Enabling Local Slaves

Introduction

In a sample configuration, you will enable Local Slave 1 and Local Slave 2.

First, use these instructions to enable Local Slave 1 in the CPU’s embedded scanner service configuration. At the end of this exercise, repeat these instructions to enable Local Slave 2.

Enabling a Local Slave

Enable the CPU in the M580 local rack as a target device (local slave):

Step	Action
1	Open your M580 Control Expert project.
2	On the General tab, assign this Alias name to the CPU: BMEP58_ECPU_EXT.
3	In the DTM Browser (Tools > DTM Browser), double-click the DTM that corresponds to the alias name of the BMENOC0301.2 module to open the configuration window.
4	In the navigation pane, expand (+) EtherNet/IP Local Slaves to see the 3 available local slaves.
5	Select a local slave to see its properties. (For this example, select Local Slave 1.)
6	In the drop-down list ( Properties > Active Configuration ), scroll to Enabled .
7	Click Apply to enable Local Slave 1 .
8	Click OK to apply the changes and close the configuration window.

You now have enabled Local Slave 1 for the CPU’s scanner service at IP address 192.168.20.10.

EtherNet/IP scanners that scan the network for the CPU’s scanner service at that IP address can use implicit messages to read from and write to the assembly instances that are associated with the local slave instance.

Enabling Another Local Slave

This example uses two local slave connections. Make a second connection for Local Slave 2:

Step	Action
1	Repeat the steps above to enable a second local slave (Local Slave 2 ). NOTE: The appropriate IP address for this example (192.168.20.10) was already assigned to the CPU’s scanner service in the assignment of Local Slave 1.
2	Continue to the next procedure to configure the network scanner (originator, O).
