A1. System ConfigurationA1.1 System Configuration• Basic ConfigurationA1-1The basic configuration of FA-M3 is a unit.A unit is a system with the minimum configuration consisting of the following modules.Install these modules on the base module to compose the unit.Table A1.1 Modules (Components) of a UnitModuleDescriptionBase moduleFive types are available, allowing different numberof modules to be mounted.Power supply module A unit must have at least one power supply module.CPU moduleDifferent types are available with differentfunctionalities. A unit must have at least one CPUmodule.I/O moduleVarious types are available with different I/O andnumber of I/O points.Special moduleVarious types are available, including analog I/Oand communication modules.• Main Unit• SubunitA unit in which a CPU module is installed is referred to as a main unit. Thus a main unitis comprised of only one unit.The unit number of a main unit is 0.Subunits are used to increase the number of I/O ports. A subunit contains no CPUmodule. A maximum of seven subunits can be added to the system to handle up to 8192(depending on the CPU module type) I/O points. The unit number of a subunit is either1, 2, 3, 4, 5, 6, or 7.Main UnitI/O modules1 2 3 4 5 6 7 8 9 10 11 12 13Power CPUsupply modulemoduleAdd-on CPU moduleWith a maximum of three slotsFiber-opticFA-bus type 2modules500mmax.SubunitI/O modules1 2 3 4 5 6 7 8 9 10 11 12 13Figure A1.1 Main Unit and SubunitFA010102.VSDIM 34M06C11-01E 23nd Edition : Oct. 01, 2013-00
