23: INTELLIGENT MODULE ACCESS INSTRUCTIONS
« FC4A MICROSMART USER’S MANUAL » 23-3
RUNA WRITE (Run Access Write)
Applicable CPU Modules
Valid Operands (Run Access Write)
For the valid operand number range, see pages 6-1 and 6-2.
DATA: Specify the first operand number to extract the data to write to the intelligent module.
When T (timer) or C (counter) is used as DATA for Run Access Write, the timer/counter current value is
written to the intelligent module.
All data registers, including special data registers, AS-Interface data registers, and expansion data registers,
can be designated as DATA.
When a constant is designated as DATA, Repeat cannot be selected. For details about the data movement
with or without Repeat, see page 23-7.
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 cannot
be designated whether the AS-Interface master module is used or not. For status code description, see
page 23-6.
SLOT: Enter the slot number where the intelligent module is mounted. A maximum of seven intelligent modules
can be used.
ADDRESS: Specify the first address in the intelligent module to store the data.
BYTE: Specify the quantity of data to write in bytes.
The RUNA WRITE 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.
