CHAPTER 2 SYSTEM CONFIGURATION
2
2.1 CC-Link IE Controller Network Configurations
2.1.1 Single network system
(1) When Universal model QCPU is used for control station
Up to 120 stations including one control station and 119 normal stations can be connected. (One control station is
needed for a single network.)
*1 The receive range for other station's data varies depending on the CPU module. ( Page 65, Section 4.1.1 (5))
*2 The receive range for other station's data varies depending on the CPU module. ( Page 68, Section 4.1.2 (5))
(2) When other than Universal model QCPU is used for control station
Up to 64 stations including one control station and 63 normal stations can be connected. (One control station is
needed for a single network.)
*1 The receive range for other station's data varies depending on the CPU module. ( Page 65, Section 4.1.1 (5))
*2 The receive range for other station's data varies depending on the CPU module. ( Page 68, Section 4.1.2 (5))
*3 A station with a Basic model QCPU or safety CPU operates as a normal station. (It cannot be set to a control station.)
