Setex plc

Does anyone know of any software that you would use for a setex plc? We have about 30 of them on some dye equipment, and they are very secret about the software, claim you can not buy it only folks that work for setex. I have watched one of the techs and the software was labeled plc-lab. I have searched for it but can not locate it.
Any suggestions?

I have never heard of that brand but just a quick google search got me a good pdf file and the setex website. It looks to the software is called orgatex? use google with keywords setex plc-lab software.
