STPA WRITE (Stop Access Write)
Note: STPA READ and STPA WRITE instructions can be used 64 times in a user program. When more than 64 STPA READ and STPA
WRITE instructions are used in a user program, the excess instructions are not executed and error code 7 is stored in the data register
designated as STATUS.
Applicable CPU Modules
Valid Devices (Run Access Write)
For the valid device address range, see pages 6 ‐ 1 and 6 ‐ 2
(
Basic Vol.).
DATA: Specify the first device address to extract the data to write to the intelligent module.
When T (timer) or C (counter) is used as DATA for Stop Access Write, the timer/counter current value (TC or CC) is writ ‐
ten to the intelligent module.
All data registers, including special 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 with ‐
out Repeat, see page 16 ‐ 7.
STATUS: Specify a data register to store the operating status code. Data registers D0 ‐ D1999 and D10000 ‐ D49999 can be desig ‐
nated as STATUS. Special data registers and expansion data registers cannot be designated. For status code description,
see page 16 ‐ 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 STPA WRITE instruction cannot be used in an interrupt program. If used, a user program execution error will result, turning on spe ‐
cial internal relay M8004 and the ERR LED on the CPU module.
If a STPA WRITE instruction is programmed between MCS and MCR instructions, the STPA WRITE instruction is executed when the CPU
module is stopped regardless whether the input condition for the MCS instruction is on or off. For MCS and MCR instructions, see page
7 ‐ 28
(Basic Vol.)

Start input is not needed for this instruction.
When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is designated as
DATA, 16 points are used.
When a word device such as T (timer), C (counter), or D (data register) is designated as DATA, 1 point is
used.
