4.2 Test mode
Setting of the test mode
The test mode is set by bringing the switches S4 and S5 in position "E". All other switches will not
be taken into consideration for the setting of the test mode. Now the Gateway has to be restarted
with these settings (by a short disconnection from the power supply).
In the test mode the Gateway always operates with the settings 9600 baud, no parity, 8 databits
and 1 stopbit.
The test mode may be helpful to integrate the Gateway in the relevant environment, for instance
to test the parameters of the RS-interfaces.
Mode of operation of the test mode
After the restart in the test mode the Gateway will be sending the values 0-15 in hexadecimal
representation ("0".."F") in ASCII-coding on the serial side every second. Simultaneously the
same values are issued binary on the fieldbus-interface.
In this mode the State-LED on the RS-side will be flashing red, the "Error No/Select ID" LEDs will
be displaying the value in a binary way, that is issued that moment. Additionally each character
that is received at one of the interfaces will also be output at the same interface as a local echo.
On the fieldbus-side only the first byte will be used for the local echo, that means on receiving as
well as on transmitting only the first byte of the bus data is looked at, the other bus data do not
change compared to the last data.
8 Bytes are output on the Ethernet interface:
The first 6 Byte are an echo of the received Ethernet data, the 7. Byte is incremented every sec-
ond 0-255 and then again from 0. The 8. Byte is also incremented every second, but always
cyclically from 0-9.
In test mode the Gateway always operates with TCP/IP (server) port 23.
4.3 Data exchange mode
The Gateway has to be in the data exchange mode, so that a data exchange between the Ether-
net-side of the Gateway and the DeviceNet is possible. As long as the Gateway is not in the con-
figuration-, test-, firmware-update-, or debug mode, the data exchange mode is active. In the
data exchange mode the Gateway will execute the downloaded Script
