The GRIDview Asia client is loaded on a Red Lion/Sixnet cellular router or IPm controller before being installed. When the target device is connected to the Internet, it automatically registers itself with our server and requests a configuration. It sends periodic status reports indicating system health.
The client initiates all communication to the server. The server never has to "find" the device; the device checks in periodically to download any changes to configuration. Variables to monitor, control programs and software updates are all downloaded at the interval you specify. Have a cellular connection with a low bandwidth limit? No problem. You can turn checkins down to as low as once every 24 hours. Troubleshooting over an Ethernet connection? Get updates as fast as every 5 seconds.
At the core of most applications we host are data points to be logged. We're not just monitoring the equipment, we're monitoring a process. Chances are you've got at least a few analog or discrete points you want to monitor. We can poll several hundred points and record changes as fast as every 100 milliseconds. We give you fine grained control so you can see the shape of your data changes. Naturally we also let you write to outputs. Setpoints and state changes are transmitted on the schedule you select.
A GRIDview Asia application consists of control programs running on the RTU and their configurations (loadable through our Files page), variable tags, alarms and any special templates you need. You can subscribe to instant messages or daily/weekly reports. Our site is the conduit for operating your remote assets.
At an application level, the site controls access by group and privilege level. Admins can add and delete devices, load files, set communication parameters and manage variable tag and alarm lists. Writers get to write to setpoints and change discrete states. Subscribers can sign up for reports, including instant message notifications.
Wherever possible, communication is encrypted. This includes enforcing TLS in the field device client session, the user session and between the web server and database server. We use encryption to protect our outgoing email traffic, too. Your password is kept in a hashed format.
We take security seriously and we view it as an ongoing process. We welcome suggestions for how to improve.

It is easy to get started with one or two field devices and a built-in template. You only pay for what you use: we use a subscription and declining balance system to track the number of active devices you have in a given month and charge your accordingly.
As your device network increases in size, you may wish to add custom templates or even have us build apps to run remotely or on the server. If you can imagine it, we can probably find a way to build it on our infrastructure—much faster than you would be able to build it from scratch.
Once your device count exceeds a hundred devices or so, we may want to move your project to its own server. You get to pick the domain. Contact us for details and a quote.
If you have very particular needs for a special project, the GRIDview Asia platform will run on a standalone server at your location.
