The only Omron plc's i saw used a cartridge to store the pgm. the "programmer" was actullay an eprom burner with cassette ports on it to store an offline pgm. if you plc has a removeable box with a connector on the back of it (cartridge) open it up and see if it has an eprom in it . if it does you'll need the omron burner to store a ladder pgm in it. do a search for Omron on the net and i am quite sure you'll find info on it (omron's web page may still have the plc line on thier webpage, an email to the company will tell if they still have manuals on it). sorry, i have never pgmed an omron - just a ge series 6 model 60 (yes i have the industral hardened ibm luggable and all the pgms) and the westinghouse pc-1100's (yes i have all the accys for those too as well as the star tech serial/computer cassette drive) Bill Message: 10 From: "John Allain" <allain(a)panix.com> To: <cctalk(a)classiccmp.org> Subject: Omron Programmable Controller Date: Fri, 27 Jun 2003 20:34:51 -0400 Reply-To: cctech(a)classiccmp.org I have an older one here, an Omron Sysmac SCY-P5R-30E with control panel. Someone out there know something about it? I need to do basically one of the following. 1./ Find documentation so as to make it a useful member of the collection. 2./ Give it to someone that more or less needs it. 3./ Scrap it for parts. Your help appreciated. John A.
