Errors When Downloading
Section 10-5
An error was found during parameter
check.
1. There is a non-alignment between configuration parameters. Check the following
items and change the parameters.
• The time parameters (e.g., Discrepancy Time) set for function blocks in the NE1A-
series Controllerís settings is shorter than the Controllerís cycle time.
• The safety connection EPI is shorter than the cycle time.
• The safety input channel mode is set to
Used with test pulse,
but the test source has
not been set.
• One of the safety inputs in a dual channel setting is set as a standard input and the
other has a different setting.
• One of the safety inputs in a dual channel setting is set to
Not used
and the other has
a different setting.
• One of the safety outputs in a dual channel setting is set to
Not used
and the other
has a different setting.
• The maximum number of connection IDs for one Safety Master (12) has been
exceeded in the safety I/O configuration. Change the ID allocation under
Edit Safety
Connection
−
Expansion Connection Setting
to “Check Produced IDs in the Safety
Slave” in the corresponding Safety I/O Connection (Safety Input Assembly) setting,
then download the device parameters to the Safety Master again.
2. The program may have been created with an earlier Network Configurator than
version 1.5
@
. The checks for safety functions have been improved in version 1.5
@
so
programs created in an earlier version cannot be downloaded as is. Use the following
procedure to convert the program and then download the program again.
a.
Click the
Edit
Button on the Logic Tab page in the Edit Device Parameters
Window of the NE1A-series Controller to open the Logic Editor.
b.
Select
Edit – Find Function Blocks with Open Connections
to check all
function block I/O are connected. For information on open function block con-
nections, refer to
6-3-10 Precautions When Moving from Version 1.3
@
to 1.5
@
in the
DeviceNet Safety System Configuration Manual
(Z905) for details.
c.
Select
File – Apply
to save the logic program then close the Logic Editor.
d.
Return to the NE1A-series Controller’s Edit Device Parameters Window and
click the
OK
Button.
3. The hardware may be malfunctioning. Cycle the NE1A-series Controller’s power and
execute self-diagnosis. If the MS indicator is lit red, replace the hardware.
The data used by the logic program is not
aligned with other data.
The network configuration has changed, which has resulted in a non-alignment
between the logic program data and other data. Start Logic Editor and check changed
I/O locations and make the settings again.
Could not access the device.
Device is waiting for a TUNID setting (NS indicator is flashing green/red) after reset was
executed from another node during download. Set the TUNID and download again.
Refer to
3-4-2 Network Numbers
in the
DeviceNet Safety System Configuration Manual
(Z905) for information on TUNIDs.
Could not open connection.
1. Could not establish connection with device when downloading to the device via De-
viceNet. Check that the power is ON to the device and download again.
2. The connection resources available for the device are being used to establish safety
I/O connections with the Safety Master, so a connection cannot be established with
the Network Configurator. Change the operation mode of the Safety Master to which
the safety connections are registered to IDLE mode.
3. If the above causes do not apply, noise or other factors may be making communica-
tions unstable. Check the following items.
• Do all nodes have the same baud rate?
• Is the cable length correct (trunk lines and branch lines)?
• Is the cable disconnected or slack?
• Is the terminating resistance only on both ends of the main line?
Message could not be sent.
Downloaded via USB to the device but could not connect to the device. Check that the
power is turned ON to the device and download again.
