I have a customer who has a Modicon 484. The power supply went bad and the program got scrambled. They had spare parts to get it running but without a program. I was able to use their P180 programmer to add some rungs and verify the 484 operation. They have a cassette tape backup. But nobody knows cable configuration, bauds, etc. The tape loader they have is a STR-Link. I was unable to get program loaded in. Anybody have any suggestions?
