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

Upgrading control systems: Phase migration vs. complete replacement

Posted by Dave Cortivo on April 30, 2014 @ 12:30 pm

After receiving the approval for a control system replacement project, how do you decide between phased migration and a complete replacement? Do you keep some of the old and integrate the new, or just go with a fresh start?

Now it’s t... 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

New ideas for quality management: Part 5

Posted by John Clemons on April 16, 2014 @ 2:53 pm

By implementing a process of testing rationalization whereby only a minimal number of tests are actually run and more tests are run only when problems occur, a process of management by exception may be implemented.

Well, I thought I was wrapping up these on the new ideas for quality management, but I’ve thought of a few more things that I’d like to talk about. The last couple of posts we talked about technology and all the cool technology that’s out there to support the management of manufacturing quality. But I think I would be remiss here if I didn’t mention a few things about business processes that are needed to support manufacturing quality management. And, some of these processes are pretty new as well. First is adopting the concept or business process of multi-level testing. The idea is that the initial level of testing is to monitor the process and make s... Continue Reading
