When the NT11 displays an error message, find the corresponding symptoms
in the appropriate table below and respond by following the Remedy indicated
in the table.
The table below shows the errors that can occur when the power to the NT11
is turned ON and when operation starts, and their remedies.
Cause
No communication protocol has
been set.
Communication protocol and
screen data type are mismatched
- The power was switched OFF
during screen data initialization,
checking, or transmission.
- Transmission of screen data
was interrupted.
- Illegal data has been written to
the screen data memory.
No screen data is registered.
Allocated words have not been
set for the PT Status Control Area
and PT Status Notify Area.
The type of registered screen data
does not match that at the NT11.
No data is registered for either the
screen number set in the PT Sta-
tus Control Area or the Initial
Screen set with the NT Support
Tool.
Or screen numbers that do not
exist are registered.
The memory switches have been
initialized due to discovery of an
error in the memory switch set-
tings.
Remedy
Using the memory switches, set the com-
munication method to be used for commu-
nication with the host. (3-7 Setting the
Conditions of Communications with the
PLC by Using the Memory Switches,
page 71)
Initialize the screen data memory by oper-
ation at the System Menu, then re-trans-
mit the screen data. (3-4-1 Initialization of
the Screen Data, page 64)
If the problem persists, contact your
OMRON service center.
Transmit screen data from the NT Support
Tool.
Allocate words for the PT Status Control
Area and PT Status Notify Area with the
NT Support Tool and then transmit the
direct connection information to the NT11.
Initialize the screen data memory, then
transmit the correct screen data. (3-4-1
Initialization of the Screen Data, page 64)
Either specify a screen number for which
data is registered at the PT Status Control
Area, or set the screen as the Initial
Screen in the System settings under PT
Configuration at the NT Support Tool.
Set the memory switches again using the
System Menu and the System settings
under PT Configuration at the NT Support
Tool. (SECTION 3 System Menu Opera-
tion)
If the problem recurs, contact your
OMRON service center.
