistake that occurs in the absence of front-end loading is the failure to establish complete requirements for systems and control functions. “Going ah... Continue Reading

Programming PLCs: Keep the documentation clear and simple

Posted by Miguel Gutierrez on May 21, 2014 @ 10:24 am

Poor programmable logic controller documentation and housekeeping can lead to unnecessary troubleshooting and downtime. Keep it simple in order to avoid the possible risks and confusion.

There are different rules and programming methods that are needed based on the hardware and software being used. Programming in a Siemens programmable logic controller (PLC) is not identical to programming in an Allen-Bradley PLC. There are general good practices that should be followed in any programming. The obvious is to have the program function and control as desired. Maintaining good documentation and housekeeping are good general practices in programming. Code should be easily read and understood by programming colleagues and customers. Poor documentation and housekeeping can add unnecessary time to troubleshooting, downtime, and programming. Programming structure... Continue Reading

Power fail-safe state: After the power outage

Posted by Robert Henderson on May 13, 2014 @ 10:20 am

Identifying a power outage – small or large – is only a fraction of the battle for your equipment.

After your power fails, the system is down and no energy was released in a way that endangered people or property. Good job. Now what? Blip! The power just came back. Now we have to deal with the aftermath of the po... Continue Reading

DCS migration: Batch or S88 style application?

Posted by Bruce Brandt on May 8, 2014 @ 3:54 pm

Deciding between a dedicated batch application and building an S88 style application really comes down to the level of sophistication required to make the system user-friendly and supportable by the plant.

I just finished supporting a batch process startup where the client chose to not continue using the same batch application as the rest of their facility. This plant area had previously been controlled by a programmable logic controller (PLC) using some basic sequencing. The project was to migrate it to a distributed control system (DCS) that has already been used in other parts of the plant. Some of the other areas that have been migrated are using the batch software application, but because this process is rather basic it was decided that using the DCS batch software was overkill. Therefore, the migration was done using Sequential function chart-based... Continue Reading

Exclusive Webinar: Front-end Loading for Control System Migration

Posted by MAVERICK Leadership Team on May 5, 2014 @ 2:20 pm

Exclusive Webinar: Front-end Loading for Control System Migration May 29, 2014 12 p.m. EST (9 a.m. PST) Brought to you by ISA and MAVERICK Technologies Your control system was originally designed to meet your plant’s specific needs, but considering how much those needs have changed over the years, has it really kept up? Performing a major upgrade on your control system can be intimidating. And with good reason — it’s a monumental decision that’s not without risks. That’s why, before you can begin, you have to pre-plan. Front-end loading (FEL) the engineering requirements and design phase will significantly reduce the amount of time, effort and money spent on the project. Even more importantly, it can prevent catastrophic mistakes. Continue Reading
