corresponding size for station No. 4 RX, however, because a value
less than one word is rounded up, 1 is stored.
4200 Head buffer memory address of station No. 1 RY
H
24 (18 ) 384 (points of RY) / 16 = 24 words
H
4200 Checks the station No. 1 area because it occupies 2 stations.
H
0 (Default) Checks the station No. 1 area because it occupies 2 stations.
4218 Head buffer memory address of station No. 3 RY
H
1 (1 ) The lower 8 bits of buffer memory address 4018
H
corresponding size for station No. 3 RY, however, because a value
less than one word is rounded up, 1 is stored.
4218 Head buffer memory address of station No. 4 RY
H
1 (18 ) The higher 8 bits of buffer memory address 4018
H
corresponding size for station No. 4 RY, however, because a value
less than one word is rounded up, 1 is stored.
4400 Head buffer memory address of station No. 1 RWw
H
64 (40 ) 2 (number of occupied stations) x 32 (expanded cyclic setting) = 64
H
4400 Checks the station No. 1 area because it occupies 2 stations.
