Is there any possibility for random addressing of DP slaves in 416 CPU (6ES7 416-2XL01-0AB0)? With Warm regards ddg |

Thanks, With this CPU I was not able to put DI , DO , AI ,AO addresses with out 0 or multiplication of 4 ( say 0 , 4, 8 ,12 ) . My intention is to put random addressing say 5, 90, 45 etc. I think I can give you more convenient picture. I already go through the following FAQ http://support.automation.siemens.com/WW/view/en/5362481 With Warm regards ddg |

Hello ddg; Well, that FAQ does state that with a morerecent CPU you would be able to address the modules as you wanted. By the way, that FAQ is dated from Y2K, so your CPU must have been on the shelf for some time now... I don't think even an operating system update is available for these CPUs. [Wrong, you can look here: http://support.automation.siemens.com/WW/view/en/2774118 but I have a doubt it would resolve the problem] Do this exercise: Open a new projet with a CPU 416 of a more recent generation, add a few DP slaves and see how you can address them. You will have the answer to your underlying question, Am I limited to 4-byte addressing because of the revision of my CPU? Hope this helps, Daniel Chartier |
