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 an unlimited number of 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.

Clicking the link below will take you to the login portal:

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 an email and password, enter the email “[email protected]” and the password “12345678”.

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.

Please note that remote access is not compatible with Internet Explorer.

Shown below are some sample screen shots.

  • Log into the portal using email “[email protected]” and password “12345678”. Please note that remote access is not compatible with Internet Explorer.
  • Select either the Modem or Ethernet demo analyser.
  • You will see a page with measurands e.g. pH, chlorine. This is called the ‘Dashboard’.
  • Let’s suppose that the chlorine reading is 0.46 mg/l and we want the chlorine to always be lower than 0.45 mg/l (we will only set up the high level alarm in this tutorial).
  • Now click on the Free Chlorine sensor tile and then select Alarm 1 or Alarm 2. From this menu, you can set up the alarm.
  • Press ‘Edit’ and enter the settings below, then press ‘Save’:
    • Enabled: ticked
    • Set Value: 0.45
    • Reset Value: 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.
  • Press ‘Menu’ (near the top of the page) and then select the Modem tile.
  • Select ‘SMS Alerts’ and enter the settings below, then press ‘Save’:
    • Enabled: ticked
  • Select ‘Phone Book’, then press ‘Edit’.
  • Now enter your number using the following format; + Country Code – Phone Number (e.g. +4455512345678) and press ‘Save’.
  • Shortly you will receive a message telling you that there is an alarm.
  • To acknowledge the alarm, send a text back to the analyser with the message ‘OK’.
  • Once the alarm is acknowledged, press ‘Menu’ and then ‘Refresh’ on the Dashboard.
  • The Analyser tile should now be yellow, indicating that the alarm has been acknowledged.
  • After you have received the message, please remember to delete your number (Modem > Phone Book > Edit > Delete Number > Save) and de-activate the alarm (Free Chlorine > Alarm 1 (or Alarm 2) > Enabled: untick > Save).
The steps below will show you how to download data and status logs:

  • Log into the portal using email “[email protected]” and password “12345678”. Please note that remote access is not compatible with Internet Explorer.
  • Select either the Modem or Ethernet demo analyser.
  • Select ‘Data’ on the left. You can change the data range in the top left corner.
  • The settings below the graph allow you to change what information is displayed on the graph, and how it is displayed.
  • Try enabling or disabling a few parameters, and edit a parameters scale. The graph will update in real-time.
  • To download an image of the graph, simply press ‘Download Image’. If you wish to download the data, press ‘Download CSV’.
  • To download the status logs, select ‘Logs’ on the left then press ‘Download CSV’. The data range can be changed at the top left of the page.
The steps below will show you how to change the run mode, manual value, PID set-point and gain values:

  • Log into the portal using email “[email protected]” and password “12345678”. Please note that remote access is not compatible with Internet Explorer.
  • Select either the Modem or Ethernet demo analyser.
  • Download the latest settings by pressing ‘Refresh’.
  • Select the PID Control (Cl) tile.
  • To change the run mode, select ‘Control Setup’ then click ‘Edit’. From here you can change the mode to ‘Off/Manual/Automatic/Semi Automatic’. When selected, press ‘Save’ to close the setting window.
  • To change the manual value, select ‘Output Setup: Primary’ then click ‘Edit’. Enter your new manual value and press ‘Save’.
  • To change the PID set-point, select ‘Setup: Setpoint’ then click ‘Edit’. Enter your new setpoint and press ‘Save’.
  • To change PID gain values, select ‘Setup: PID Tuning’ then click ‘Edit’. Enter your new values and press ‘Save’.

You probably know that Process Instruments offers a cloud based remote access service for our CRIUS® analyzer, but did you know that…

…nearly everything you can do in front of the analyzer you can do remotely?
…we have been working closely with our customers to bring you an even better service?

Major Improvements to Remote Access for 2018

Remote Access DashboardUser interface – A whole new layout and interface now mimics the analyzer better, making the data and other features much easier to find.

User control – Each user has their own customizable access rights for what they can view and change on the analyzers. This is set by the ‘parent’ user.

Speed – The service now runs around 50 times faster than its predecessor, allowing users to connect and download the current sensor values and settings in under 30 seconds (test performed on CoagSense coagulation controller with 27 different devices such as sensors!).

Reduced data costs – By making the connection between the server and analyzer more efficient, Pi has reduced the amount of data required for nearly all tasks thereby significantly reducing costs.

Customer branding – On request, Pi can brand the remote access theme to promote a customer’s brand.

Remote Access GraphsData analysis – The graphical interface has been designed to look cleaner and easier to read. The number of data points that can be downloaded or viewed on a single graph has now been increased from 5000 data points to every single data point stored on the server, allowing a user to download months’ worth of data with a single click.

Error handling – If the connection between the analyzer and server fails, the server will now display helpful messages which will explain why. To do this, the user selects the ‘Test Connection’ tab in the corner of the dashboard, which will start a full scan between the analyzer and the server. Once the scan is complete the server will display a message if there are any issues affecting the connection.

Password reset – If a password has been lost or forgotten, a user can enter their email address into the password reset function which will then email a list of instructions on how to reset it.

Data limit – Users can now limit how much data each analyzer can use per day, meaning no more unexpected data costs.

So what can Remote Access do for you?

Remote Access Dashboard - CoagSenseThe remote access service has always been designed to save you time and money by allowing you access to the analyzer and its data from anywhere in the world. Now remote access can assist as a tool in doing a lot more:-

  • Remotely checking and changing settings for customers who may not be confident in doing so or who may not have access to the analyzer.
  • Allowing Pi’s service team to temporarily remotely connect to the analyzer if customers have an issue and are unsure about how to solve it.
  • Automatically sending daily/weekly reports of data logs and/or status logs to users from the server (no mobile data costs from the analyzer).
  • Easily view when maintenance is required or due on analyzers, allowing users to efficiently plan which sites to visit and when.
  • Know when alarms activate on the unit within seconds by enabling text and/or email alerts direct from the analyzer.
  • Tune control values to optimize dosing without the need to visit the site.
  • Analyze stored data to investigate incidents, explain issues or validate the process.
But what about security?

When the analyzer and remote access server communicate, Pi uses a ‘Pre-Shared Key’. This creates a secure connection between the server and analyzer. The key acts as a password and without it the analyzer will not respond. The key is randomly generated in every analyzer making it unique to each, and if required the key can be re-generated from the analyzer. The analyzer can also be connected directly to a Virtual Private Network (VPN) which blocks unwanted traffic and connections automatically and will only transfer information between the analyzer and server.

How does user access work?

Each user has their own username and password. This means that what they see and what they can do can be customized so only authorized users can make changes.

How are the analyzers and customers managed?

If a user creates a group, then they become that group’s ‘parent’. The ‘parent’ of a group creates the analyzers and users for that group. If a user is a ‘parent’ to more than one group, they will also have the ability to create users that can access multiple groups from a single user account.
