To Gorp, Thank you for the HSC example. I have downloaded it and had to convert from TIA V10.5 to V11.0 SP2. I could not run the code as I do not have hardware at the moment. There is a question though about the HSC input on the CTRL_HSC block as used in FC1. According to documentation..
Gorp, in your example the HSC input has a value of 0. If I understand correctly this value should be 1. See in the PDF file where I get this number. But also.. I have opened a new project and see that this hardware identity can be different between projects. See the PDF why I say this. Therefore it is the safer route to use the system constant that has the actual value of the hardware identity. Please can someone verify my opinion for me? To Thome_sc: I am sorry for us letting you down like this. There are so many things that needs to be considered that may go wrong when using HSC. I suggest you use a button (24V) connected to the input corresponding to the HSC you wish to use. I am aiming to isolate where your problem is.. inside the PLC or outside the PLC. Please give us as much info as you can.. like a piece of your program and connection drawings. I am sure we are overlooking something.
