      UniStream 5" CX Modules

      A new line of I/O adapters and COM modules, the CX series, has been created. These are compatible with the UniStream 5":

      ·         UAG-CX-xxx I/O Expansion Adapters plug into the UniStream 5” I/O Expansion Jack, and enables you to link standard Uni-I/O modules to the controller. Installation instructions and guidelines on installation and number of supported I/O modules are in the product’s Installation guides and technical specifications.

      ·         Three UAC-CX-xxx COM Modules are now available:
      - UAC-CX-01RS2 offers one RS232 port
      - UAC-CX-01RS4 offers one RS485 port
      - UAC-CX-01CAN offers one CANbus port.
      Installation instructions and further information are in the product’s Installation guides and technical specifications.

      Hardware Configuration: New Design

      Hardware Configuration has been completely redesigned, to allow for the new UniStream 5 series.

      Note that the controller you select modifies the option that UniLogic presents for I/O and COM modules, and shows only the options that are relevant for your selected controller.



      Additional Features and Improvements

      SD Card Management

      Via SD Management, you can limit the number of files; when the limit you define for a specific file type is exceeded, the controller will automatically delete 1/8 of the oldest files for that feature.

      UAC: Management Level

      Management Level enables you to set the ability of group members to edit the properties of other members. Members of the New Super Group level can edit any and all properties of Users or Groups in UniApps, including the properties of other Super Group members. This can be very helpful in cases where Admin passwords have been forgotten.

      Data Table Values

      Three new features have been added:

      ·         Read/Write Data Tables values To/From PLC
      Link to your PLC, and then click the appropriate button.

      ·         Export/Import range
      Drag your cursor across the desired cells to highlight them, and then click the appropriate button.

      ·         Copy to Clipboard
      You can now highlight a range of cell, and use Ctrl +C to copy the values to Windows Clipboard.

      Note that as of this version, you must double-click a cell in order to view the values. This was done to enable you to click once in a cell, and drag your mouse to highlight a range.


      Passwords: Import Export via UniApps

      When you import or export an application via System>User App Upgrade>, you can now include the VNC passwords.

      VNC Password

      You can now choose whether or not to enable a VNC server Password.

    3. VisiLogic:9.8.64 - Link to mobile app, Ladder: 2x the Space!   (10,454 visits to this link)

      This major release introduces a number of new features that will boost your productivity, such as wide Ladder nets and dynamic I/O configurations.

      In addition, when you install this version and open it for the first time, a pop-up will allow you to access app store links for Unitronics’ Remote Operator for Mobile app.

      The following list is a partial list - for the complete rundown, read the version changes at"https://unitronicsplc.com/software-visilogic/

      New Features

      Remote Operator for Mobile

       The Help menu now offers a link that will access the App store. In addition, the Help topic Remote Operator via Mobile App now contains QR codes that you can scan with your mobile to get the app.

      2X the Space

      VisiLogic Ladder nets are now wide, and reach completely across your PC screen - no empty areas.  This gives you twice the editing space.

      Switching I/O Configurations

      Once you have added I/O Expansion Modules to your project, you can create variations called 'IO Module Configurations'.

      Configurations are hardware profiles that enable a controller to run the application if it has a physical I/O configuration that is different from the full I/O Configuration in the project. Each profile that you create has an index number.

      You determine which configuration is active by storing a value in SI 205. The application will run according to the selected Config without error.

      To enable your program logic to run correctly when switching configurations, you must map the digital inputs and outputs to MBs, and use these MBs as program conditions instead of Input and Output operands. Since analog I/Os are linked to operands, they do not require any special handling.

      Let me tell you--this is going to be GREAT!!!!
      We are proud to introduce an addition to the UniStream family that is going to be a favorite among those of you who enjoy the compactness, the no-hassle approach of the All-in-One Vision series.
      UniStream 5" is a PLC+HMI+I/Os , with the impressive UniStream user panel built-in, available in a number of I/O configurations, that you program in UniLogic.
      Below is the official release document--you can access specs, etc, over here.
      UniStream® 5”: PLC+HMI+I/Os
      Compact. Contemporary. Connected

      Unitronics’ newly-released UniStream® 5"- a multi-function programmable logic controller in a superbly compact hardware profile: PLC+HMI+I/O built into a single unit.
      All-in-One, compact PLC + HMI with built-in I/Os fills a niche in the programmable controller market—serving OEMs and system integrator who need space-saving controllers that deliver the functionality to control complex machines, while creating a competitive advantage via a color-touch HMI panel.
      This All-in-One controller is available in two series: UniStream 5" and UniStream 5" Pro. Both series support SNMP, VNC, FTP, SMS, email, and communications via GSM/GPRS modem.
      The Pro version also offers a built-in Webserver, audio jack, and video support, as well as SQL, a plus for system integrators and OEMs facing Industry 4.0.
      The Hardware
      UniStream 5", with its resistive color touch-screen reduces space and wiring requirements, and eliminates the need to set up Panel-PLC communication.
      Built-in I/O configurations vary according to model, offering digital, analog, high-speed and temperature I/Os. Users can expand the configuration up to 2,048 I/O points.
      Built-in COM ports include Ethernet, 1 USB host and 1 Mini-B USB device ports; additional add-on ports for serial and CANbus are available.
      Powerful Programming
      The rich feature range of UniStream includes auto-tuned PID, data logging, data tables and Recipes, data sampling displayed via built-in Trends and Gauges, Alarms, multi-level passwords, and plug & play communications for CANopen, CAN Layer2, MODBUS, EtherNet/IP, and more.
      A Re-Use paradigm enables the programmer to build Ladder and C functions, design HMI screens, and create Web pages in multiple languages including Asian languages—then save it all in a Library to reuse in other projects.
      Another benefit to the bottom line for the OEM and system integrators is Unitronics standard policy of customer care—no hidden costs or tiers. All software, utilities, and support—including membership in Unitronics’ Community Forum—are provided at no additional charge
