The CTS line is not correct for the current configuration.
Disconnect and reconnect the serial port cable to the controller.
Make sure the cable is wired correctly.

Poll list error.
A fault was detected with the DF1 master’s poll list, such as specifying
more stations than the size of the file, specifying more than 255 stations,
trying to index past the end of the list, or polling the broadcast address
(STN #255).
Check for the following errors in the poll list.
•
Total number of stations is greater than the space in the poll list tag.
•
Total number of stations is greater than 255.
•
Current station pointer is greater than the end of the poll list tag.
•
A station number greater than 254 was encountered.

The ESM of a 1756-L7x controller is not installed.
If the controller is powered-down, the WallClockTime attribute and
program are not maintained.
Install an ESM in the controller.

13
The ESM installed on the 1756-L7x controller is not compatible with the
controller.
Replace the installed ESM with one that is compatible with the controller.

14
The ESM needs to be replaced due to a hardware fault.
It is not capable of maintaining the WallClockTime attribute or controller
program at powerdown.
Replace the ESM.

15
The ESM cannot store enough energy to maintain the WallClockTime
attribute or the controller program at power-down.
Replace the ESM.
