Troubleshooting Diagram 15
Did you make sure of
source 1 device of the TXD
instruction?
Are communication
parameters set correctly
using WindLDR?
Are inputs to more than
5 TXD instructions on
simultaneously?
Correct the program to make sure that inputs to
more than 5 TXD instructions do not go on
simultaneously.
Data is not transmitted correctly
in the user communication mode.
Set the communication parameters to match those
of the remote terminal using WindLDR. See
"Programming WindLDR" of the basic volume
(page 10-5).
Make sure that the busy signal at the remote
terminal does not exceed 5 sec.
Is the data register designated
as transmit status used
repeatedly?
Correct the program to replace the duplicate data
register with a different data register.
Is duration of the busy
signal at the remote
terminal less than 5 sec?
Make sure that the transmit data designated as
source 1 device is correct.
When the user communication still has a problem after completing the above procedure, also
perform the procedure of Diagram 14 described on the preceding page.
