5: SPECIAL F UNCTIONS5-72 FC5A MICROS MART USER’ S MANUAL FC9Y-B1268Forced I/OInputs can be forced on/off regardless of the status of physical inputs, and outputs can be forced on/off regardless of theladder logic using the forced I/O function in WindLDR. The force input function can be used in monitor or online editmode to test the ladder logic without the need of wiring the input terminals or turning on the actual inputs. The forceoutput function can be used to turn on/off the outputs to the external devices.The forced I/O can be used on CPU modules with system program version 200 or higher and WindLDR 5.20 or higher.Caution The forced I/O may cause unexpected operation of the MicroSmart. Make sure of safety beforeforcing inputs or outputs.DevicesAll the inputs and outputs of the MicroSmart can be forced on/off individually.CPU Module Type Device RangeInputs OutputsFC5A-C10R2, FC5A-C10R2C, FC5A-C10R2D I0 to I5 Q0 to Q3FC5A-C16R2, FC5A-C16R2C, FC5A-C16R2D I0 to I10 Q0 to Q6FC5A-C24R2, FC5A-C24R2C I0 to I15, I30 to I107 Q0 to Q11, Q30 to Q107FC5A-C24R2D I0 to I15 Q0 to Q11FC5A-D16RK1, FC5A-D16RS1 I0 to I7, I30 to I627 Q0 to Q7, Q30 to Q627FC5A-D32K3, FC5A-32S3 I0 to I17, I30 to I627 Q0 to Q17, Q30 to Q627FC5A-D12K1E, FC5A-D12S1E I0 to I7, I30 to I627 Q0 to Q3, Q30 to Q627Forced I/O StatusEvents of the MicroSmart and effects on the forced I/O settings are shown below.Events Forced I/O StatusWhen the MicroSmart starts running The force settings are retained. The forced inputs and outputs are kepton/off even after the MicroSmart is stopped, regardless of the status ofM8025 (maintain outputs while CPU is stopped).When the MicroSmart is stopped.When the MicroSmart is powered up The force settings are retained, but the force is suspended. If the bat-tery is dead, the force settings are cleared.When user program download is executed The force settings are retained, and whether the force will be sus-pended or not can be selected in the Download Program dialog box.When Run-Time Program Download or Download TestProgram is executedWhen Confirm Test Program or Cancel Test Program isexecuted The force settings are retained.When Reset Input is turned onThe force settings are cleared.When Clear All Devices is executed in the PLC Status dia-log box of WindLDRWhen the system program is upgradedRUN LEDRUN LED flashes while inputs or outputs are forced on/off.RUN LED Status DescriptionSlow Flash (1-sec interval) Inputs or outputs are forced on/off while the MicroSmart is running.Quick Flash (100-ms interval) Inputs or outputs are forced on/off while the MicroSmart is stopped.Notes: Force function has no effect on high-speed counters, catch inputs, or interrupt inputs. The stop or reset input can be initiated usingthe force function, but the force settings will be cleared as soon as the reset input is turned on. Inputs or outputs can be forced while WindLDR is in monitor mode or in online edit mode.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
