Procedures for Connecting Online to a PLC
Either of the following two procedures can be used to connect online to a PLC from the CX-Program-
mer.
Change PLC Dialog Box
Set the method for accessing the target PLC for the CX-Programmer project. This setting is made
when creating the project, but it can be changed after the project has been created.
Automatic Online Connection
An automatic online connection is used to access a PLC for which a connection has been estab-
lished. It can be used without creating a CX-Programmer project.
Direct Connection
Direct connection is used to connect online to a PLC connected directly to the CX-Programmer
through a serial port.
EtherNet/IP Node Connection
An EtherNet/IP node connection is used to access a PLC for which a connection has been estab-
lished through EtherNet/IP. Even if the IP address of the target PLC is not known, the PLC can be
accessed by searching for it.
