The Process Instruments CRIUS® controller can provide as an option, remote access via LAN or GPRS modem.

This capability is unique in that it:
Remote Access page

  • provides two way communications allowing not just the downloading of data but the uploading of new settings, setpoints, PID controls, etc.
  • provide peer to peer communication so the controller talks directly to the internet, there is no web site in the middle to have to log on to.
  • email alarms and daily emails can be sent to up to 5 email addresses. The daily email has the previous 24 hours data attached, so you need never download data again, it just arrives in your inbox.

In order for you to try the remote access capabilities of the CRIUS® controller, Pi has set up an instrument in our facility in Burnley, Lancashire, UK. This can be set up as various analyzers including a Residual Chlorine Analyzer, a Swimming Pool Controller or pH Analyzer depending on what else it is being used for. If you wish to see a particular configuration then please contact one of our sales people who will arrange for the unit to be reconfigured.

From this page you can access it via this link:

Note that these analyzers are being accessed via the phone network and the signal strength may vary. Also it is only possible for one person to connect to the analyzer at one time, so if you are having problems wait a while before trying again as someone else might be using the unit.

After you have connected you will be prompted for a username and password, enter the username “public” (in lowercase) and the password “123456”

Best results will be achieved if you only click on one button at a time and wait for the page to finish downloading before clicking a button. Please feel free to navigate around the instrument (don’t forget that this is the actual instrument that you are connected to, not a web page simulation).

The unit is periodically reset so any data on it will not be kept, however it is advisable to remove any phone numbers or email addresses that you might enter during your testing when you have finished.

Shown below are some sample screen shots.

Remote Access pageRemote Access pageRemote Access page

  • Log on this page and use username “public” and password “123456”
  • From the main screen go on Status (top-left corner)
  • You will see a page with measurands e.g. pH, chlorine
  • Let’s suppose that the chlorine reading is 0.46 mg/l and we want the chlorine to be always lower than 0.45 mg/l (we will set up only the high level alarm in this tutorial)
  • Now click on Setup (top menu) and then Alarms (left menu) and finally Free Chlorine Sensor. From that page you can set up the Alarms
  • On the first panel “Alarm 1” select:
    • Enabled : ON
    • Set: 0.45
    • Reset: 0.40
  • In this way when the chlorine reading rises through 0.45 the system will go into alarm and it will come out of alarm when it falls through 0.40.
  • On the left menu go to Comms then SMS Alerts and chose:
    • Setup → Enabled
    • Phonebook → Insert your number here in the format + Country Code – Phone Number (e.g. +4455512345678)
  • Press Submit
  • Shortly you will receive a message that will tell you that there’s an alarm
  • To acknowledge please send a text back to the analyzer with the text “OK”. In this way the analyzer knows that you know about the alarm and you are going to do something.
  • After you have received the message please remember to delete your number and de-activate the alarm.
In order to download some data from the analyzer you have to:

  • Log on this page and use username “public” and password “123456”
  • From the top menu chose Logs
  • If you want to download the System Logs then just click the download button at the bottom of the page
  • Otherwise if you want to download datalogs for a specific parameter chose Data Logs from the left menu
  • Then select the parameter and click Download
  • You get all the Datalogs in CSV format
In order to set up the PID you have to:

  • Log on this page and use username “public” and password “123456”
  • From the top menu chose Configuration
  • On the left menu chose Cl Control
  • From the Control Details panel select Mode: Automatic
  • You will see at this point three new panels where you can setup all the values for PID control

You probably know that water monitoring controllers can be connected to site SCADA systems, but…

… did you know that with Pi Remote Access you can change settings on the controller from your home or office without setting a foot out the door?
… did you know that you can still access the controller, even if it’s in an area with no network signal?

What is Remote Access?

Pi Remote Access is a cloud-based server designed to save you time and money. Ever wished there was a more convenient way to access your water monitoring controller? Tired of wasting time driving to sites miles away just to change settings? Welcome to our Remote Access service…

Remote Access GraphsPi’s Remote Access server draws information from the controller on site and displays current device values and historical graphs. The server is designed to be as user friendly as possible. The graphs can be adapted and manipulated, giving you the freedom to display information however you want.

We have designed the Remote Access to have a two way interface. This means that not only can you view nearly every setting on the server that can be seen on the analyzer itself, but you can also alter these settings too. Logging on to our Remote Access server really is like being stood in front of the controller itself!

Remote Access DevicesThe best thing about our Remote Access service is it’s free! There is just the initial cost of equipment required to access the server, but no ongoing service cost after that.

Here at Pi, we know from experience that one size does not fit all. Each site has its own connectivity issues and access restrictions. That is why we have designed our Remote Access to be accessible through a variety of different options, which are outlined below. If you are unsure about anything, don’t hesitate to get in touch, we will be happy to help.

If Your Facility has a LAN (Local Area Network)

In this case, the controller can be connected to the LAN on site with an ethernet cable. We provide you with your own Remote Access account which enables you to use our server. Depending on the LAN settings, a VPN (Virtual Private Network) and/or dynamic DNS (Domain Name Server) may be necessary for the controller to connect to our Remote Access server.

Is your LAN access restricted, or ever not connected to the internet?! No problem! We have other options for you…

LAN Access Restricted or no LAN at all

If LAN access is restricted or there is no LAN on site, we can provide a GPRS modem with a SIM card instead. This will provide a fixed IP address, enabling you to use the Remote Access server. This is available in nearly every country around the world. The SIM card works very much like the one in your mobile phone, it requires sufficient network signal for the Remote Access to work effectively. There are charges for data usage paid to your network provider, but these charges tend to be very low due to the small size of the data required to use the Remote Access.

No network signal?! No problem! We have a Remote Access solution for that too…

Remote Access Hardware AdapterLAN Access Restricted and no Network Signal

If LAN access is restricted and there is no GPRS network signal either, an external server box is the solution. This is a common option used in hospitals, as access to their network servers is often restricted. The external server box is attached to the controller via an ethernet cable and generates a WiFi network. Accessing this WiFi network through your computer will enable you to connect to our Remote Access server.

Even with restricted LAN access, if the site has a designated VPN, you will be able to use this to access the analyzer and connect to the server from your home or office, without needing to go to site.
