Configuring the Adapter 3-3
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
Setting the Node Address If the adapter Node Address switches ( Figure 2.1 ) are set to ‘00’ (Program)
the value of Parameter 03 - [CN Addr Cfg] determines the node address.
When in any other combination of positions, the Node Address switches
determine the node address.
1. Set the value of Parameter 03 - [CN Addr Cfg] to a unique node
address.
2. Reset the adapter (see Resetting the Adapter on page 3-7 ).
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 I/O
Configuration The I/O configuration determines the data that is sent to and from the drive.
Logic Command/Status, Reference/Feedback, and Datalinks may be
enabled or disabled. (Datalinks allow you to read/write directly to
parameters in the drive using implicit I/O.) A ‘1’ enables the I/O and a ‘0’
disables the I/O.
1. Set the bits in Parameter 13 - [DPI I/O Cfg].
Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.
2. If a controller is used to control the drive, set adapter Parameters 25 -
[M-S Input] and 26 - [M-S Output] for Master-Slave Hierarchy.
For details, see Setting Master-Slave Hierarchy on page 3-4 .
3. If Logic Command/Reference is enabled, configure the parameters in
the drive to accept the Logic Command and Reference from the adapter.
For example, set Parameter 90 - [Speed Ref A Sel] in a PowerFlex 70 or
700 drive to ‘22’ (DPI Port 5) so that the drive uses the Reference from
the adapter. Also, verify that the mask parameters (for example,
Parameter 276 - [Logic Mask]) in the drive are configured to receive the
desired logic from the adapter. See the documentation for your drive for
details.
