MTS Series 793 - Manual (Page 174)

Description Item
Important:
The total size of the fields included in a CAN message cannot
exceed 8 bytes.
When you add a static value field, you must define the static value that
is sent with the message. This static value can be read and interpreted Value (static fields only)
by a CAN device. For example, the static value may be a command that
switches a device on.
Used to add and delete fields and messages. Add/Delete
CAN Bus Input Message Settings
Each CAN input must be assigned to an input message that defines the message ID and various field settings.
To receive a message from a CAN device, the 793 input message ID must match the CAN bus device’s
output message ID and field settings.
Note:
When you use the Station Builder application to assign messages from a CANdb file to an input, most
message settings are not editable (although you can add static fields that are not associated with a
signal).
