Why Should I Upgrade to a Program Logic Controller (PLC)?

Why automate, why improve? They’re all about the same question, so after covering the more general area, we’ll zoom in on the specifics of PLCs. “Why improve?” Because your competitors are, and you will not be in competition with them very long, if you don’t. “More and better” are today’s bottom line. With the customers being better educated, and having better availability of the product they seek, you have no choice.

Maintenance Management of Your Company’s PLC (Programmable Logic Controller)

You need to read this article on maintenance management of PLCs. Why? Because the PLCs (Programmable Logic Controllers) are the brains of your operation. When the PLC is not functioning properly, lines shut down, plants shutdown, even city bridges and water stations could cease to operate. Thousands to millions could be lost by one little PLC in an electrical panel that you never even knew existed. But most importantly, damage to machine and personnel could result from improper maintenance management of your company’s PLCs.

Magnifying Mini: Microelectronics Miniaturization

One of the most pervasive trends in fluid handling today is that of miniaturization. The call for smaller and smaller flow control devices is evident across the industry. Regarding hydraulic and pneumatic components specifically, the extraordinary mass-to-power and mass-to-response features of such technologies are enabling miniaturization.1 But as hydraulic and pneumatic devices continue to go mini, the manufacturing process has become more finite and certain design vulnerabilities have become more pronounced.

Maintaining Process Control Field Devices

It is not necessary to totally restructure maintenance practices. A plant can start small and expand the use of process floor information as needs dictate and budgets allow. The key is to begin building a database from the smart devices now in operation and expand the use of the available information as the number of such devices grows. A scalable and expandable platform can grow into a plantwide system that supports the reliability and maintainability of all field instrumentation.

Protecting Mission Critical Electronics

Today’s new control systems are delivering higher productivity to meet ever-increasing expectations of equipment performance. These systems typically contain more electronics, much of it adopted from non-industrial applications, and almost all of it more sensitive to electrical disturbances than the equipment being replaced. The following discussion provides information needed to develop a strategy for protecting sensitive mission critical equipment from the effects of a poor industrial power environment.

Critical Component of the CMMS: The Repair Work Order

From the very start, the implementation of a computerized maintenance management system (CMMS) is a long and arduous process. One of the largest concerns is how to effectively get the correct data into the system in the first place, and then, how to get useful information out. The better and more consistently recording of repair activities is done, the greater potential for yielding greater and more specific information about an operation.

How Project Management Software Can Smooth the Way

Scheduled shutdowns, however, can provide unique opportunities to a maintenance department not normally available during standard operation or even during short shutdown periods. Lost capacity can be restored to an overtaxed facility during an extended shutdown. Major equipment overhauls can be performed to help prevent future unscheduled shutdowns. Government mandated inspections and repairs can be accomplished during a shutdown, bringing a plant into better compliance.

The Achilles Heel of Modern Electronics

Digital measurement technology certainly has taken the test industry forward, mostly with giant strides. The exact opposite may be true, however, when it is applied to testing for aging-related failure modes such as intermittency or no fault found (NFF). Digital abstraction devices, perfect for parametric testing, rarely synchronize to real-time, randomly occurring, anomalous, or intermittent age-related failure events. This shortcoming is especially acute when large numbers of circuit nodes require testing.

Maintenance Software (CMMS) Implementation

Much has been written in the past about the implementation of maintenance software (CMMS systems). This article takes a slightly different approach in that it attempts to explain some of the pitfalls associated with first time implementation in SME’s. It suggests a “try before you buy” approach, which stages the maintenance software implementation to reduce both risk and cost. Tales of failed implementations abound and failure rates of 40% to 80% are commonly quoted. Real statistics are hard to come by but the following data is both relevant and current.
