Omron Sysmac Mini SP 20 Plc Programming Question


Thread Starter

Lane Williams

I recently purchased an Omron Sysmac Mini SP 20 plc off of ebay, and I have no documentation for it. I was hoping someone might have some experience or knowledge on this unit. I'm going to use it to control pumps, sprinklers, and lighting outside of my building, but I just have to figure out a way to program it. I am new to PLCs, but it seems pretty simple to me anyways. I would appreciate any and all information. Thanks in advance!! Lane
The SP20 was a small unit which only programmed through a handheld programmer. It didn't have any kind of programming software. Check with
your local Omron office, as they should all have printed manuals and such for those units. I personally had an SP10 in my office at Omron, but don't remember ever really working with it much.

i have knowledge on that plc. i'm using omrom sysmac mini SP 16 in my last project. sp 16 and sp 20 has a same microprocessor the only difference is the number of i/o. i have a software here in my computer, minilss. its support sp 10 sp16 sp 20. how can i help you.

Would you be able to send me the software or a link of where I can get it?

I would appreciate it. I have 5 sp20s

But with the cable, I have a trouble!!!! I can not comunicate with the PLC, why?, no cable!!!!
All I know about it is that includes a level adapter to rs-232 to 5v logic, but.....
