Setting the Node Address If the adapter Data Rate switch ( Figure 2.2 ) is set to ‘PGM’ (Program), the
value of Parameter 03 - [DN Addr Cfg] determines the node address. We
recommend not to use the default node address 63 because all new devices
on the network use this address as the default address. Also, node address
63 is used for Automatic Device Recovery (ADR).
1. Set the value of Parameter 03 - [DN Addr Cfg] to a unique node
address.
2. Reset the adapter (see Resetting the Adapter on page 3-12 ).
When the node address is correctly configured and the adapter is connected
to an operational network, the NET A status indicator should be steady
green or flashing green.
Setting the Data Rate If the adapter Data Rate switch ( Figure 2.2 ) is set to ‘PGM’ (Program), the
value of Parameter 05 - [DN Rate Cfg] determines the data rate. The
default Autobaud setting will detect the data rate used on the network if
another device is setting the data rate. Your application may require a
different setting.
1. Set the value of Parameter 05 - [DN Rate Cfg] to the data rate at
which your network is operating.
2. Reset the adapter (see Resetting the Adapter on page 3-12 ).
