Using DeviceNet Explicit
Messaging
Chapter Objectives Chapter 6 provides information you need to monitor and configure
the SCANport device using explicit messaging on DeviceNet. In this
chapter, you will read about the following:
• Required equipment.
• Message translations.
• Messaging guidelines for the 1771-SDN scanner.
• Messaging guidelines for the 1747-SDN scanner.
• Example messages.
• Using messages to control SCANport products.
• Writing to register objects.
Refer to Appendix C, DeviceNet Objects, for information on object
data support.
Required Equipment Before using messaging, your PC must be:
• Running Logix5 and RSLinx if you are using a PLC. Refer to
http://www.software.rockwell.com for more information on these
products.
-OR-
Running RSLogix500 and RSLinx if you are using an SLC. Refer
to http://www.software.rockwell.com for more information on
these products.
• Connected to and communicating with the DeviceNet network
using a 1784-PCD card, 1784-PCID, card or a 1770-KFIO
adapter.
Explicit Message Program
Control for PLC-5 Use the Explicit Message Program Control feature to configure
device parameters on your DeviceNet network via the ladder logic
program in the PLC-5 processor that is controlling these devices.
You can use Explicit Message Program Control only with devices that
are slaves of your 1771-SDN Scanner Module. These slave devices
must be mapped in the scanner module’s scan list.
Use the Explicit Message Program Control feature to:
• Transmit configuration data from your scanner module to its slave
devices on your DeviceNet network.
