Reading device data (SP.READ)
*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.READ instruction.
"System" means that the result of executing the SP.READ instruction is stored in the CPU module.
When specifying the start device by the device specification method, ensure that the CPU module device on another station
from which to read 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 from which to read data) + (number of reads - 1)
≤ (the end device number of the CPU module on the host station (the end device number of the CPU module on the host
station that has the same device name as ))
