Instead, they open “cold,” with the action and dialogue immediately in progress after the conclusion of the preceding program. Few network TV shows now open with extended title-and-theme sequences. Thanks.TV shows don’t do that anymore, or at least they don’t do it the way Hagen and Courage and theme-writing legends like Mike Post (“Rockford Files,” “Hill Street Blues,” “Law & Order”) did it in a quainter, slower era of television. I was hoping to avoid purchasing a HandHeld Programmer but there may not be any other solution.Īgain, I appreciate any and all suggestions. I suspect that I will need to get a HandHeld Programmer to reload a plc using the audio type data file and then connect with the Dongle and software to get it to Ladder. I have the ladder programming software and Dongle (very rare), but not a HandHeld Programmer to connect to a plc for reloading purposes. Using a HandHeld Programmer is exactly what has been done so far by the person I am trying to help. But I'm interested to know how this one turns out - I mean surely there's some kind of design behind it all, but reverse engineering that pattern does not sound like the sort of thing I'd do for fun
Then use software (if it's available) or a handheld programmer or the PLC's own faceplate to scroll through the ladder and document it all.
I suspect that the easiest (and quite possible only) way of translating it would be to get hold of the PLC that uses that waveform as a backup medium, and restore it to the PLC. Unfortunately, the PLC's mind was blown even more, so by 11pm that night, it was in a skip and we had an S7-300 in it's place "Aha, the communications cable!".Įven with my exposure to some fairly old and obsolete equipment to date, that still blew my apprentice mind. He rummaged around some more and pulled out a 3.5mm jack cable. The deck had little white paint marks on the volume controls, indicating exactly where to set the volume to perform the backup and restore functions. He rummaged around some more and pulled out an old cassette deck. He rummaged around in the cupboard and pulled out a cassette. My supervisor came into the office and told me that an old GE Fanuc PLC had lost it's memory. When I was an apprentice, I saw something like this.
