Now You Can Have Data Logging Free

A data logger is also known as a data recorder or data acquisition. It is a method to record data over a period of time and/or events.

The recorded information can come from sensors in the field. They can be digital or analog. With the analog (voltage or current) we can measure temperature, pressure, sound, weight, length, etc. Digital data can be used for counts, times, events (motor overload), etc.

A time or Event-Driven Data Logging

Data collecting can be time or event-driven. Time-based would be like collecting data every minute, shift, day, etc. An event-based collection would be from an error in the field such as an overload of a motor or a fault with a temperature controller.

Data mining / analysis is the most important part of the data logging.

Data mining/analysis is the way in which we look at the data and determine what to do. Clustering is a method to look at the data in similar groups for comparison. An example of this would be the amount of material made on individual shifts in the plant.  Setting up the data logging in a way to examine the output over time is very helpful in determining methods to increase productivity in the manufacturing environment.

Time Studies with Free Data Logging

Time studies or observations are vital in the lean manufacturing world. Data logging can be useful in assisting with these studies. However, unlike the usual manual approach, this time study can be continuous.

Doing Time Observations

Data logging does not have to be expensive. It is also not as intimidating as it may sound.

This eBook will walk you through step by step on getting information into a database so you can start analyzing the data. With traditional loggers, the software will read the memory of the PLC and store it in a local computer. If the network stops or the PLC communication fails then the logging will stop.
Creating a robust PLC data logger allows the communication to be stopped for a period of time without losing any of the data for collection. This is accomplished by storing the data locally on the PLC until communication is restored. All of the data is then read without loss. The amount of time that the connection can be lost will be dependent on the memory size of the PLC and the frequency of the data collected.
This series will walk you through the steps to create and implement a robust PLC data logger using the following equipment and hardware.
  • Automation Direct – Do-More – H2-DM1E PLC (Ethernet Modbus TCP)
  • Do-more Designer 1.3 (Simulator instead of PLC mentioned above)
  • Windows-based computer running IIS
  • Visual Basic 6
