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

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

New ideas for quality management: Part 6

Posted by John Clemons on April 23, 2014 @ 10:02 am

Managing manufacturing quality is never a one-size-fits-all solution. Each situation differs and requires unique approaches to technologies, information, and training.

As I promised last time, I’m finally wrapping up this topic on the management of manufacturing quality. If you’ve been following all this, you’ll know that there are a lot of cool new ideas out there and a lot of cool new technology as well. It all means that you can have a pretty big impact on the shop floor and a pretty big impact on the bottom line for your company. What I thought I’d do with this post is try to wrap up this topic and try to give you a bit of a road map on how to make some changes, and how to get from where you are to where you want to be. But before I start I guess I need to mention a few things. First, this isn’t a one-size-fits-all solution. This road map is just a suggestio... Continue Reading
