M90/M91by UnitronicsThe M90/M91™ is an innovative micro-PLC (Programmable Logic Controller) with a built-in operating panel. The operating panel offers an LCD that can display two 16-character text lines, and a keypad (one line in the M90 models). The M90/M91™ series offers a variety of onboard I/O configurations, including direct temperature and weight measurement inputs; the configuration can be expanded by adding I/O Expansion Modules. The M90/M91™ is the perfect control solution for small-to-medium applications such as water treatment, automated machines, and process control. Benefits Save our customers programming time, wiring, and cabinet space Cut budget by reducing requirements for additional hardware Prevent you from wasting time setting up Panel-PLC communication Specifications PLC Up to 38 onboard I/Os: Digital, Analog and temperature measurement inputs, Relay or Transistor outputs Shaft encoder inputs and PWM outputs I/O Expansion Modules: enable up to 96 digital I/Os plus additional analog, temperature and weight inputs (number/type vary according to model) RTC, enabling time-and-date controlled operations 24K-36K (virtual) Ladder code capacity Functions include: math, store/load, compare, and clock functions, plus immediate read/write to I/Os, interrupts and loops 1K database 4 PID loops including auto-tune Mounting: Panel or DIN-rail HMI Two 16-character text lines, LCD illuminated screen Alphanumeric 16-key keypad, for data entry and to initiate tasks Multilingual display - supports over 15 languages Up to 80 user-designed screens, displays conditional messages Display conditional text, time, date, bit status, timer & integer values (up to 64 HMI variables per application) "List" variables: link up to 150 messages to a single variable, to add 2K's of conditional text. "List" variables allow easy scrolling between recipes/menus via the keypad Info mode: view I/O status, integer values, and system data on the LCD display Communications RS232 or RS232/RS485 serial communication port GSM/SMS support Remote access via network GPRS, GSM, CDMA or landline modems Data Export to/from Excel MODBUS (master/slave) CANbus port (model dependent) OPC/DDE server Special Features Flexible PID m: Accurate process control—plus all the advantages of flexible PLC programming. M91 controllers enable you to take control with 4 built-in PID loops, including auto-tune. Database: Log production quantities, monitor temperatures, or record any type of required data with the embedded 1024 integer database. Shaft-encoder Inputs: Use the controller’s integral 10kHz inputs as high-speed counters, frequency measurers, or to directly connect to shaft-encoders. PWM Outputs: Control stepper motors or PID-based applications, via PWM, with the M90/91’s onboard PWM outputs (model-dependent). Easy Scrolling between Recipes: Simply scroll between pre-programmed recipes or menus, using the panel’s arrow keys. This enables you to choose and activate a desired task via the HMI - immediately, on-site. Upload: Full source, password-protected upload option enables you to restore the application, as if it was just saved on your PC (including comments and symbols). Temperature & Weight measurement: Onboard direct temperature inputs (PT100 or Thermocouple) give you the ability to control temperature-based applications, Loadcell I/O Expansion Modules enable you to hook up weight/strain inputs and achieve accurate measurements—no additional hardware required. (M91 series only, features are model-dependant). Multilingual Display: Our PLC textual displays support over 15 languages. Graphical displays support any language, according to the fonts installed in your version of Windows. Print Utility: Log system data or events-on paper. Unitronics PLCs can send scheduled or event-provoked messages to a serial printer, either directly or via modem. Time-based Control: Do you need a specific task to be performed at a specific time and date? Simply mark the hour, date or weekday in the PLC software—and you have created time-based control in 3 clicks. Information Mode: Press the key on the operator panel to enter the PLC’s Information Mode, providing you with powerful diagnostic capabilities. Software All-in-one software enables you to develop your PLC and HMI applications in one environment, establish modem and data communications, test and debug your programs in on-line mode, remotely access your controller, and more.
