3-10 Configuring the Adapter
PowerFlex® 755 Drive Embedded EtherNet/IP Adapter User Manual
Publication 750COM-UM001A-EN-P
Parameters 17 - [DL To Net 01] through 32 - [DL To Net 16] control
which parameters in the drive, adapter, or any other connected
peripheral send the values to 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:
To Net Parameter Value = (10000 * Port Number) + (Origination Parameter Number)
For example, suppose you want to use Parameter 17 - [DL To Net 01]
to read Parameter 2 of an optional I/O card plugged into drive Port 4.
Using the formula, the value for Parameter 17 - [DL To Net 01] would
be (10000 * 4) + (2) = 40002.
1. Set the values of only the required number of contiguous Datalink
parameters needed to read data from the drive and that are to be
included in the network I/O connection.
2. Reset the adapter by power cycling the drive or by using the HIM’s
Reset Device function located in the drive’s DIAGNOSTIC folder.
The adapter is ready to send output data to the master (controller). You
must now configure the controller to recognize and transmit I/O to the
adapter. Refer to Chapter
4, Configuring the I/O.
Setting the Adapter to Transmit Peer-to-Peer Data
Simple Peer I/O Configuration
The most common use of Peer I/O is to take the Logic Command and
Reference from one drive and repeat it over Ethernet to one or more
other drives. If scaling of the Reference is needed to enable drives to run
at different but related speeds, use drive Parameter 609 - [TrmPct RefA
Stpt]. The embedded EtherNet/IP adapter provides a simplified
configuration method for simple Peer I/O.
Important:Because of the 32-bit REAL (floating point) Reference, the
following method works only if the drives transmitting and
receiving are PowerFlex 750-Series drives.
To set up the master (broadcast) side of simple Peer I/O:
1. Set Parameters 89 - [To Peer Period] and 90 - [To Peer Skip] as
desired for your application. Parameter 89 controls how frequently
the adapter will transmit present data. Parameter 90 controls how
many transmit opportunities can be skipped if the data to be
transmitted has not changed.
2. Set Parameter 91 - [To Peer Enable] to a value of “1” (Cmd/Ref).
