Section 1-1 CPM1A Features and Functions 1-1 CPM1A Features and Functions 1-1-1 CPM1A Features One-piece Construction The CPM1A CPU Units feature a one-piece construction including 10, 20, 30, or 40 built-in I/O terminals. The following three model groups are available: relay output models, sink-type transistor output models, and source-type transistor output models.
Section 1-1 CPM1A Features and Functions Analog I/O Units Up to 3 Analog I/O Units can be connected to provide analog inputs and outputs. Each Unit provides 2 analog inputs and 1 analog output, so a maximum of 6 analog inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O Units. The analog input range can be set to 0 to 10 VDC, 1 to 5 VDC, or 4 to 20 mA with a resolution of 1/256. (The open-circuit detection function can be used with the 1 to 5 VDC and 4 to 20 mA settings.
Section 1-1 CPM1A Features and Functions Expansion Memory Unit The CPM1-EMU01-V1 Expansion Memory Unit is a program loader for smallsize or micro PLCs. Using the CPM1-EMU01-V1, simple on-site transfer of user programs and data memory is possible with PLCs. Uploading Downloading EEPROM SYSMAC 1-1-2 I/O Terminal and IR Bit Allocation The following table shows which IR bits are allocated to the I/O terminals on the CPM1A’s CPU Units and Expansion I/O Unit.
Section 1-1 CPM1A Features and Functions 1-1-3 CPM1A Functions Analog Setting Function CPM1A PCs have 2 variable-resistor adjustment knobs used to control analog timer and counter settings manually. When one of the adjustments is turned, the content of the corresponding IR word is set automatically between 0 and 200 (BCD). Turn the adjustment knob with a Phillips screwdriver.
