RUNA READ (Run Access Read)
Applicable CPU Modules
Valid 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 intelligent
module 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 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 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.

While input is on, data is read from the area
star ting at ADDRESS in the intelligent module
designated by SLOT and stored to the operand
designated by DATA.
BYTE designates the quantity of data to read.
STATUS stores the operating status code.

When a bit operand such as I (input), Q (output), M (internal relay), or R (shift register) is
designated as DATA, 16 points are used.
When a word operand such as T (timer), C (counter), or D (data register) is designated as
DATA, 1 point is used.
