    The CPM1 PCs conform to EC directives (EMC and low-voltage directives), so they can be incorporated in equipment destined for the EC. Contact your OMRON representative for more details. Input Interrupts The CPM1-10CDR-j PCs can handle 2 interrupt inputs; the CPM1-20CDR-j and CPM1-30CDR-j PCs can handle 4 interrupt inputs.
  • Page 19 Standard Peripheral Devices The CPM1 uses the same Programming Consoles, SYSMAC Support Software (SSS), and Ladder Support Software (LSS) as the Mini H-type and CQM1 PCs. Programming is Possible Programming operation is possible through the PT screen by using an OMRON Using the PT PT that has a built-in Programming Console function.
  • Page 20 Section 1-1 CPM1 Features and Functions 1-1-3 CPM1 Functions Analog Setting Function CPM1 PCs have 2 analog volume controls that can be used to make analog timer and counter settings manually. When one of the volume controls is turned, the content of the corresponding IR word is set automatically between 0 and 200 (BCD).
  • Page 21 Section 1-1 CPM1 Features and Functions Input Interrupts The CPM1-10CDR-j PCs have 2 interrupt input terminals and the CPM1-20CDR-j and CPM1-30CDR-j PCs have 4 interrupt input terminals. There are two modes for input interrupts: input interrupt mode and counter mode. 1, 2, 3...
