  1. S7 Average Function

    In the past I have used an ABB PLC to create an average of a pyrometer reading over a set length of time. I have an S7 PLC at my disposal currently and am struggling to repeat what I was able to achieve with the ABB. There doesn't seem to be a standard function for this - can anyone help with ideas or point me in the correct direction please?
  2. Edit Data Block Address Name

    Thanks for the reply. If I change the name of the address in the datablock and download the DB (while the plant is not running), does the name automatically get updated in the function block without the need for a FB download? Or do I need to download both. What is the best practice when making these type of changes?
  3. Edit Data Block Address Name

    I have used an address from a data block which is currently declared as "spare". The code change has been downloaded, is working and everything is fine. I now would like to change the name of the address to something relevant for future fault finding. I have got into trouble previously for doing this within an instance data block. My question is, once I edit the name do I need to download the datablock, the datablock and all associated functions or just save the datablock and download the functions where the address is used? Thanks
