Enabling Local Slaves

Introduction

In a sample configuration, you will enable Local Slave 4 and Local Slave 5.

First, use these instructions to enable Local Slave 4 in the BMENOC0301 module configuration. At the end of this exercise, repeat these instructions to enable Local Slave 5.

NOTE: This example uses a BMENOC0301 module. Use the same instructions for other M580 communications modules (like the BMENOC0311 or BMENOC0321).

Enabling a Local Slave

Enable the BMENOC0301 module in the M580 local rack as a target device ():

Step	Action
1	Open a Modicon M580 Control Expert project.
2	Add a BMENOC0301 module to slot 3 in the local rack.
3	On the General tab, assign this Alias name to the BMENOC0301 module: BMENOC0301_slot3
4	In the DTM Browser (Tools → DTM Browser), double-click the DTM that corresponds to the alias name of the BMENOC0301 module to open the configuration window.
5	In the navigation pane, expand (+) EtherNet/IP Local Slaves to see the available local slaves.
6	Select a local slave to see its properties. (For this example, select Local Slave 4.)
7	In the drop-down list (Properties → Active Configuration), scroll to Enabled.
8	Press Apply to enable Local Slave 4.
9	Press OK to apply the changes and close the configuration window.

You now have enabled Local Slave 4 for a BMENOC0301 at IP address 192.168.20.10.

EtherNet/IP scanners that scan the network for the BMENOC0301 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 5:

Step	Action
1	Repeat the steps above to enable a second local slave (Local Slave 5). NOTE: The appropriate IP address for this example (192.168.20.10) was already assigned to the BMENOC0301 module in the assignment of Local Slave 4.
2	Continue to the next procedure to configure the network scanner (originator, O).
