I love your videos. Could you explain implicit message in Allen Bradley please

Once again, thanks a lot sir for all these pour wonderful and insightful tutorials, i grow each day as i feed on them. Pls, could you help me understand the relationship between the arrays created in the main routine and the CV sub routine because they have different names and so, represent different storage locations? secondly, as the input parameters have the same name in the CV subroutine, how does it allow you to enter different values for the standard deviation and average numbers. Can you have 2 different input parameters for the standard deviation and average numbers, if so, how do you use/place these two different input parameters in the CV subroutine Once again, thanks for all you do to help us sir

Hello. thanks for watching our videos 1- note that I defined one input (A) and one output (CV-Result) for my CV subroutine,. see the video, time 09:18. so, when I use JSR instruction (See time 09:35) to call the CV subroutine, I can select an Array1, Array2, or another parameter to transfer its data to input A. the CV subroutine only use data on input A to calculate its final parameter which is CV-Result. I defined this parameter as its output. so, the JSR instruction can store this parameter on any parameter like CV1, CV2, or other locations (See time 09:35)

@@plcgoodsmentor9223 Wooow Thanks alot sir. Its alot clearer although I would have loved to ow how to use array1 and array2, though I have understood the use from your explanation. Perhaps, one day, I will watch a tutorial on it. Thanks alot for your time and attention sir

[@plcgoodsmentor9223]

secondly. Please See time 09:50. suppose you stored important data on 'A', and use 'A' as the 'input par' instead of 'Array1' in the first rung. you can do it. but when the second rung is executed the data which was stored on 'A' will replaced with data on the 'Array2'. So, I prefer to use different names for parameters inside subroutines.

[@plcgoodsmentor9223]

Yes, we can have 2 or more inputs, and also 2 or more outputs. please see the video time for example time 5:14, 6:15, or 6:51. when you are 2 or more input-output parameters, pay attention to their order inside JSR, SBR, and RET instructions

@@plcgoodsmentor9223 Could you talk à little bit on what you mean by paying attention on the order sir? Do you mean something like : Input parameter2: Array1 OR Input parameter: Array2 What am looking for is how to distinguish the two input parameters in the main routine and how to use them. Thanks a lot sir
