Connecting to the CX-Programmer via the DeviceNet Section 7-1
7-1-1 Setting Node Addresses
When the CX-Programmer is connected online, it uses FINS message com-
munications. It is thus necessary to set the node address to a number other
than 0 for DeviceNet Units mounted to the target PC, DeviceNet Units
mounted to a PC which is connected by a serial connection to the CX-Pro-
grammer, or DeviceNet Units mounted to a PC relaying between networks.
If a DeviceNet Unit with the address node 0 exists in the online connection
path, connection will not be possible.
7-1-2 Setting the Message Monitoring Timer of the DeviceNet Unit
When connecting the CX-Programmer via the DeviceNet, set the message
monitoring timer inside the following DeviceNet Units to 20,000 ms (20 s).
• The DeviceNet Unit mounted to the PC with the serial connection to the
CX-Programmer.
• The DeviceNet Unit mounted to the PC relaying between networks.
Use the Configurator to set the message monitoring timer.
