2. Maximum number of units connected to one master station (CC-Link Ver.2.00)
42 units (when connections are inverter only)
If any other units are included, the number of stations occupied depends on the unit and
therefore the following conditions must be satisfied:
{(a + a2 + a4 + a8) + (b + b2 + b4 + b8) × 2 + (c + c2 + c4 + c8) × 3
+ (d + d2 + d4 + d8) × 4} ≦ 64
{(a × 32 + a2 × 32 + a4 × 64 + a8 × 128) + (b × 64 + b2 × 96 + b4 × 192 + b8 × 384)
+ (c × 96 + c2 × 160 + c4 × 320 + c8 × 640) + (d × 128 + d2 × 224 + d4 × 448 + d8 × 896)}
≦ 8192
{(a × 4 + a2 × 8 + a4 × 16 + a8 × 32) + (b × 8 + b2 × 16 + b4 × 32 + b8 × 64)
+ (c × 12 + c2 × 24 + c4 × 48 + c8 × 96) + (d × 16 + d2 × 32 + d4 × 64 + d8 × 128)} ≦
