C-more HMI: Collecting Data and Data Logging Overview from AutomationDirect

C-more offers many ways to display and modify data, but this HMI offers an advantage. You can also capture and log data that could be missed during the running process. This data can then be stored to an external SD card or USB drive and evaluated later. There are 5 ways to capture and store data in the C-more. There are detailed videos on each of these methods that can be found in the playlist at the end of this video. You can grab screen captures, with the values on a screen, at any given time. This is helpful if you need a complete picture of a process, at the moment of failure or other important trigger. These are 4 datalogging options. These options create a CSV log file that are a day long and end at midnight each day. There can be a total of 18 log files. 1 for you Alarm Log, 1 for Message Database and up to 16 log files for either the Line Trend Graph or the PID Faceplate Line Trend Graph. The Alarm Log captures all the alarm events that has this option selected. This is a good catch all data logging option. If you want to log when a failure or any other important process point has happened, this is where you will log that information. The Message Database Logs include messages, from the message database, that has this option selected and then is triggered through the lookup text option. This database also includes the messages from the multi-state text object that has this log option checked. With screen captures, message database and alarm database, you can select where these are stored from the panel manager. The default storage location is SD1, and dependent on your C-more model you can select one of these 3 options. The Line Trend Graph is a data collection that is tied to the line trend graph object. These line trend graph object will log if you have this option selected. The logging on Line Trend Graph is a great way to do a deep dive evaluation on a process to see what can be causing an issue or how it can be improved. The PID Faceplate Line Trend Graph is just like the regular Line Trend Graph, but specifically designed with a PID process in mind. So, those are the different ways you can capture and log data with C-more. If you want more information on any of these, please follow this playlist for a more in-depth video.
