omron recommendation

Hello all, I am working on designing the controls for a small bushing press. The customer wants a Omron PLC. I have never worked with Omron and I do not know there product line up. Can anyone suggest which model to use. I have about 40 I/O points DC/PNP and I need a 6 inch color touch screen in the system. Any suggestions are appreciated. I am assuming that the CX-One software is used for all of the Omron line including the touch screens.
Thanks
Bob

Yes Omron PLC are good to work with . If you need a 40 i/o plc then you can go with CP1H or CP1E , for touch screen you can use NS series HMI its touch and you will get colour screen . yes cx-one has cx programmer by which u can program plc.
