Token hold time (ms): Token holding time of the self-node
Token hold time = 1.6 + 0.0036 × S + 0.0029 × R + 2.47 × F + MFT
Token hold time = 1.6 + 0.0036 × S + 0.0029 × R + 2.47 × F
Token hold time = 1.6 + 0.0036 × S + 0.0029 × R + (0.87 + MFT) × F + MFT
Token hold time = 1.6 + 0.0036 × S + 0.0029 × R + (0.87 + MFT) × F
Refresh cycle time (ms): Sum of the token hold time values of all the nodes.
Refresh cycle time = 1.6 × n + 0.0065 × W + 2.47 × (F1 + F2 + F3....... + Fn) + MFT × n
Refresh cycle time = 1.6 × n + 0.0065 × W + 2.47 × (F1 + F2 + F3....... + Fn)
Refresh cycle time = 1.6 × n + 0.0065 × W + (0.87 + MFT) × (F1 + F2 + F3 ...... + Fn) + MFT × n
Refresh cycle time = 1.6 × n + 0.0065 × W + (0.87 + MFT) × (F1 + F2 + F3 ...... + Fn)
Cyclic transfer throughput (ms)
Time from setting data in the memory of the transmitting side CPU to calculation by the
ladder program of the receiving side CPU.
Cyclic transfer throughput = RCT + SCT ...........................................[For ladder processing]
Cyclic transfer throughput = RCT .......................................................[For C mode processing]
..............[When 0 ≤ MFT < 2 and R ≤ 512]
