    1. UniLogic 2021-- UniCloud IIoT Cloud Platform, EtherCAT & more!   (282,473 visits to this link)

      UniLogic’ first 2021 release supports UniCloud, Unitronics complete, no-code IIoT Cloud Platform specifically designed for the OEM and Machine Builder. End-to-end, scalable and secure, UniCloud enables you to easily build customized Dashboards and use them to harvest, analyze, and leverage data to boost efficiency, trouble-shoot problems, and implement preventative maintenance—reducing your management overhead and leaving you time to grow your business.
      You do not need programming or cloud development skills in order to commission and deploy UniCloud—you can benefit from IIoT services, increase your revenues, and save on costs without relying on programmers and cloud professional staff.

      This release also introduces UniStream 'Cloud' controllers.  UniStream 'Cloud' controllers are an industry first: a PLC with built-in, no-cost cloud services. Each UniStream Cloud PLC is supplied with a pre-paid 5-year Start-up Subscription plan-there is no monthly subscription fee.

      UniCloud is also supported by Vision Enhanced, Samba, and will soon be supported by Jazz. While UniStream connects directly to UniCloud, note that other controllers connect via Unitronics secure routers.

      To learn more, and take advantage of our free trial offer, click here: https://unitronics.cloud/product/

      This release also supports EtherCAT, the industrial fieldbus protocol that drives powerfully precise processes in factories across the globe, via our new EtherCAT Master module. The new module enables you to integrate:

      ·         Unitronics EtherCAT Servo Drives
      When you use a Unitronics drive, EtherCAT data exchange is transparent. You can implement motion using UniLogic's Motion function blocks. A single UniStream can support up to 8 drives. Plus, you can easily adapt any Motion application based on CANopen to EtherCAT simply by making a few changes in Hardware Configuration.

      ·         Unitronics URB EtherCAT adapter
      Via an EtherCAT URB adapter, you can communicate with Unitronics URB Ethernet-based I/O modules

      ·         Third-party EtherCAT slave devices
      You can import a device's definition file, and exchange data via Ladder using SDO requests.

      A single UniStream can support one EtherCAT master module, which can support a total of 32 EtherCAT nodes. This includes EtherCAT Servo drives, Remote URB adapters, and third-party EtherCAT devices.

      *EtherCAT is currently supported by USC-B5 and USC-B10 only.

    2. VisiLogic: 9.9.00 - Protect Your Vision and Samba Systems with New Security Enhancements   (259,081 visits to this link)

      VisiLogic 9.9.00 focuses on enhancing and strengthening the protection of your automation systems.
      It requires you to change default passwords and implement complex passwords and comprises new features to protect Vision and Samba controllers. These features include mandatory password protection for PCOM communications via Ethernet, a method enabling you to block remote access actions initiated via PCOM, and a way to change the Information Mode default password via Ladder.   

      Unitronics strongly recommends that users with existing applications comprising Vision and Samba controllers that are connected to the internet, update to the current VisiLogic and firmware version, as well as to updated versions of Unitronics’ compatible utilities.

      In addition to securing Device Level security by using the features included in this new VisiLogic version, implementing effective system security requires a layered approach.

      While upgrading to this version enhances device security, network protection is essential as your first line of defense.

      It is highly important to make sure that any internet connection will be done using firewalls to restrict unwanted access and that there are no port forwarding settings exposing automation equipment directly to the public network.

      Upgrade Now for Enhanced Security

      We highly recommend updating to VisiLogic 9.9.00 to benefit from the latest security enhancements and ensure the protection of your critical industrial systems.

      The new version is available on our site: https://www.unitronicsplc.com/software-visilogic-for-programmable-controllers/

      * For UniCloud customers: please contact us for specific guidance.

      Hi people!
      Our newest product was developed in answer to customers who needed UniStream performance--but who do not require an integrated HMI panel.
      >drum roll<
      Meet the UniStream PLC  
      This unique PLC,  unlike other UniStream controllers, does not have an integrated HMI panel--however,  it supports HMI applications just like any other UniStream.
      The secret is Virtual HMI. This means that you can mount the controller on a DIN rail in a cabinet, and access it from:
      any mobile device that supports VNC the new UniStream Display (USL) any UniStream Modular HMI panel (USP) any UniStream Built-in (on the panels integral to the device) The UniStream PLC is a line of PLCs with built-in I/Os that may be mounted on a DIN-rail. Unlike other UniStream Controllers, does not include a built-in HMI screen.
      This PLC is appropriate for applications that need UniStream power and functionality, but that either do not require an HMI application, or that require a distributed HMI.
      All UniStream PLCs support Virtual HMI--they can display HMI screens which you design in UniLogic in exactly the same way as for any other UniStream controller. You can display the HMI screens on:
      UniStream Displays (USL), included in this release. UniStream Displays are a series of color touch-screens that support VNC.
      UniStream Modular HMI panels (USP)
      UniStream Built-in (on the panels integral to the device)
      Any device screen that supports VNC

      The series is available in three versions: Pro, Standard, and Basic.
      When you select your UniStream model in Hardware Configuration, only relevant options are available in UniLogic.

      ----------------------------------From our official press release:
      The UniStream PLC is based on proven, award-winning UniStream hardware and UniLogic software that enhances your ability to implement all of the control tasks required by your machine or process application.
      A multi-function controller that matches a vast range of application requirements, the UniStream PLC provides users with advanced communication support, including Industry 4.0, and introduces a unique concept in Virtual HMIs.
      Virtual HMI – A New Approach to Automation
      UniStream PLC combines two technologies in one product:
      Virtual HMI– As an Industry first, the PLC stores and runs the program logic as well as the HMI user application within the PLC itself. This brings you a unique advantage: you can view and operate your machine, or access your process via any mobile phone, PC, or remote display device. Controller Hardware – The powerful controller has built-in I/Os that can be expanded to more than 2,000 I/Os, including digital, analog, high-speed and temperature, as well as communication modules supporting Modbus, Ethernet/IP, MQTT, SQL, SNMP, and more.   Along with the UniStream PLC, Unitronics has also released a line of compatible displays, offering customers a full package for varied PLC and HMI requirements.
      Award-winning Programming Software
      UniStream PLC is backed by UniLogic® all-in-one programming software, which cuts programming time up to 50%, and includes Built-in Trends and Gauges, auto-tuned PID, data sampling, complex data tools, Recipes and more.
      UniLogic offers OEMs and System Integrators a faster and easier programming solution as all tasks can be programmed using the same software environment. Users can build the PLC application, design HMI screens, create web pages in multiple languages, and save it all in a library to reuse in other projects.
      The best of two worlds: Robust PLC Hardware with Virtual HMI
      With its robust hardware and extremely efficient time-saving programming software, the new controller benefits users in multiple ways, simplifying and speeding projects, while offering outstanding configuration versatility.
      “Unitronics is well-known for outstanding innovation, and with our new UniStream PLC, we’ve done it again,” says Boaz Karmy, VP Sales and Marketing, at Unitronics. “Richly featured and powerful, yet compactly designed, the UniStream PLC raises the bar by providing unique Virtual HMI features and versatile hardware configuration, using the same programming environment.” –

      One of our community members, @YINGD suggested that we open up a forum section dedicated to HMI Design, and our long-time MVP @Flex727seconded the suggestion --so we did!
      Here is the main section, with sections for UniLogic and VisiLogic:

      I hope that this will prove helpful to our community--thanks for the suggestion!
