Chapter 3 Configuring the Adapter

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

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 devices. (The devices 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 (Scanner-to-Drive

Communication)

1. Enable the desired I/O in Parameter 25 - [DPI I/O Cfg].

See Setting the I/O Configuration

on page 35.

2. Set the bits in Parameter 37 - [M-S Input].

This parameter determines the data received from the master by the

device. 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 38 - [M-S Output].

This parameter determines the data transmitted from the device to the

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 43.
