Rockwell Automation 2706 DL40 HARDWARE USER MANUAL - Manual (Page 31)

Chapter 3
The Run Mode – Remote I/O
3 – 5
To send any message to a slave, Port Use of the RS-485 Port must be set to
DL Slaves . See Chapter 4.
Message/Variable Run Mode can only be selected via the Offline
Programming Software. It is the same as the Message/Variable/Slave Run
Mode except:
•
You cannot override the slave address selected as a Message Attribute.
•
Your PLC can send up to the equivalent of 7 (not 6) full word variables if
using discrete I/O.
In the Message List Run Mode you can:
Create a List of Messages that is Continuously Displayed
The list is created by adding message numbers to the list while the DL40 is
in the Run Mode. See Chapter 10 for information for adding (or deleting)
messages via the Remote I/O Port. See Chapter 8 for additional information
for adding (or deleting) messages via the RS-485 Port or the Keyboard Port.
Important: The Message List will be lost if you leave the Run Mode, reset
the DL40, or cycle power. You will have to create a new list when you
re–enter the Run Mode. In addition:
•
Messages are displayed in the order they are put on the list.
•
Messages can be added to or deleted from the list while the list is running.
•
Messages are always added to the end of the list. If a message is deleted
and re-added to the list, it will be re-added to the end of the list.
•
You can send a Priority Message Number via the Remote I/O, RS-485, or
Keyboard port which is queued as in the Message/Variable/ Slave Run
Mode. When the message that is currently displayed finishes running, all
Priority Messages in the queue will be run. After queued messages
complete running, the DL40 resumes running the Message List.
Note: Unlike the Message/Variable/Slave Run Mode, you cannot send
variables to be included in a message.
