System Design• Select a CPM2A CPU Unit, Expansion Units and Expansion I/O Units withthe specifications required in the controlled system.• Design external fail-safe circuits such as interlock circuits and limit circuits.Refer to 2-1 Specifications and 3-1 Design Precautions for details.2. Installation• Install the CPU Unit.
(Surface-mount or DIN-track installation)• Install the Expansion Unit(s) and Expansion I/O Unit(s).Refer to 3-3 Installing the CPM2A and 3-4 Wiring and Connections for details.3. Wiring• Wire the power supply and I/O devices.• Connect communications devices if necessary.• Connect the Programming Console.Refer to 3-4 Wiring and Connections for details.4. Initial Settings• Turn OFF the CPU Unit’s Communications Switch, if necessary.(When this switch is OFF, communications with devices other than theProgramming Console are governed by the settings in the PC Setup.)Preparation for OperationSection1-6• Connect the Programming Console, set the mode switch to PROGRAMmode, and turn ON the PC.• Check the CPU Unit’s LED indicators and the Programming Console’s display.• Clear the PC’s memory.
(All Clear)• Make PC Setup settings.Refer to 3-3 Installing the CPM2A for details.5. Create Ladder Program• Create a ladder program to control the system.Refer to the Programming Manual for details.6. Write Ladder Program in PC• Write the ladder program in the PC with the Programming Console ortransfer the program to the PC from the Support Software.Refer to Section 4 Using Programming Devices, to the SYSMAC SupportSoftware Operation Manuals and to the CPT User Manual for details.7.
