6.2 Configuration
6.2.1 Baudrate
The baudrate on a Metasys N2 network is always 9600kbps.
6.2.2 Termination
The end nodes in a Metasys network can be terminated to avoid reflections on the bus line. The OPC-G11S-
MN2 is equipped with a termination switch to accomplish this in an easy way. If the module is used as the first
or last module in a network the termination switch should be in ON position. Otherwise the switch has to be in
OFF position.
Please Note: If an external termination connector is used the switch must be in OFF position.
Termination switch ON Bus termination enabled
If the module is the last or first module,
the bus termination has to be set on, or
an external termination connector has
to be used
Termination switch OFF Bus termination disabled
6.2.3 Node Address
Before power-on the OPC-G11S-PDP the node address has to be set. This is done with the DIP-switch on the
module, this enables address settings from 1-255.
DIP switch nr. Value
1 1
2 2
3 4
4 8
5 16
6 32
7 64
8 128
Example: Setting DIP switch 1,3 and 6 to “ON” gives node address 37 (1+4+32).
Please Note: The node address can not be changed during operation.
