noparking

Hi  I have a an Modicon M258 PLC and need to interrogate the program in order to find what is wrong with the plant! How do I upload? I understand this can be done with a memory stick. If so , will any new clean/empty stick be acceptable and is  size critical. I also have the SOMachine s/w but do not know the IP address.  I am quite nervous regarding this task as no-one has a copy of the program and the controller is used 24/7. I've phoned Schneider but "all engineers busy" Can any one out there  help

Hi Again, I sent the previous topic rather prematurely - please ignore that one. But I'm still new to Unity. I am having trouble setting up a controller in Unity and when I try and input values (picture 2) in the DATA EDITOR I get an error notification and cannot validate.   Removing these values clears the error. How do you input these values. If any one out there can reply with some help  or send me a typical example of the set-up I would be grateful. Unity_Pro_Diag2.pdf Unity_Pro_Diag3.pdf

Hi Out There, I'm new to Modicon M580 and Unity Pro and need your help!  I am trying to create a temperature controller from the Unity Pro Library.  Setting up the arameters I have come to a standstill. I cannot input the necessary parameters of the function block in the DATA EDITOR, I can put values in but then I cannot validate as errors point to these values:ERROR:Unity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdfUnity_Pro_Diag1.pdf
