Standard station
This section shows the formulas to calculate the following cyclic transmission delay time.
• The time between when the transmission source CPU module device turns on or off and when the transmission destination
CPU module device turns on or off
• The time between when data is set in the transmission source CPU module device and when the data is stored in the
transmission destination device
• When "Communication Period Setting" of the communication destination is set to any setting other than
"Basic Period" in "Network Configuration Settings" under "Basic Settings" of the master station, multiply the
multiplication specified in "Multiple Period Setting" under "Communication Period Setting" of "Basic
Settings" by LS (communication cycle intervals) according to the setting.
■ Master station  remote station
When data is transmitted from a remote station (input) to the master station (RX/RWr).
