2600T Series Pressure transmitters | OI/266/FF-EN Rev. B 3710 HMI local indicator10.6 LCD structureThe Device TAG and Node Address are always visible in thetop side of the LCD. The line/s and bar-graph view depends bythe HMI_MODE SelectionThe displayed variables are identified by a max of the threecharacter strings visible on the left side of the value when twolines mode is selected or below the value when one line modeis selected. The list of all the strings identifying the variable isavailable in the HMI_VARIABLE_1 within the HMITB table, see“APPENDIX A – Device Data Blocks”.Example of how the indicator looks with one and twolines plus bar-graph1 Tag | 2 Node address | 3 Variable identification | 4 Line 1 |5 Line 2 | 6 Bar-graph10.7 LCD settingThe variables to be displayed can be selected in two ways:— Locally using the optional LCD keypad from the menu“Display/settings/…” see APPENDIX B for furtherinformation.— From remote station via Fieldbus communication writingin the HMITB.In the HMITB there are up to 4 variables called HMI_VARIABLE_x (where x is from 1 to 4) and each of them can beset with one variable to be displayed, selected from a list of 10different variables.Then the HMI_LINE_1, HMI_LINE_2 and HMI_BARGRAPHmust be set to one of the HMI_VARIABLE_x depending bywhich variable the user wants see on the Line 1 or Line 2 orbar-graph. The parameter HMI_SEQUENCE allows theenabling of the automatic scrolling of the 4 HMI_VARIABLE_x31 23 456Figure 47: Display layoutImportant. It is recommended to use the Auto-scrolling only withHMI_MODE set to One Line..10.8 HMI as Diagnostic IndicatorWhile the HMI works as Variable Indicator, also diagnosticstrings can be displayed. Whenever a failure or warningcondition is detected within the transmitter, a message appearsin the low side of the display below the bar-graph.The message is formed by the NAMUR NE107 icon and thestring of the component where the problem occurred.NAMUR icons Description Source of errorError / Failure ELECTRONICSFunctional check (e.g. duringsimulation ) SENSOROut of Spec (e.g. Sensor temperatureoutside the specs limits) PROCESSMaintenance required CONFIGURATIONExample of “Maintenance / Sensor” and “Failure /Electronics” diagnosticFigure 48: Diagnostic messages
