4. If you enabled one or more Datalinks, configure parameters in the drive
to determine the source and destination of data in the Datalinks.
When using Datalinks, up to 8 drive [Data In xx] parameters
(300…307) and/or up to 8 [Data Out xx] parameters (310…317) must
be assigned to point to the appropriate drive parameters for your
application. See
Chapter 4 for an example.
5. Reset the adapter (see Resetting the Adapter on page 3-7 ).
The adapter is ready to receive I/O. You must now configure the adapter to
receive I/O from the master. See
Setting Master-Slave Hierarchy .
Setting Master-Slave
Hierarchy A hierarchy determines the type of device with which the adapter exchanges
data. In a Master-Slave hierarchy, the adapter exchanges data with a master,
such as a bridge or scanner (1756-CNB/CNBR, 1747-SCNR, and so forth).
1. Enable the desired I/O in Parameter 13 - [DPI I/O Cfg].
See Setting the I/O Configuration on page 3-3 .
2. Set the bits in Parameter 25 - [M-S Input].
This parameter determines the data received from the master by the
drive. A ‘1’ enables the I/O and a ‘0’ disables the I/O.
Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.
3. Set the bits in Parameter 26 - [M-S Output].
This parameter determines the data transmitted from the drive to the
bridge or scanner. A ‘1’ enables the I/O and a ‘0’ disables the I/O.
Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.
4. Reset the adapter (see Resetting the Adapter on page 3-7 ).
