23: INTELLIGENT MODULE ACCESS INSTRUCTIONS23-2 « FC4A MICRO SMART USER ’S MANUAL »RUNA READ (Run Access Read)Applicable CPU ModulesValid Operands (Run Access Read)For the valid operand number range, see pages 6-1 and 6-2.DATA: Specify the first operand number to store the data read from the intelligent module.▲ Internal relays M0 through M1277 and AS-Interface internal relays M1300 through M1997 can be desig-nated as DATA. Special internal relays cannot be designated as DATA.When T (timer) or C (counter) is used as DATA for Run Access Read, the data read from the intelligentmodule is stored as a preset value which can be 0 through 65535.All data registers, including special data registers, AS-Interface data registers, and expansion data registers,can be designated as DATA.STATUS: Specify a data register to store the operating status code. Only data registers D0 through D1299 can be des-ignated as STATUS. Special data registers, AS-Interface data registers, and expansion data registers cannotbe designated whether the AS-Interface master module is used or not. For status code description, seepage 23-6.SLOT: Enter the slot number where the intelligent module is mounted. A maximum of seven intelligent modulescan be used.ADDRESS: Specify the first address in the intelligent module to read data from.BYTE: Specify the quantity of data to read in bytes.The RUNA READ instruction cannot be used in an interrupt program. If used, a user program execution error will result,turning on special internal relay M8004 and the ERR LED on the CPU module.Valid Data TypesFC4A-C10R2/C FC4A-C16R2/C FC4A-C24R2/C FC4A-D20K3/S3 FC4A-D20RK1/RS1 & FC4A-D40K3/S3— — X X XOperand Function I Q M R T C D Constant RepeatDATA First operand number to store read data — X ▲ X X X X — —STATUS Operating status code — — — — — — X — —SLOT Intelligent module slot number — — — — — — — 1-7 —ADDRESS First address in intelligent module to read data from — — — — — — — 0-127 —BYTE Bytes of data to read — — — — — — — 1-127 —W (word) I (integer)X XWhile input is on, data is read from the areastarting at ADDRESS in the intelligent moduledesignated by SLOT and stored to the operanddesignated by DATA.BYTE designates the quantity of data to read.STATUS stores the operating status code.DATA*****SLOT*STATUS*****BYTE***ADDRESS***RUNA(*)READWhen a bit operand such as I (input), Q (output), M (internal relay), or R (shift register) isdesignated as DATA, 16 points are used.When a word operand such as T (timer), C (counter), or D (data register) is designated asDATA, 1 point is used.
