1.5 Precautions When Setting the ParametersPrecautions When Setting the Circuit Numbers1-151 Introduction1.5 Precautions When Setting the ParametersObserve the following precautions when setting the MP3200.Precautions When Setting the Circuit NumbersWhen assigning circuit numbers to the Motion Control and Communications Function Modules, the num-bers must be within the following ranges.Precautions When Setting Module Configuration DefinitionsObserve the following precautions when writing module configuration definitions.• Write the module configuration definitions only when the high-speed scan has sufficient unused pro-cessing time.Otherwise, processing may exceed the time limit of the high-speed scan.• Before writing module configuration definitions, make sure the machine is not in operation.• Before you use the Machine Controller, save any written data to flash memory and turn the power sup-ply to the Racks OFF and ON again.Unit Abbreviations of Built-in Modules CircuitnumbersFunction Modules inCPU UnitMotion ControlFunction Module SVC32, SVR32 1 to 16CommunicationsFunction Module 218IFD 1 to 8Optional ModulesMotion ModulesSVA-01 (SVA), SVB-01 (SVB01),SVC-01 (SVC), MPU-01 (MPUIF),PO-01 (PO)1 to 16CommunicationsModules217IF-01 (217IF) 1 to 16218IF-01 (218IF), 218IF-02 (218IFB),260IF-01 (260IF (DeviceNet)),261IF-01 (261IFS (Profibus)),262IF-01 (FL-net),263IF-01 (EtherNet/IP),264IF-01 (EtherCAT-S),265IF-01 (Componet),266IF-01, 266IF-02,215AIF-01 (MPLINK),215AIF-01 (CP-215)1 to 8
