HI EXPERTS
I HAVE LENZE P300 CONTROLLER TYPE P30GAP40300F3G0XXX-02S3C314000. I CAN MAKE BACKUP THROUGH BACKUP UTILITY. I WANT TO ONLINE WITH LENZE PLC DESIGNER SOFTWARE. I HAVE LENZE PLC DESIGNER SOFTWARE. WHEN I CONNECT P300 CONTROLLER THROUGH ETHERNET. PLC DESIGNER SHOW ME CONTROLLER BUT WHEN I CLICK ON CONTROLLER NOTHING HAPPENS MEANS NO PLC LADDER LOGIC SHOWS IN PLC. WHEN I SEARCH ON INTERNET I FOUND THAT FOR ONLINE LADDER LOGIC TROUBLESHOOTING, MUST HAVE A PLC BACKUP STORES IN YOUR LAPTOP THEN CONNECT IT THROUGH PLC DESIGNER AND GO TO ONLINE WHEN YOU DOUBLE CLICK ON CONTROLLER SHOW IN PLC DESIGNER NETWORK THEN IT WILL VERIFY WITH STORED PLC BACKUP. IF BACKUP FOUND IN LAPTIOP THEN IT ALLOWS TO CONNECT ONLINE. SO I WANT TO KNOW HOW I CAN I CRACK PLC PROGRAM BACKUP FROM CONTROLLER. BASICALLY I HAVE TO TROUBLESHOOT I/O CARDS STATUS AND ALSO WANT TO SOME CHANGE IN LADDER LOGIC. SO IS THERE ANY GUY WHO CAN TELL ME HOW CAN I ONLINE TROUBLESHOOT WITHOUT STORED PLC BACKUP OF LENZE P3OO CONTROLLER.
