Hi! I found Omron PLC CQM1H-CPU21, but I don't have a cable for him. In pictures cable looks like simple RS232 cable. PLC will work with simple RS232 cable?

So I can make my own with this schematic, or there also has some micro chips inside?

Yes, you can make your own. This is a simple RS232C connection. The CQM1-CPU21 has a built in serial port so you can use this cable. Choose SYSMAC WAY for your Network Type, default Omron settings are 9600, 7, E, 2. Alternatively, you can purchase the CQM1-CIF02 Omron cable. This cable has the electronics inside for protocol conversion and would utilize the Peripheral Port. Edited 29 Nov 2012 by IO_Rack
