Synchronizing the Real-Time Clock
The fieldbus controller's real-time clock enables a date and time indication for
files in the flash file system.
At start-up, synchronize the real-time clock with the PC's current time.
There are two options to synchronize the real-time clock:
•
Synchronize the real-time clock using “
WAGO Ethernet Settings”
•
Synchronize the real-time clock using the
Web-based Management-
System
Synchronize the real-time clock using “WAGO Ethernet Settings”
1.
Switch off the supply voltage of the fieldbus controller.
2.
Connect the communication cable 750-920 or 750-923 respectively the
Bluetooth
®
Adapter 750-921 to the service interface of the fieldbus
controller and to your computer.
3.
Switch on the supply voltage of the fieldbus controller.
After the power is switched on, the fieldbus controller is initialized. The fieldbus
controller determines the I/O module configuration and creates a process image.
During startup, the I/O LED (red) will flash. After a brief period, the I/O LED lights
up green, indicating that the fieldbus controller is operational.
If an error occurs during start-up indicated by the I/O LED flashing red, evaluate
the error code and argument and resolve the error.
