6.1 Device
Parameterisation
A complete parameterisation as well as a modification of all parameters are
executed via PC / laptop computer. The parameter data record is created by
means of the parameterisation software GW-GNET+.
Note:
Please refer to Chapter 4 for a brief instruction on the parameterisation by
means of the GW-GNET+ program. For a comprehensive description of the
parameterisation program, please refer to the GW-GNET+ online help.
6.2 Commissioning of the Gateway
The following instructions explain the commissioning of a gateway step by step.
It may be helpful to have a look at the device view in Chapter 3 from time to time
to check where the individual LEDs, interfaces and connections are located.
•
Check the installation and wiring of the
gas-net
C1 or C2 gateway in de-
energised conditions.
•
Pull off the connector marked
DSfG
on the back of the
gas-net
device. Also
pull off the connector that establishes the connection to the host (at
COM2
).
•
If necessary, consult the specifications of your DSfG bus installation for the
intended position of the end-of-line resistors. A bus termination or open-cir-
cuit generation is not necessary if exclusively
gas-net
devices are con-
nected to the DSfG bus. If you connect also other stations to the bus, other
devices must ensure the bus termination and supply. In this case, please
ask the respective manufacturer for information. Also, make sure to comply
with the regulations of the DVGW Code of Practice G 485
.
•
Connect the
gas-net
DSfG gateway to the supply voltage. Make certain that
the device contains the desired parameterisation.
•
Verify the following indications on the front of the DSfG gateway: The status
LED glows green. If the gateway is the DSfG bus master, i.e. the EADR “-“
has been assigned to it, then the
Master
LED glows. As the host has not
been connected yet, the
Host Fault
LED flashes red.
