3-8 Configuring the Adapter

20-COMM-E EtherNet/IP Adapter User Manual

Publication 20COMM-UM010G-EN-P

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.

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 3-16).

The adapter is ready to receive I/O. You must now configure the adapter to

receive I/O from a master or peer device. See Selecting Master-Slave or

Peer-to-Peer Hierarchy. If you select a Master-Slave hierarchy, you must

also configure the master to communicate with the adapter. See Chapter

Configuring the I/O

Selecting Master-Slave or

Peer-to-Peer 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 (1756-ENBT, 1756-EN2T, 1747-L5-xxx, and so

forth). In a Peer-to-Peer hierarchy, the adapter exchanges data with one or

more EtherNet/IP adapters in other 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 Glossary

for

information about IP subnets.

Setting a Master-Slave Hierarchy (Scanner-to-Drive Communication)

1. Enable the desired I/O in Parameter 23 - [DPI I/O Cfg].

See Setting the I/O Configuration

on page 3-7.

2. Set the bits in Parameter 35 - [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.
