Goodday. Ben Here.
00:03
In this video I’m going to show you how you can quickly and easily use groov to view and control your ModbusTCP devices
00:10
from your mobile device or PC web browser.
00:13
groov is a zero-programming, web-based way to build and view scaleable operator interfaces
00:17
to monitor and control systems and equipment from any modern mobile device.
00:25
groov comes pre-installed on an industrially hardened appliance that has no moving parts,
00:30
or a software-only version can be installed on a Windows-based computer.
00:37
Either way, the development environment and the projects created all run within a modern web browser.
00:43
For your mobile device you can use the built in web browser, or better still, use the free groov view app for either Android or iOS.
00:53
groov comes with various system communication drivers built in, including OPC-UA, Opto 22 Snap-PAC and Modbus/TCP.
01:04
With  Modbus, groov is a TCP Master and can communicate natively with Modbus/TCP slave devices
01:12
like level sensors, variable speed drives, power meters, or industrial controllers.
01:17
Because groov talks directly to the Modbus/TCP slave device over standard Ethernet networks,
01:24
there’s no intermediary servers or protocol converters required.
01:28
This greatly simplifies hardware planning, network layout and makes device setup and configuration straightforward.
01:37
So, here’s how to view and control your ModbusTCP slave device using groov:
01:44
Ive already got an application that shows the mains voltage from the PCube power meter
01:49
so lets now set up a digital output from groov on the Advantec to switch the studio lights on and off
01:57
First, here in groov Build, we select the type of device we are going to connect to
02:02
In this case its directly to the Modbus device.
02:05
Next, give it a name, its IP address and its Modbus slave ID.
02:13
Now we can configure the tag, give it a name, select the data type,
02:18
since its a digital point, we can accept the default boolean.
02:22
Use the Tag Address Builder to construct the coil address, hit save and we are ready to connect the tag to our gadgets.
02:29
Lets add a button, to control the lights. While we are here, lets also add the digital state to the trend
02:45
Too easy!
02:47
Now we just save our project, and view my new page in my web browser.
02:53
Now I want to see my changes on my mobile device. I’ll open groov View for Android on my smart phone and check out my updated page.
03:02
Let’s test out our light switch.
03:05
groov is writing directly to the modbus coil register of the Advantac controller.
03:13
In many cases, groov can be added into an existing system without having to make any changes to the current setup just like I did in this demo.
03:22
This means it’s a simple process to add a mobile interface to existing installations.  
03:29
Be they a machine or a remote site, groov can add mobile device visibility of the process in just a few minutes.
03:38
You can check out groov in action on your mobile or PC by visting https://demo.groov.com and log in with a username of ‘trial’ and a password of ‘opto22’.
03:52
You can also download a free trial of groov Server for Windows from groov.com, and test drive the full-featured version of groov for 2 hours at a time.
04:02
There’s also a bunch of tutorials and workshop videos on the website, Check it out!

Till next time, Cheers Mate.
