Errors When Downloading

Section 8-2

The error occurred in the validation of a
device parameter.

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 Controller settings are shorter than the NE1A-series
Controller cycle time.

• The safety connection EPI is shorter than the cycle time.
• The safety inputs are set to

Test pulse from test out

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 Use

and

the other has a different setting.

• One of the safety outputs in a dual channel setting is set to

Not Use

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

“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.

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 of the NE1A-series

Controller cannot be downloaded as is. Use the following procedure to
convert the program and then download the program again.

1. Click the

Edit

Button on the Logic Tab page in the Edit Device Parame-

ters Window of the NE1A-series Controller to open the Logic Editor.

2. Select

Edit – Find Function Blocks with Open Connections

to check

all function block I/O are connected. For information on open function
block connections, refer to

Precautions Updating from Network Configu-

rator Version 1.3@ to a Higher Version

on page xxxi.

3. Select

File – Apply

to save the logic program then close the Logic Editor.

4. Return to the NE1A-series Controller’s Edit Device Parameters Window

and click the

Button.

The hardware may be malfunctioning. Cycle the NE1A-series Controller
power and execute self-diagnosis. If the MS indicator is lit red, replace the
hardware.

Logic Editor: Consistency Error.

The network configuration has changed, which has resulted in a non-align-
ment between the logic program data and other data. Start Logic Editor
and check changed I/O locations and make the settings again.

Device can not be accessed.

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

for information on TUNIDs.

With Controllers that support EtherNet/IP, use the DeviceNet Network Win-
dow for downloads. Downloads cannot be executed from the EtherNet/IP
Network Window.
