Writing device data (SP.WRITE)
*1 Local devices and the file registers set for individual programs cannot be used.
*2 Word devices T, C, D, W, ST, SD, and SW can be specified.
*3 For information on string data specified with , refer to Page 183, Section 13.1 (2).
(1) Setting data
*4 In the "Set by" column:
"User" means that the data is set before executing the SP.WRITE instruction.
"System" means that the result of executing the SP.WRITE instruction is stored in the CPU module.
When specifying the start device by the device specification method, ensure that the CPU module on another station to
which to write data is within the range of devices available to the CPU module on the host station.
(The start device
of the CPU module on another station to which to write data) + (number of writes - 1)
≤ (the end device number of the CPU module on the host station (the end device number of the CPU module device on the
host station that has the same device name as ))
