5-64 C30 Controller System GE Multilin5.2 PRODUCT SETUP 5 SETTINGS5This feature provides a mechanism where any of 256 selected FlexLogic operand states can be used for efficient monitor-ing. The feature allows user-customized access to the FlexLogic operand states in the relay. The state bits are packed sothat 16 states may be read out in a single Modbus register. The state bits can be configured so that all of the states whichare of interest to the user are available in a minimum number of Modbus registers.The state bits may be read out in the “Flex States” register array beginning at Modbus address 0900h. Sixteen states arepacked into each register, with the lowest-numbered state in the lowest-order bit. There are sixteen registers to accommo-date the 256 state bits.5.2.15 USER-DEFINABLE DISPLAYSa) MAIN MENUPATH: SETTINGS PRODUCT SETUP USER-DEFINABLE DISPLAYSThis menu provides a mechanism for manually creating up to 16 user-defined information displays in a convenient viewingsequence in the USER DISPLAYS menu (between the TARGETS and ACTUAL VALUES top-level menus). The sub-menus facili-tate text entry and Modbus register data pointer options for defining the user display content.Once programmed, the user-definable displays can be viewed in two ways.• KEYPAD: Use the MENU key to select the USER DISPLAYS menu item to access the first user-definable display (notethat only the programmed screens are displayed). The screens can be scrolled using the UP and DOWN keys. Thedisplay disappears after the default message time-out period specified by the PRODUCT SETUP DISPLAY PROPER-TIES DEFAULT MESSAGE TIMEOUT setting.• USER-PROGRAMMABLE CONTROL INPUT: The user-definable displays also respond to the INVOKE AND SCROLLsetting. Any FlexLogic operand (in particular, the user-programmable pushbutton operands), can be used to navigatethe programmed displays.On the rising edge of the configured operand (such as when the pushbutton is pressed), the displays are invoked byshowing the last user-definable display shown during the previous activity. From this moment onward, the operandacts exactly as the down key and allows scrolling through the configured displays. The last display wraps up to the firstone. The INVOKE AND SCROLL input and the DOWN key operate concurrently.When the default timer expires (set by the DEFAULT MESSAGE TIMEOUT setting), the relay will start to cycle through theuser displays. The next activity of the INVOKE AND SCROLL input stops the cycling at the currently displayed user dis-play, not at the first user-defined display. The INVOKE AND SCROLL pulses must last for at least 250 ms to take effect.
