The object always shows up above the figure.
Phenomenon: I downloaded the figure above the object in XP-Builder, but the object always shows up above the figure.

5. Communication Problem
It seems that communication does not work.
Phenomenon: On the screen where the object is not many, communication works but when you move the screen where
the object is many, timeout occurs.
<Reason>
1) In the device setting, the communication time-out is set to be too short.
<Solution>
1) It occurs because timeout is set much smaller than sum of request time of communication data and response
time from PLC. In the device setting at the XP-Builder, after setting communication time out to be big, download
program and execute again.
It seems that communication doesn’t work.
Phenomenon: Communication doesn’t work.
<Reason>
1) Communication setting or cable may be not normal.
<Solution>
1) In case of RS-232C, check whether connection setting is normal or not in XP-Builder.
2) In case of RS-422/485, check whether station and communication connection setting is normal or not.
3) If 1), 2) is normal, do diagnosis about PLC-RS232C, PLC-RS485/422 at the Serial diagnosis screen of device
menu.
Refer to the [Device manual ch.5.6 Serial Communication Diagnosis]
