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”

  • 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
