Posted 13 Sep 2017 You need to give information about the controller model and the analog modules only on the ladder diagram, it's hard to guess it. Share this post Link to post Share on other sites
Posted 13 Sep 2017 U/G addresses are used to access the buffer memory inside a special module. You will need the manual for the special module to see how its memory is arranged. The U portion of the address is the starting address of the module, such as U3 for the module whose address starts at 30. The G portion is the buffer number being accessed inside the module.
