How to Log Modbus Data to Microsoft Access and Excel
What you'll learn
- Have an appreciation for the basic Structured Query Language commands
- Build a Human Machine Interface to capture a Modbus data point
- Configure a Human Machine Interface to log data to a Microsoft Access database
- Configure a Human Machine Interface to log data to a Microsoft Excel file
- Have an introductory appreciation for HMI scripting
- Basic working knowledge of the Modbus RTU protocol.
- Familiarity with the installation of software applications on the Windows OS platform
- Familiarity with Microsoft Access and Excel
Archival of process control data is paramount to tracking of process performance and troubleshooting of issues with the process plant. Modbus is used heavily to acquire process data via the use of Human Machine Interfaces (HMIs). HMI's typically have the ability to not only read real-time data but also to archive that data for further analysis. A frequent drawback of HMIs is that archived data is usually stored in a proprietary format, which can make porting data to other system for further analysis problematic.
This course details the use of the Winlog Lite HMI in archiving process data directly to a Microsoft Access database as well as a Microsoft Excel workbook. By being able to do this type of archival, porting of data becomes much easier and faster.
The course uses a Modbus slave simulator from which the HMI acquires a single data point which is deemed a line pressure. The HMI is then configured to have this data point archived every 10 seconds a Microsoft Access database as well as a Microsoft Excel file. Structured Query Language (SQL) is introduced to the student as well as an example of HMI scripting.
The course is very practical and the student can perform all tasks that are shown in the videos. In fact, throughout the course, students are strongly encouraged to do all that is show in the videos for maximum learning effect.
Who this course is for:
- Electrical Engineers
- Electrical Technicians
- Electrical Tech or Engineering Students
- Process Control Technicians and Engineers
- Process Automation Engineers
I have been working in the fields of Software Development, Software Systems Integration and Process Automation since 1996. In 2003, I stepped out on my own and started working for myself providing software development and systems integration services to small and medium businesses.
I am also associated with a great company called Mora Systems Limited that under the leadership of it's Managing Director has produced innovative and outstanding products and services in the fields of GIS and Cellular based SCADA.
Teaching has always been a passion for me. I have taught at the tertiary level for many years on the subjects of programming, control systems as well as systems integration. In the last few years I found myself incorporating more and more videos into the curriculum with amazing results.
When I heard of uDemy I just could not help but sign up. With teaching in a classroom, you can reach only so many students, but with uDemy you can reach the world! I plan to publish and promote as many courses as I possibly can on the uDemy platform.
