 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)} ≤ 2048
