Memory Map
Buffer memory assignment pattern 2
Remote registers (RWrm, RWwm) are mainly used, and up to 256 input points and 256 output points can be assigned.
1 to 4 stations can be occupied.
Remote input (SL-VGU1-C → master)
Input: 256 points (4 occupied stations) Input: 256 points (4 occupied stations) o = 7
Input: 192 points (3 occupied stations) Input: 192 points (3 occupied stations) o = 5
Input: 128 points (2 occupied stations)
Input: 128 points (2 occupied stations) o = 3
Input: 64 points
(1 occupied station)
Input: 64 points (1 occupied station) o = 1
