● 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 ZNWR 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 in (D1)
● Specify the own station's start device (D1) within the range allowed for storing write data.
(2) Function
(a) ZNWR instruction overview
The ZNWR instruction writes word device data (in and after (S1)) of the own station to word devices of the
target station (in and after (D1)).
The target station is specified in Target station network No. (Jn) and Target station No. (n1).
Upon completion of writing data to the target station devices, Completion device (D2) turns ON.
• For concurrent execution of multiple link dedicated instructions: Page 328, Section 9.2.2 (1)
