6-34 Communicating with Devices on an EtherNet/IP Link

Each produced tags requires one connection for the producing controller

and an additional connection for each consuming controller. Each

consumed tag requires one connection.

Sending a MSG instruction

To send a MSG from DriveLogix1 to DriveLogix2:

1. For DriveLogix1, create a controller-scoped tag and select the

MESSAGE data type.

2. Enter a MSG instruction.

In this example logic, a message is sent when a specific condition is met.

When count_send is set, the ladder logic sends the count_msg MSG.

3. Configure the MSG instruction. On the Configuration tab:

4. On the Communication tab, specify the communication path.

Use the Browse button to select the device that will receive the MSG

instruction. The communication path in this example is:
