Did you know...? iOS & Android: Remote Operator for Vision and Samba

Cara Bereck Levy



Did you know that Unitronics Remote Operator, the mobile app for the Vision™ and Samba™ series, is available--at no cost--from Apple’s App and Google Play stores?
Remote Operator application enables you to remotely access your Unitronics controllers using your smartphone and tablet. Via the app, you can view and operate the controller’s HMI —as if you are physically touching the controller. Using Remote Operator you monitor automation processes, press keys and touch HMI objects, change parameter values, view Alarms and process value Trends. You can define and access multiple controllers from a single mobile device.


We invite you to download the app, give a whirl--here's a link to our handy Quickstart guide to help you hit the ground running:

Hi I just installed the app on my iPhone 6, latest ios. 


I added 3 Vision PLC's 230 and all of them have the green hand and are online (I can get the PLC information, and the connection check is successful)

However when I try to connect to them I have the error "Connection Error - connection to PLC failed)


Am I doing something wrong?

In the version for android, which I tested, in the LAN until it works well, but in the WAN it is extremely slow when changing the screen, it blocks the application or, what is worse, it gives red screen in the PLC (Vision 570), what makes it a Extremely dangerous application. The Pc version is also extremely slow on the WAN (I've been using it for over 9 years and there's never been an improvement in the emote operator with Internet connection).

As for the application long time, in the first connection of the application it is downloading the images, depending on the number of element on the HMI will determine  the connection delay time.

Can you please end me your project to Support@unitronics.com  so i could try to simulate the red screen.

If you could provide a scenario that i could simulate this red screen?

Thanks Guy Sela, First, the V570 red screen  only happens under RO use, on Ipad happens 3 times and android app more times only on LAN network at normal use.

The delay on images files uploading are not the problem, we use the apps for RO at the beginning and ever are very slow. The clients consider the RO on PC slow too but they get used. I imagine it is some limitation of the PLC or the ethernet card when we access from the WAN.

I try to made a movie from the RO on WAN in 4G mobile and other fast network. Will send to the support, can I address the mail direct to you?

Buy recently a JZ20-T40 with Ethernet add-on card MJ20-ET1. Remote Operator works on PC but on android and iOS only communicates (SB24  on state) and shows "connection to PLC failed!". Does anyone know if there is any forecast to work on mobile phones or am I doing something wrong? I still want to send a video of the operation of the RO in external networks (WAN), but I do not know who to send, just sending to the support, it is usually necessary to explain the same thing over and over again.

When click on Unitronics' Remote operator at Apple or Google, expand "READ MORE" and scroll down.

Look for requirements and supported controllers models.

Jazz is not in this list, so it is not supported.

Supported most used models of PLCs, where it is required.

If you have requirement to support Jazz PLC, send it to support@unitronics.com.

Add project potential and your requirement will be evaluated.

By the way, PC Remote Access and PC Remote Operator supports Jazz PLCs.
