Starting Up A Fieldbus Node; Variation 1: Start Up With The Wago Ethernet Settings; Connecting Pc And Fieldbus Node - WAGO 750-872/020-000 Manual

3.1.7 Starting up a Fieldbus Node

This chapter shows a step-by-step procedure for starting up a
WAGO Telecontrol 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.

3.1.7.1 Variation 1: Start up with the WAGO Ethernet Settings

This procedure contains the following steps:
1. Connecting the PC and fieldbus node
2. Allocation of the IP address to the fieldbus node
3. Function of the fieldbus tests

3.1.7.1.1 Connecting PC and Fieldbus Node

Connect the assembled Telecontrol 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).
