RDI Posted September 16, 2014 Report Posted September 16, 2014 Hello. I have a C20-CPU34E and a PRO15 prgramming console. I'm trying to figure out the lest expensive way to connect to another C20 and download a program that I will then upload into my C20. I'm a newbie to this in general and have no experience with equipment this old So far what I've seen as options from the C20 maual I found are: 1) Use Syswin and a hostlink unit to go from the CPU to a modern PC. Unfortunately I'd have to make my own cable and the hostlink units are going for about $900. 2) Use the programming console I have and try to dump the program to a cassette recorder, then upload the same way. Cassette media makes me nervous. 3) Buy a GPC and connect with a custom cable to the C20 CPU to download and then upload the program. Not sure about these options: 1) Use a 3G2A5-MT01E cassette interface. Does this plug into the CPU and the go out to a recorder the same as the PRO15 console does? 2) Use a PRW04-E prom writer. Does this plug intot he CPU and record the program to EPROM? Then I could upload to the other C20? Anyway, there are a lot of options, some of which I don't understand fully. I', looking for easy and inexpensive. Can anyone with Omron experience help me out? Thanks in advance! Quote

Michael Walsh Posted September 16, 2014 Report Posted September 16, 2014 Outside of replacing it (which is the best option), option #1 shown below is your only real option these days. 1) Use Syswin and a hostlink unit to go from the CPU to a modern PC. Unfortunately I'd have to make my own cable and the hostlink units are going for about $900. Then you could upload your program to Syswin and eventually convert it to a CP1L PLC or something similar (using CX-Programmer software). Quote
RDI Posted September 16, 2014 Author Report Posted September 16, 2014 That's the plan AFTER I get a copy of the ladder diagrams so I don;t have to program the machine from scratch. Quote
RDI Posted September 16, 2014 Author Report Posted September 16, 2014 I should have been more clear in my first post. I have a C20 but the backup battery died and it dumped the program. I want to hook up to another machine with a c20 and get a copy so I can upload it onto my first machine. If I have to reprogram from scratch I'm looking at a long process.... Quote
Jay Anthony Posted September 16, 2014 Report Posted September 16, 2014 The cassette method is reliable and could be used to do exactly what you propose. Do you have a C20 operation manual? Quote
RDI Posted September 17, 2014 Author Report Posted September 17, 2014 Yes, Jay, I found an old C20 manual online and have been learning from it. I might have to get a cassette recorder again though! Quote
