6 (Total output 150 mA max. from ports A and B)Dedicated connectorNote When using the +5 V output of pin No. 6, check that the total current required by the devices connected toports A and B is less than 150 mA. The NT21 supplies +5 V "5% (150 mA max.) to pin 6 of these ports.188Appendix ASpecificationsProgramming EnvironmentItemSpecificationProgramming SystemProgramming Support SoftwareProgramming DeviceProgramming Support Software: NT-series Support Tool for Windows (Ver. 5), by OMRONSpecial FeaturesItemSpecificationsBuzzerThree kinds of buzzer sound (continuous, short intermittent, and long intermittent)Sounds:On reception of a command from the host, display of a screen with abuzzer setting, or display of an error screen such as for a receive error.Stops:On reception of a command from the host, or display of a screen withno buzzer setting.Setting:Set “ON” for “Buzzer Sound” in the memory switch menu, or set“ERROR ON” for the buzzer to sound only when an error occurs.The buzzer sounds three times in response to prohibited input.Touch switch input soundTouch switchesInput sound: Sounding for 0.2 secondsSetting:Set “ON” for “Key Press Sound” in the memory switch menu.Maintenance function- Memory switch setting- Self-test functions, such as for the memory and external interface- Setting condition confirmation function- Communication check function- Initialization of internal memory data- Display of display/alarm history data- Registered data test display functionBattery backup (optional)- Backup of numeral/character string memory table data in the NT21- Backup of display/alarm history data- Backup of recipe dataBattery life:5 years (at 25_C)When voltage becomes low: RUN Indicator lights in orange or redThe communication flag to the PC (BAT LOW) isturned ON (1).Resume function(Operates only when theoptional battery is installed.)Retains the contents of the numeral and character string memory tables (i.e., theyare not initialized) when the NT21 is turned ON or the operation mode is changed.Setting:Set “ON” for “Resume Function” in the memory switch menu.Calendar and clock function- Displays the date and time read from the PC.- Display the date and time with the “Calendar Check” operation.Programming Console functionExecutes functions equivalent to those of a C200H-PRO27-E Programming Consolefor CPM1, CPM1A, CPM2A, CPM2C, CQM1 (-EV1 only), CQM1H,C200HX/HG/HE(-Z)E, and SRM1 (C02-V2 only) PCs.Executes functions as a Programming Console for CS/CJ-series PC.Mathematical functionTransmissionfunctionsUp to 256 calculation expressions can be registered along with the screen data.
Thecalculation function reads the required data from the numeral memory table or hostwords, executes the registered calculations, and writes the results.Arithmetic operators, logic operators, bit operators, and comparative operators canbe used.System programtransmissionDownloads the system program from the system installer.Downloads/Upload the system program with a Memory Unit.Screen datatransmission- Function for downloading screen data to and uploading screen data from theNT Support Tool- Function for transmitting screen data to and from the Memory Unit.History datauploadingFunction for uploading display/alarm history data from PT.189Appendix ASpecificationsCommunications SpecificationsSpecifications for Host Link CommunicationsItemSpecificationCommunications standardEIA RS-232CCommunications settingsStart-stop synchronizationBaud rate:Data length:Stop bits:Parity:Connector9-pin D-SUB connectors (female) (serial ports A and B)Number of Units connected1:1Transmission distanceMax.
