Fieldbus Node Start-up
3.1.7 Fieldbus Node Start-up
This chapter provides a step-by-step description of how to start-up a BACnet
fieldbus node. The controller must be assigned an IP address before it can
communicate properly, which can be done in one of two way:
• 3.1.7.1: Startup using WAGO-ETHERNET-Settings
• 3.1.7.2: Startup using the WAGO-BootP server
Additional Information
By default, the IP address is assigned to the BACnet/IP controller through a
BootP server.
3.1.7.1 Startup Using the WAGO ETHERNET Settings
"WAGO-ETHERNET Settings" (759-316) is a Windows application software
that can be used to read and edit bus-specific parameters of WAGO-
ETHERNET couplers/controllers. Communication cables or WAGO radio-
link adapters can be used for data communication.
The following steps are included:
• Connecting of client PC and fieldbus nodes (see section 3.1.7.1.1)
• Assigning of IP addresses to the fieldbus nodes (see Section 3.1.7.1.2)
• Testing for proper functioning of the fieldbus nodes (see Section 3.1.7.1.3)
3.1.7.1.1 Connecting Client PC and Fieldbus Nodes
1. Connect the installed BACnet fieldbus node with the configuration and
The client PC does not require a network card when connected directly, at a
serial port.
Note
The communication cable 750-920 may not be connected or removed when the
system is energized; i.e., there must be no power to the coupler/controller!
After the power is switched on, the controller is initialized. The fieldbus con-
troller determines the bus module configuration and creates a process image.
During startup, the "I/O" LED will flash red rapidly.
Assigning of IP addresses via the serial communication port
