Section 7. Installation For more detailed information on Network Planner, please consult the LoggerNet manual, which is available at www.campbellsci.com. 7.6.3.5.2 Basics PakBus Settings • Device addresses are automatically allocated but can be changed. • Device connections are used to determine whether neighbor lists should be specified. • Verification intervals will depend on the activities between devices. • Beacon intervals will be assigned but will have default values. • Network role (e.g., router or leaf node) will be assigned based on device links. Device Links and Communication Resources • Disallow links that will not work. • Comparative desirability of links. • Prevent over-allocation of resources. • Optimal RS-232 and CS I/O ME baud rates based on device links. • Optimal packet size limits based upon anticipated routes. Fundamentals of Planning a Network • Add a background (optional). • Place stations, peripherals, etc. • Establish links. • Set up activities (scheduled poll, callback). • Configure devices. • Configure LoggerNet (adds the planned network to the LoggerNet Network Map). 7.7 Programming Programs are created with either Short Cut (p. 443) or CRBasic Editor (p. 109). Programs can be up to 490 kB in size; most programs, however, are much smaller. 7.7.1 Writing and Editing Programs 7.7.1.1 Short Cut Editor and Program Generator Short Cut is easy-to-use, menu-driven software that presents the user with lists of predefined measurement, processing, and control algorithms from which to choose. The user makes choices, and Short Cut writes the CRBasic code required to perform the tasks. Short Cut creates a wiring diagram to simplify connection of 108
