CHAPTER 9 DEDICATED INSTRUCTIONS

9.5 JP/GP.WRITE (Data Write to Programmable Controllers on Other Stations)
● Specify devices of the target station's CPU within the range allowed for the own station CPU when writing data to the
devices with the WRITE instruction.
(Target station's start device (D1) to which data are written) + (Write points - 1) (End device No. of own station's CPU
*1
)
*1 End device No. of the device in the own station CPU, and whose device name is same as (D1)
● Specify the own station's start device (D1) within the range allowed for storing write data
● Use the file register (ZR) when specifying the extended data register (D) or extended link register (W) that is outside the
area of the own station CPU's data register (D) or link register (W). (Except for the Universal model QCPU)
For the calculation of the file register (ZR), refer to the following.
When D150 and after the area in the own station's CPU has been already used
User's Manual (Function Explanation, Program Fundamentals) for the CPU module used
When 0K point is assigned to the data register (D) of another station (Example) When 0K point is assigned to the
data register (D) of another station CPU, and when all 32K points of the file register (ZR) are assigned to the
extended data register (D)
Ex.
Good example (D50 is specified to (D1).) Bad example (D100 is specified to (D1).)
