CHAPTER 1 CC-Link IE FIELD NETWORK

1.2 Master/Local Modules
(2) High-speed periodic communication (cyclic transmission)
Since transmission delay time is short, delay caused by the network does not need to be considered (if the link
scan time of each master/local module is shorter than the scan time of the safety CPU module).
Master/local modules can perform cyclic transmissions in combination with the following functions:
( Page 35, Section 3.3)
• Auto transfer of data between the link devices in the master/local module and the devices in the safety CPU
module
• Cyclic data assurance in units of 32 bits or per station
• Status setting (hold or clear) of input data of standard communication to which a data link error has occurred
• Station reservation for future connection, and others
