Run
In the Run state, BASP is deactivated and process data communication is started via the ricos FLEX
backplane bus. The Ethernet coupler copies the output data received from the client (master sys-
tem) to its output modules and forwards the input values to the client.
Commissioning
Only in this state is it possible to save and delete the configuration in the Ethernet coupler. Here you
can parametrize the Ethernet coupler and the connected modules via the web server. This will disa-
ble BASP. Only in this state is write access to the process output data possible via the web server. In
this state Modbus/TCP requests are returned with an error. Also, you can only perform a firmware
update via the web server in this state. For the firmware update, the Ethernet coupler switches to
the state Firmware update. Firmware update.
Please note that the outputs are reset when changing to and from the 'Commissioning' state.
NOTICE
Maintenance
This state is automatically activated in the case of physical changes to the backplane bus or in the
event of a bus error. This activates BASP and stops the process data communication. Modbus/TCP
requests are returned with an error. As soon as the bus error is corrected or the physical structure
corresponds to the configured structure, the Ethernet coupler automatically changes to the state
Update config.
Firmware update
In this state, a firmware update is performed. This activates BASP and stops the process data com-
munication. Modbus/TCP requests are returned with an error. After the firmware update a restart
takes place and the Ethernet coupler changes to the state Init. If no firmware update could be done,
the Ethernet coupler changes to the state Update config.
Error
Condition that exists when at least one of the following criteria is met:
•
•
•
•
This activates BASP and stops the process data communication. Modbus/TCP requests are returned
with the corresponding error.
