6.1 Reset to factory settings
The Ethernet parameters can be reset to the factory settings . Take the following steps:
►
Remove all cable connections from the evaluation unit .
►
Insert an electrically conductive bridge between pin 1 and pin 3 on the process connection IO-3 .
►
Connect the evaluation unit with the voltage supply and wait until the yellow LED indication on AUX
and IO-3 flashes at approx . 8 Hz .
►
Remove the conductive bridge from process connection IO-3 .
►
Disconnect the evaluation unit from the voltage supply and connect it again .
> The settings are reset .
6.2 Force firmware update
The firmware of the Evaluation unit can be updated directly from a PC without using an EtherCAT
controller .
Execute the following steps:
►
Remove all cable connections from the evaluation unit .
►
Insert an electrically conductive bridge between pin 1 and 3 on the process connection IO-4 .
►
Connect the evaluation unit with the voltage supply and wait until the yellow LED indication on AUX
and IO-4 flash at approx . 8 Hz .
►
Connect the evaluation unit at EtherCAT port “In” with a personal computer .
►
Open a web browser and enter the address “http://192 .168 .0 .79” .
►
Start firmware update and wait until the firmware is written to the evaluation unit .
►
Remove all cable connections from the evaluation unit .
> The firmware update is finished .
Furthermore it is possible to update the firmware over the EtherCAT controller by using the integrated
Web server of the evaluation unit or by using the FoE function of the EtherCAT protocol .
Do not interrupt power or disconnect cables from the system while the firmware update is in
progress .
