Technology Update: SCADA evolves toward MES

Today's SCADA systems are evolving beyond supervisory control and data acquisition with greater functionalities and integration capabilities.
In Food Engineering's 2001 Best Manufacturing Practices Survey (Feb., '01), only five percent of respondents reported having SCADA systems in their plants.
We thought that surprisingly low. The problem may lie in the definition.
SCADA -- the acronym and abbreviation for Supervisory Control And Data Acquisition -- has become more difficult to define as these systems add more production-management and manufacturing-execution functions, blurring the distinction between SCADA and MES (Manufacturing Execution Systems).
The term SCADA emerged during the 1980s from the gas, oil and utilities industries, where it refers to remote monitoring and control of widely distributed plcs and I/O points in facilities such as oil fields, electric-power generating stations, water and wastewater-treatment plants. Eventually the term was applied in manu…

How do you integrate an existing WinCC project into a STEP 7 project?

Configuration Notes:The following WinCC components must be installed to be able to import a WinCC project into a STEP 7 project:
SIMATIC Device Drivers Object Manager AS-OS Engineering These components are on the WinCC Installations CD (Fig. 01). Furthermore, WinCC and STEP 7 have to be installed on the same computer. By importing the WinCC project into a STEP 7 project you can use the existing compression tool (packer) for archiving the WinCC project.

Where are Standards Headed?

The merging of EN ISO 13849 and IEC 62061 is underway. Navigate the path to unification and find out how it will be an opportunity for clarification, simplification and resolution of known issues.

What do you think about machinery safety standards? Are they a help or a hindrance?
There doesn’t seem to be much middle ground in answers to these questions. You either love machinery safety standards or hate them. If you have no real opinion, it’s probably because you never have to use them. However, if you’re reading this, you’re probably among the chosen ones who must use them, and you need to know what standards are out there and which changes are going to appear over the horizon.
That can be easier said than done, especially if you’re taking a global perspective. Trying to match different standards to various geographies can be frustrating and time-consuming. The increasing worldwide adoption of ISO and IEC…
