7 This includes remote (from cli-ent) access to Control functions such as motor start/stop andcontroller set point and output changes. Therefore, make sure thatwhen you enable this option, you are careful in assigning LAN-90 PCV accounts and permissions. (p. 3-1)Care must be used when assigning an IP address to a node on aTCP/IP network. Avoid duplicating IP addresses. Note that some IPaddresses are reserved , and that addresses in different rangeswill sometimes have different behaviors. Consult the documentationthat came with your TCP/IP software for more details. (p. 3-2)Extreme caution should be used when embedding Control -typefunctionality into spreadsheet macros. Make sure that any macrosyou set up are protected from improper use, and well documentedas to their functionality. It is not a good idea to have Control -typemacros execute automatically when a spreadsheet is opened,because someone browsing through spreadsheet files may acci-dentally invoke a Control operation.

9 Using this product, you can incorporate livedata into reports and spreadsheets, set up using your favoritethird party package, and actually watch the values change inreal-time. Alternatively, historical information collected byLAN-90 PCV can be viewed. This information can be incorpo-rated into any of the many Microsoft Windows applicationsthat support the DDE data communication standard, such asMicrosoft Excel , Microsoft Word for Windows, and WordPer-fect , with no more effort than a few clicks of the desired, systems can be configured that actually allow datato be sent back to the LAN-90 PCV system from the MicrosoftWindows computer system. This can be used to change inter-nal PCV values, or even perform some Control functions. Ofcourse, if you want to perform these types of functions you willhave to be pre-qualified through the standard LAN-90 PCVpassword protection mechanism, which classCONNECT/DDEinterfaces shown in Figure 1-1, classCONNECT/DDE works in con-junction with the LAN-90 PCV TCP-Link software provides the services necessary on the LAN-90 PCVconsole to communicate with the classCONNECT/DDE soft-ware modules.

10 Communications between these two packagesis done via a standard TCP/IP Local Area Network interfaceover Ethernet .classCONNECT/DDE conforms to the DDE standards as setout by Microsoft. This allows you to work with a large numberof applications from numerous vendors. The classCONNECT/DDE server has been tested with both Microsoft Excel andMicrosoft Word using the examples included in the applications that claim to support DDE do not support itfully, however, and therefore may not function as well as theyshould. While we cannot guarantee that any other applicationwill function as flawlessly, through our Professional Servicesprogram we offer whatever level of support you require to inte-grate your applications with classCONNECT/DDE.
