CHAPTER 13 READING/WRITING DEVICE DATA OF ANOTHER STATION CPU BY IP ADDRESS SPECIFICATION
(2) Applicable devices
The following table lists the devices whose data can be read from and written to a target CPU module using the
SP.READ/SP.WRITE instructions:

(3) How to specify the CPU module device on another station
(a) Device specification
In the device specification method, data can be read from and written to the devices within the device range of
the CPU module on the host station. To access the entire device range of the CPU module on another station,
the device range of the CPU module on the host station must be the same as that of the CPU module on
another station.
Program
Range of the CPU module
on the host station
(D = 10000 points)
D0
Data register
D9999
(b) String specification
In the string specification method, data can be read from and written to the entire device range of the CPU
module on another station. The device range of the CPU module on the host station does not have to be the
same as that of the CPU module on another station.

The value outside the range of the CPU module
on the host station cannot be specified.
