REMARKS
(1) Data link transfer time (for Universal model QCPU)
Universal model QCPUs transfer interlink data in several batches.
The following are the calculation formulas for the data link transfer time.
(a) Data link transfer time taken in one END
α = KM4
L
 L
: Data link transfer time taken in one END
n1 : Number of lines where interlink transmission parameters are set
LB : Total number of link relay (LB) points set in interlink transmission
T
parameters
LW : Total number of link register (LW) points set in interlink transmission
T
parameters
KM4, KM5, KM6: Constants
1: The number of words that can be transferred in one END (N) is
restricted as follows:
N = Sequence scan time (under no interlink transmission
parameter setting) (  s)
