Key Topics Covered in this Lab: Commented [JC1]: A couple more items I thought of . 1. Printing. There is a lot of flexibility with printing that I've Trending Enhancements discovered most users are completely unaware of. It is so context-sensitive that it is difficult for the user to grasp. Quick Trends We're providing a simplified interface in v13 but the context 1 ms Samples sensitive printing will still remain in tact.

2 Let me know if you'd Logging (view Trends offline or in Excel) like to discuss this more. 2. The String Browser. It is available from the Data Monitor Start, Stop Triggers for a String tag. I can elaborate if you want but you might Pre-Sampling, Post Sampling already cover it in one of your existing labs. It's a pretty slick little browser. Customize the editor, Type Ahead, Bookmarks, Quick View Pane, etc, etc. Start with the RSLogix 5000 Tips and tricks : Part 1 project that you left off with at the end of the last lab. Trending Quick Trends (new in V12). 1. This one is new in Version 12. In rung 5 of the main routine, right click on Commented [JC2]: so is the Find All.

Close the chart by click the X in the upper right hand corner of the screen. DON'T close the whole project, just the trend (only an issue if the trend is maximized): 10. The following dialog appears: 11. So far, we have only created a V12 Quick Trend. This dialog is asking if we want to create a saved trend that we'll have access to later.

5 That sounds like a good idea. Click Yes. 12. The next screen that appears is the General tab for our trend. Set the Sample Period to 100 ms instead of 10 ms, then click Next. Note: Before V12, the fastest trend Sample Period was 10 ms, but with V12, it is possible to sample as fast as 1 ms. We set our sample rate at 100 ms because it is fast enough for the tag we are trending. Getting Trend data out of the controller is the 2nd highest priority task, lower only than the Motion Task. Scan time will take about a 200 us hit for the first tag trended, with very little additional scan time taken for additional tags. The faster you want to trend data, the fewer tags you will be able to trend.

6 If you try to trend beyond the capabilities of the controller, you will notice screen updates get very _____. RSLogix5000: Tips and tricks : Part 2.

Testing is still being done, but as an example, at a 1 ms sample rate, only 1 Trend Object can be set up, with fewer than 8 tags. At a 2 ms rate, 1 Trend Object with 8 tags is possible. Even though the Trend Object is gathering the data in the 2nd highest priority task, getting that data to RSLogix 5000. happens in the Background Task. So, raising your Time Slice is sometimes necessary to allow RSLogix 5000 to get the data from the Trend Object in the controller.

7 13. We won't be changing the tag, but you could do so here. You could also add tags here, up to 8 tags per window or Trend Component. Click Finish. 14. Notice the Trend Component that shows up under the Controller Organizer: Each Trend Component uses about 4K of controller memory, no matter how many tags or how fast the sampling. Advanced Trending (more new in V12). 15. Now that the quick trend is saved, let's look at some new advanced trending features. Right click on the trend a_timer_DN Open Run the trend. 16.

Close the Excel file. 22. How much data can be captured? A lot. Open the Chart Properties and go to the Sampling tab. Before V12, all you could put in here was the Sample Period. With V12, you can define a capture based on number of Samples or based on Time Period. The third alternative is to put No Limit on the size of a capture.

9 What is a capture? It is the time between a Start Trigger and a Stop Trigger. These Triggers are the last two new tabs. Triggers start and stop data collection. Some examples: Start collecting data when my Boolean tag goes from 0 to 1. or Stop collecting data when my DINT tag has a value equal to 3.. _____. RSLogix5000: Tips and tricks : Part 2. Page 5 07/19/16. Check this radio button when you want each capture to be limited to a certain number of samples. If you reach this number of samples before the stop trigger, then the oldest data gets overwritten by the newest data. Use when the customer says, I want so many points of data.. Check this radio button when Check this radio button when you want each you want each capture to be capture to be limited to a certain time period.
