Description
Item
The name that appears in the CAN Bus Editor’s navigation tree.
Name
Note:
Once you click Apply Name to add the message to the navigation
tree, you will not be able to edit the name or port setting.
Identifies the controller CAN bus port (that is connected to the CAN bus
network) where the device(s) that will receive or send the message are
connected.
Port
The Message ID used in a Series 793 output message allows a CAN
device to identify a message and take appropriate action.
Message ID
If a CAN device must read an output message, the CAN device must
have an input message with the same message ID and field definitions
as the Series 793 output message. If not, the CAN device will ignore the
output message.
Set the rate (Hz) at which the output message is sent.
Rate
Select the RTR Frame check box in an output message to create a
remote data frame (RTR) message. This type of output message sends
a request (to a CAN device) for data in the form of a message.
RTR Frame
Important:
Do not define any data fields for RTR Frame messages.
The Message ID setting set in the RTR Frame output message
determines which CAN device(s) respond to the request. To respond to
the RTR Frame message, the CAN device requires an input message
with the same message ID as the RTR Frame message.
Describes an output message that responds to an incoming RTR frame
from a CAN device. When an RTR Frame message with the same
message ID is received, the RTR Data message is sent.
RTR Data
Note:
Typically, a message marked as RTR Data should have a rate of
0 Hz because it is not sent periodically.
Shows all the fields that will be sent with the message. These fields can
include CAN outputs that were assigned to the message or static fields.
Fields settings
For more information on field settings, see
