Configuring the Adapter
PowerFlex® 755 Drive Embedded EtherNet/IP Adapter User Manual
Publication 750COM-UM001A-EN-P
Selecting Master-Slave or
Peer-to-Peer
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 controller. In a Peer-to-Peer hierarchy,
the adapter exchanges data with one or more EtherNet/IP adapters in
other PowerFlex 750-Series drives. (The drives must have compatible
Logic Command/Status words).
For both Master-Slave and Peer-to-Peer hierarchies, the devices
exchanging data must be on the same IP subnet. See “IP Addresses” in
the
for information about IP subnets.
Setting a Master-Slave Hierarchy
Enabling Datalinks To Write Data
The controller output image (controller outputs-to-drive) can have
anywhere from 0 to 16 additional 32-bit parameters (Datalinks). They
are configured using Parameters 01 - [DL From Net 01] through 16 -
[DL From Net 16]. The number of Datalinks actively used is controlled
by the connection size in the controller. See the respective controller
example sections in
for more information on setting the
connection sizes.
Important: Always use the Datalink parameters in consecutive
numerical order, starting with the first parameter. For
example, use Parameters 01, 02, and 03 to configure 3
Datalinks to write data. Otherwise, the network I/O
connection will be larger than necessary, which needlessly
increases controller response time and memory usage.
Parameters 01 - [DL From Net 01] through 16 - [DL From Net 16]
control which parameters in the drive, adapter, or any other connected
peripheral receive the values from the network. The enhanced
PowerFlex 7-Class HIM, DriveExplorer, and DriveExecutive provide
user-friendly screens to help select the drive or peripheral by port
number and the parameter by name. As an alternate method, the
parameter value can be set manually by number using this formula:
From Net Parameter Value = (10000 * Port Number) + (Destination Parameter Number)
For example, suppose you want to use Parameter 01 - [DL From Net
01] to write to Parameter 03 of an optional encoder card plugged into
TIP: When using a ControlLogix controller and an RSLogix 5000
Add-On Drive Profile (v16 or higher), there is no need to configure
Datalink parameters at this time. They will be assigned when
configuring the RSLogix 5000 Add-On Drive Profile (see
Drive/Adapter to the I/O Configuration on page 4-5
When using a ControlLogix controller and the Generic Profile, or a
PLC-5, SLC 500 or MicroLogix 1100 controller, configure the Datalink
parameters now as described in this section.
