10–24 Communicating with an SLC 5/03 Processor on a DeviceNet Network using Explicit Messaging
Publication 2755-6.8
Use the Explicit Message Program Control feature to configure
device parameters on your DeviceNet network via the M0 and M1
files in the SLC processor that is controlling these devices.
You can use Explicit Message Program Control only with devices
that are slaves of your 1747-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
•
receive status and diagnostics from these devices on your
DeviceNet network
•
make runtime adjustments to device parameters according to
changing conditions detected by your processor
