Here are some thoughts on the use of the Internet in manufacturing.
1. Data collection is key. As the workforce resource is stretched to its limit, access to data can help increase productivity without taxing the worker to fill in manual reports.
2. Diagnostic information: Wireless has some benefits. A machine that can email a maintenance request to a computer or cell phone/text pager can save several trips only to obtain the correct tool or replacement parts.
3. Remote status/operation is beneficial in many ways:
- Picture a pipeline pumping station or even a large process-type application. No person must travel miles upon miles to a remote site only to take readings. An html-based HMI can save time and irritation.
- An OEM will typically make a machine for a widget manufacturer. The widget manufacturer may not have a controls engineer on staff. A Web-based HMI/controller can allow an OEM to go above and beyond phone support by viewing the status of a machine from many miles away (or even in another country). Telephones are not available on every manufacturing floor and cell phone service leaves a lot to be desired; Ethernet (wired or wireless) can come to the rescue. Xycom Automation's GP-Web product allows someone to view and optionally interact with remote machinery, over the Internet or via an Intranet, using only a standard Web browser.
- Ethernet and the various open technologies can improve hazardous location or clean room interaction via a remote monitor.
- Remote engineering can reduce the manhours involved in analysis, report writing, and traveling. According to the Research Study of Multimedia Applications in Open FA Systems, by the Japan FA Open Systems Promotion Group (JOP)/Manufacturing Science and Technology Center (MSTC) (1999), remote engineering can save as much as 82 minutes of problem analysis, 39 minutes of report writing, and 130 minutes in travel time.
4. Wireless Ethernet has allowed fork truck operators to get their next pickup orders via a screen onboard without having to return to a central location for directions.
5. System Structure: The graphic provides an example "System Structure" for an Internet/Intranet layout.
