Chapter 4 Communication
DeviceNet Communication Option
The Powermonitor 3000 units with optional DeviceNet
communication operate as a slave device on a DeviceNet network. It
serves data to a DeviceNet master station such as a PLC-5 or SLC 500
DeviceNet scanner module, a ControlLogix DeviceNet bridge module,
a PanelView operator terminal and RSLinx direct and pass-thru
DeviceNet drivers. It supports I/O (implicit) Messaging, Explicit Server
Messaging and the explicit Unconnected Message Manager (UCMM) as
discussed below.
I/O Messaging
The power monitor supports polled, change-of-state and cyclic I/O
messaging by using assembly instances 1 for input data and 2 for
output data. The default input messaging table size is 6 integer
elements and the output table size is 2 integer elements. This
corresponds to a DeviceNet scanner mapping of 12 Rx and 4 Tx bytes.
See the Remote I/O, DeviceNet, EtherNet/IP and ControlNet I/O
Messaging Parameters table on
page 191 for the contents of the
default I/O messaging tables.
TIP
You may reconfigure the input messaging table (instance 1) by
selecting up to 23 integer or 14 floating-point parameters through a
table write to assembly instance 35.
Refer to User-configured I/O on page 122 .
If you change the size of the input table, you must also re-map the
inputs into the DeviceNet scanner by using RSNetworx for DeviceNet
software.
