Schneider Electric Powermeter with Modbus RS485
Water: simple pulse meter
Natural Gas: measuring hours of NG boiler
Temperature: Sensor
Microsoft Azure (cloud)
Matrikon UA Proxy
Matrikon OPC Client for ODBC
MySQL database with calculations
Customer Portal
Final destination of data

5. Data Collection :Modbus Challenges
No Timestamps Available
Difficult to Interpret
Not Secure
Simple Data
Many Variations of the Protocol

6. Alternatives 1) Industrial PC 2) Media Convertor (Modbus to Ethernet)
+ Secure
- Cost
-Maintenance (Windows Patches etc)
2) Media Convertor (Modbus to Ethernet)
+ Cost
- Security
- May need more than one per location

7. Solution: UA Modbus Gateway
Hardware Gateway
Connections to Modbus Devices
Secure down to device layer
Microsoft Windows not required
Uses TCP and Serial communications
Remote Locations
Space limitations
Environmental factors
Power limitation (solar)
Configure remotely

8. UA Modbus Gateway Benefits
Replace PC’s with embedded devices, no more maintaining Windows
Reduced Cost of Ownership
Can be installed in existing hardware cabinets without needing to install new PC
Low Space Profile
Enables secure data down to the device level
Enables Secure Data Transfer
No need to get IT to purchase /maintain
Engineering can maintain ownership
No Need for IT
PLC data is available to view on tablets and other mobile devices because of the UA capabilities.
View Data on Mobile Devices

9. Factors Driving Value right down to the device SECURE DATA
No additional hardware required.
No Windows patches
REMOTE CONFIGURATION and maintenance through simple utilities
able run in remote facilities with solar panels.
LOW POWER USAGE
(the size of 2 decks of cards)
SMALL PROFILE SIZE
RESTART REMOTELY

Matrikon Modbus UA Gateway Device Configuration

19. Cloud-Based Utilities Monitoring

20. Cloud-Based Utilities Monitoring
Configuration of Matrikon Products
Matrikon Modbus UA Gateway Device
Configuration console program
3 files required:
ports.csv, defines communication with device(s), ex.,
COM1,S,RS485_2WIRE E 1 NONE,MODBUS,RTU
COM2,S,RS485_2WIRE N 1 NONE,MODBUS,RTU

21. Cloud-Based Utilities Monitoring
Configuration of Matrikon Products
Matrikon Modbus UA Gateway Device
tags.csv, defines the values read from device(s) into tags, and
User permissions, Read, Write, View Access
ex., COM1,COM1.AI.VOLTAGE_A-B,1,3,1054,,ALL,ALL,ALL
acl.csv, defines users / passwords with access to the device,
Username, token type (P)assword or (C)ertificate (only P is supported), Plaintext token i.e. password,
ex., operator,P,operator,
Matrikon UA Proxy
Connection: opc.tcp://XXX.XXX.XXX.XXX:4840
User permissions:
ALL – all users, including anonymous.
ANON – The anonymous user.
ALL_NON_ANON – all users, not including anonymous users.
The administrative user with the initial configuration password always has read/write and view access to all tags. A blank entry in one of the permissions fields indicates no access of that type except by the administrative user.
Plaintext token:
For password tokens, this is the password of the user, in plain text. When read by the server, the password will be hashed, and the file on the device will be re-written to store the hash.

22. Cloud-Based Utilities Monitoring
Challenges to solve
Connectivity with devices
Modbus RS485
Modbus Register type + access
Connectivity with Microsoft Azure Machine (cloud)
Municipality-enabled Internet access (ADSL / VDSL)
GSM communication
Static IP required from Provider
Port Forwarding (ports )
Firewall Ports open from Municipality / Provider

23. Cloud-Based Utilities Monitoring
Challenges to solve
Security
Internet-based access is always a risk
Minimize risk by accessing only 2 ports: 4840 and 22
Port 4840: for OPC UA data access
Port 22: for Matrikon UA Gateway device initial configuration
Connectivity from MySQL to customer database
Suitable SQL scripts
Calculations

24. Cloud-Based Utilities Monitoring
Results / Benefits
Fast implementation
Data available on line for evaluation
Possibility for calculations of expected benefits from utilities consumption
Project is ongoing, Customer still needs to identify areas of improvements to realize benefits
Lessons Learned
Cloud technology usage is not difficult and is Scalable
Matrikon software can work on the cloud
Access to cloud server from anywhere
Zero maintenance requirements
