A function that allows the PLC to use Network Communications Instruction to
send required FINS commands to a computer connected via a Host Link
Host Link communications can be used for remote programming and remote
monitoring through a Controller Link, Ethernet, DeviceNet, or SYSMAC Link
Network. Communications across network layers can be performed.
Controller Link or Ethernet: 8 layers
DeviceNet or SYSMAC LINK: 3 layers
Direct This function enables automatically connecting to the PLC online when the CX-
Serial Programmer is directly connected by a serial connection (peripheral (USB) port
Connec- or serial port).
tion
Via Net- This function enables connecting the CX-Programmer online to a PLC that is
works connected via an EtherNet/IP network.
This function protects reading and displaying programs and tasks using pass-
words.
Write protection: Set using the DIP switch.
Read protection: Set a password using the CX-Programmer.
This function prohibits writing by using FINS commands sent over the network.
This function allows the users to give any names to the Units. Names are veri-
