Posted 21 Jan 2020 I need help configuring high speed input in my project. As high speed input I am using proximity switch and I connected it to Digital Input 0 of CT021 (Pin 5 on image) So how can I know what is adress of my DI0 from that module? How can I know when DI0 goes on? This is my main problem because I don't know the adress of that digital input. If I knew the adress I would than easily link it to some counter and see if it is counting Share this post Link to post Share on other sites
Posted 21 Jan 2020 Please refer to manual W401. That is the manual for the CT021. Addressing will depend on the Machine or Unit Number of the module. Share this post Link to post Share on other sites

I saw the manual but am still confused. My unit number is 24 so can you tell me how can I read when DI0 of module goes high? Share this post Link to post Share on other sites
Posted 21 Jan 2020 n is a variable used in the manual to represent the starting address for the data exchange area for the card in the CIO area. n = 2000 + 10 x Unit number. n in your case is then 2240. If you are trying to look at input I0, it would be 2256.00 (2240 + 16, bit0). 1 person likes this Share this post Link to post Share on other sites

Now, how can I use this DI to count number of pulses each second? Is it enough to use timer of 1s that counts number of pulses? Or can I use "PRV" block for HSC? If so, how I configure it? What does port specifer means? How can I connect my digital input to "PRV" block? Share this post Link to post Share on other sites
