Introduction Chapter 1
XM Bus
The XM Bus connector, located on each side of Dynamic Measurement
module, connects the module to the 1440-ACNR adapter and other
1440-DYN02-01RJ modules on the DIN rail, as illustrated below.
The 1440-ACNR module operates as a communication adapter for
1440-DYN02-01RJ modules. It provides an interface for controlling
XM1440-DYN02-01RJ modules on the XM Bus and transferring data to the
processor over a ControlNet network. For more information about the
1440-ACNR, refer to publication
ICM-UM001 .
The XM Bus connector passes power and XM communications between the
connected modules. The XM Bus communicates using standard DeviceNet
protocols and CAN transceivers, but it does not share the same specifications
for the media (wire) and isolation characteristics.
