Hi All; Trying to make a backup of a Q02CPU. Used GXWorks2 to get the program and parameter files from the working CPU. The System is on an 8-slot rack with mixed IO including a ProfiBus module (QJ71). Got a new CPU, powered down the system and installed it after setting the DIP switches the same as the working one (2 and 3 both on, others off). Power on system. Download the program and parameters to the unit, have the ERR LED blinking and the CPU will not run. PLC Diagnostics show this 2200 error, which when I look it up in the book starts talking about 'drives', which I find out have something to do with the DIP switches. The combination of switches 2 and 3 indicate the parameters are to be stored in Standard ROM (Drive 4), but apparently this is not happening when I do the download of the program and parameters. Is there a specific procedure I need to follow to put the parameters into Standard ROM (Drive 4)? Or, did I get a replacement CPU that is either A)Bad or B)does not have this Standard ROM? Or...? Any assistance would be appreciated. CPRenaud
Hi Guys I am trying to change a profibus module on a Q02CPU from a QJ71PB92D to a QJ71PB92V, but when I try to download I keep getting the error Flash ROM writing could not execute rightly. Now I can download and upload code thus I think the Cable and PLC power OFF is a null. How would I do this? I am using GX Works 2, as I do not have GX Configurator AD. Kind Regards Morne
