Intelligent device station
(station No.: 1, Number of
occupied stations: 1,
extended cyclic setting: octuple)
Remote Net Ver.2 mode
Value Description
4000H Start buffer memory address of RX in the station number 1
128 (number of points of RX)  16 = 8 words
8 (8H)
4008H Start buffer memory address of RX in the station number 2
4 (4H) The corresponding size of RX whose 4 words of the buffer memory address: 4008H to 400BH
are the station number 2
4000H Because the station occupies two stations, check the area in the station number 2.
0 (Default) Because the station occupies two stations, check the area in the station number 2.
400CH Start buffer memory address of RX in the station number 4
2 (2H) The corresponding size of RX whose 2 words of the buffer memory address: 400CH to 400DH
are the station number 4
4200H Start buffer memory address of RY in the station number 1
128 (number of points of RY)  16 = 8 words
8 (8H)
4208H Start buffer memory address of RY in the station number 2
4 (4H) The corresponding size of RY whose 4 words of the buffer memory address: 4208H to 420BH
are the station number 2
4200H Because the station occupies two stations, check the area in the station number 2.
0 (Default) Because the station occupies two stations, check the area in the station number 2.
420CH Start buffer memory address of RY in the station number 4
2 (2H) The corresponding size of RY whose 2 words of the buffer memory address: 420CH to 420DH
are the station number 4
4400H Start buffer memory address of RWw in the station number 1
32 (20H) 1 (number of occupied stations) × 4 words × 8 (extended cyclic settings) = 32
4420H Start buffer memory address of RWw in the station number 2
8 (8H) 2 (number of occupied stations) × 4 words = 8 buffer memory area size of RWw in the station
number 2
4400H Because the station occupies two stations, check the area in the station number 2.
0 (Default) Because the station occupies two stations, check the area in the station number 2.
4428H Start buffer memory address of RWw in the station number 4
0 (Default) Buffer memory area size of RWw in the station number 4
4C00H Start buffer memory address of RWr in the station number 1
32 (20H) 1 (number of occupied stations) × 4 words × 8 (extended cyclic settings) = 32
4C20H Start buffer memory address of RWr in the station number 2
8 (8H) 2 (number of occupied stations) × 4 words = 8 buffer memory area size of RWr in the station
number 2
4C00H Because the station occupies two stations, check the area in the station number 2.
0 (Default) Because the station occupies two stations, check the area in the station number 2.
4C28H Start buffer memory address of RWr in the station number 4
0 (Default) Buffer memory area size of RWr in the station number 4
Remote device station
