Hannari Posted March 22, 2015 Report Share Posted March 22, 2015 Hello, I have a remote IO device that among other things has a digital input that’s connected to an inductive sensor that is placed so it measures a point on a wheel. This is then transferred to my UniStream through CAN. Now I want to measure the frequency so I can then calculate the RPMs and linear velocity. I have been using Somachine (Codesys) where there is a simple frequency measure block dedicated for this. I cannot find one in UniLogic and have been trying whit various contacts, coils and timers with no luck. J Any Ideas how I can do this? Another question, can I not retain tags that are inside instances of structs? I will have multiple IO units like this one that I have made a struct of with around 40 tags. Many of these tags I need to be able to set at the HMI and keep after reboot or power failure. I cannot believe that it is not possible! Please Help.
