This chapter shows a step-by-step procedure for starting up a
WAGO ETHERNET TCP/IP fieldbus node.
A prerequisite for communication with the controller is the assignment of an
IP address. For this two different variations are described:
-
-
Additionally in the following chapters, it covers details regarding PFC
programming with WAGO-I/O-PRO CAA and provides information about the
built-in HTML web pages.
This procedure contains the following steps:
Connect the assembled ETHERNET TCP/IP fieldbus node on your PC with
the communication cable (Item-No. 750-920) between the controller's
configuration and programming interface and a free serial PC port.
Warning
The communication cable 750-920 must not be connected or disconnected
while the coupler/controller is powered on!
Once the operating voltage has been switched on, the PFC initialization starts.
The fieldbus controller determines the configuration of the I/O modules and
creates the process image. During the startup the 'I/O' LED (Red) flashes at a
high frequency.
When the I/O LED turns green, the fieldbus controller is ready for operation.
If an error has occurred during startup, a fault code is flashed on the
'I/O'-LED. If the I/O LED flashes 6 times (indicating error code 6) and then 4
times (indicating error argument 4), an IP address has not been assigned yet.
Variation 1: Start up with the WAGO Ethernet Settings
(offers a comfortable fast IP address assignment over the serial
Configuration interface of the controller)
Variation 2: Start up with the WAGO BootP Server
(IP address assignment over the field bus, whereby compared with
Variantion 1 several steps are necessary).
