Processing details
This instruction writes data to devices of a programmable controller CPU on another station. (In units of words)
• Specify devices of the target station's CPU within the range allowed for the host station CPU when writing
data to the devices with the ZNWR instruction.
(Target station's start device number (d1) where data are written) + (Write points - 1) (End device No. of host
station's CPU
• Specify the host station's start device number (d1) within the range allowed for storing write data. (Example)
When D150 and after the area in the host station's CPU has been already used
