Reading data from the programmable controller on another
station (with notification)
JP.SREAD, GP.SREAD
These instructions read data from a device in the programmable controller of another station. (in units of words)
After the data reading is completed by the SREAD instruction, the device of another station is turned on. The other station can
recognize that data has been read by the SREAD instruction.
