Section 5. System Overview • Routing - the CR3000 can act as a router, passing on messages intended for another logger. PakBus supports automatic route detection and selection. • Short distance networks with no extra hardware --a CR3000 can talk to another CR3000 over distances up to 30 feet by connecting transmit, receive and ground wires between the dataloggers. PC communications with a PakBus datalogger via the CS I/O port, over phone modem or radio, can be routed to other PakBus dataloggers. • Datalogger to datalogger communications - special CRBasic instructions simplify transferring data between dataloggers for distributed decision making or control. • In a PakBus network, each datalogger is set to a unique address before being installed. The default PakBus address in most devices is 1. To communicate with the CR3000, the datalogger support software (p. 76) must know the CR3000 PakBus address. The PakBus address is changed using the integrated keyboard / display (p. 404), DevConfig utility (p. 97), CR3000 Status table (p. 530), or PakBus Graph (p. 463) software. 5.1.8.2 Modbus Read More! See Modbus (p. 372). The CR3000 supports Modbus master and Modbus slave communication for inclusion in Modbus SCADA networks. 5.1.8.3 DNP3 Communication Read More! See DNP3 (p. 369). The CR3000 supports DNP3 slave communication for inclusion in DNP3 SCADA networks. 5.1.8.4 Keyboard Display Read More! See Using the Keyboard Display (p. 404). The integrated keyboard / display is a powerful tool for field use. It allows complete access to most datalogger tables and functions, which allow the user to monitor, make modifications, and troubleshoot a datalogger installation conveniently and in most weather conditions. 5.1.8.4.1 Custom Menus Read More! To implement custom menus, see CRBasic Editor Help for the DisplayMenu() instruction. CRBasic programming in the CR3000 facilitates creation of custom menus for the integrated keyboard / display. Figure Custom Menu Example (p. 70) shows windows from a simple custom menu named DataView. DataView appears as the main menu on the keyboard display. DataView has menu item Counter, and submenus PanelTemps, TCTemps and System Menu. Counter allows selection of one of four values. Each submenu 69
