Reset the adapter by power cycling the drive.
Using 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
scanner or bridge.
For a Master-Slave hierarchy, the devices exchanging data must be on the same IP
subnet. See “IP Addresses” in the
for information about IP subnets.
Configuring a Master-Slave Hierarchy
The controller I/O image can have anywhere from zero to eight (four In and four
Out) additional 16-bit parameters called Datalinks. They are configured using
parameters C153 [EN Data In 1] through C156 [EN Data In 4], and C157
[EN Data Out 1]
through C160 [EN Data Out 4]. The number of Datalinks
actively used is controlled by the connection size in the controller and the in/out
parameters. See the respective controller example sections in
for more
information on setting the connection size.
When using a ControlLogix or CompactLogix controller and the Generic
Profile, or a MicroLogix 1100/1400 controller, configure the Datalink
parameters now as described in this section.
TIP
Auto detection of data rate and duplex works properly only if the
device (usually a switch) on the other end of the cable is also set to
automatically detect the data rate/duplex. If one device has the data
rate/duplex hard-coded, the other device must be hard-coded to the
same settings.
TIP
When using a ControlLogix or CompactLogix controller and an RSLogix 5000
(version 17 or greater) or Logix Designer (version 21 or greater) drive Add-On
Profile, there is no need to configure Datalink parameters at this time. They
will be assigned when configuring the drive Add-On Profile (see
