I am working on a SLC 5/03 processor that lost its program.I downloaded to the Allen Bradley SLC 5/03 through the RS232 connector the backup program. The downloading was done successfully and the PLC indicating running now.A PC being used for graphics is connected to the PLC through the RS232 port. A provision was also made for connecting the programming terminal to the PLC through DH485 port (RJ45 Connector).The PC is still indicating fault while the PLC is running. This I believe can be attributed to the fact that I had the program downloaded through the RS232 port using AB-DF1-1 driver while the driver in the initial program backup is AB_PIC_1.Anytime I try downloading the backup program to the PLC, the information below is shown to which I affirm in the negative:Current Project Settings do not match system settings.Current Driver – AB_PIC_1 Driver Selected – AB_DF1_1Current Node – (1Dec) Node Selected – (1 Dec) Would you like to replace project settings with new settings?Checking the downloaded program online then show that the driver is AB_DF1_1 different from AB_PIC_1 as in the original program.I have a 1747-PIC which could be used to communicate with the PLC through the RJ port but unfortunately the PC connector end is 25 pin female which cannot fit to my laptop.This is the situation I have at hand. Can somebody help? It will definitely be most appreciated.
