Section 5. System Overview 5.1.9.2 Modbus Read More! See Modbus (p. 350). The CR800 supports Modbus master and Modbus slave communication for inclusion in Modbus SCADA networks. 5.1.9.3 DNP3 Communication Read More! See DNP3 (p. 347). The CR800 supports DNP3 slave communication for inclusion in DNP3 SCADA networks. 5.1.9.4 Keyboard Display Read More! See Using the Keyboard Display (p. 382). The external 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. 5.1.9.4.1 Custom Menus Read More! To implement custom menus, see CRBasic Editor Help for the DisplayMenu() instruction. CRBasic programming in the CR800 facilitates creation of custom menus for the external 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 displays two values from CR800 memory. PanelTemps shows the CR800 wiringpanel temperature at each scan, and the one-minute sample of panel temperature. TCTemps displays two thermocouple temperatures. 69
