Hi I am a new Omron user....and I wanted to know what CPS files are and how can I get CPS_CS1H_CPU66H_ver4_0.xml file...because that is the error I get when I try to open a program.....What i want to do is when I try to add my I/O cards in the I/O config I can not find my cards in the list... they are C200H_ID212 and C200H_OD 212. Thanks for the help.
