Transmission delay time of the dedicated instructions
The following is the formula to calculate the transmission delay time of the dedicated instructions.
Condition
Normal value
Maximum value
*1 When the master station is in "Normal" mode
*2 The meanings of the variables in the equation are as follows.
Variable Meaning
Rio Processing time [s]
(Number of RX/RY points)  0.026 + (Number of RWw/RWr points)  0.255 + 620 + Ka [s]
X
• Number of RX/RY points: The number of RX/RY points assigned to the remote head module in the network configuration setting of the master
module
• Number of RWw/RWr points: The number of RWw/RWr points assigned to the remote head module in the network configuration setting of the
master module
• Ka: 90  The number of mounted modules in which refresh settings are configured
The above formula calculates the average value when the number of RX/RY points is the same as the number of actual I/O
points of the module connected to the remote head module, and an auto refresh of the same number of points as the number
of RWw/RWr points was performed.
Calculation formula
Rio = 12  X
Rio = 24  X
