(VID-DD-0031) - This video gives basic information on Using the RANDSEED "Random Number Seed" instruction in the Do-more Designer software. It presents information that is commonly missed by users. This WILL NOT be a complete tutorial for the instruction but rather a supplement to the help file and customer experience.
** Software Version used in this video: Do-more Designer 2.0
This instruction is used to create a random seed that then can be used In the Random Integer or Random real Math operations. If you use a set number value in the seed, your random number generation will follow the same number patterns each time. To obtain the most randomized operation it is best to use a changing seed value. I find it best to use the Time in the PLc as the Random seed. DST21 is what I typically use. This is the time, of the PLC, in 1970 Epoch Format.
