program for programming Omron sysmac CQM!

[tlarmstr 0]

I work for an automotive supplier and we use mostly AB plc's but we have 2 machines on our floor which use Omron controllers. we have been having problems with one of the machines and are considering purchasing the software to get into the plc and possibly reprogram part of it. I called the manufacturer of the machine and they told me that they do not use the Omron programming software to program the machine they use something they developed in-house. Does this sound like it is possible. thanks

Several thoughts on this subject: 1. Omron does not publish the op-codes necessary to generate ladder code. Therefore, the company would have had to reverse engineer the code. 2. There are several integrators who have reverse-engineered the op-codes to implement a spreadsheet type of programming to generate similar but redundant lines of code iteratively. 3. Ladder is ladder is ladder. Typically any programming software will upload code generated by any other program. The rub comes when the code is parsed against a set of rules to generate the ladder display. It is possible to generate a set of opcodes that will not be displayable as ladder. 4. If you want to try before you buy, look at the LSS3 DOS package offered in the Omron download section at MrPLC.com. Note: I think they're probably lying to you.
