Cause
The error code denotes a controller error
(NAK).
1) When the error code appears only on a
certain screen, a memory address that
does not exist on the controller may be
set on the TS-series screen.
2) When the error code appears at
power-on, the memory address set for
buffering area or initial macro or in the
[Read/Write Area] tab window ([System
→
Setting] [Device Connection Setting])
may not exist in the controller.
Noise may cause the error.
2. Troubleshooting
Solution
1) Check if any address outside the
allowable range for controller memory is
set on the screen.
2) Check if the address set for buffering
area or initial macro or in the [Read/Write
Area] tab window ([System Setting]
[Device Connection Setting]) is outside
the allowable range for the controller
memory.
Check if appropriate measures are taken
against noise.
Example:
• Check if communication and power
cables are bundled together.
• Try to attach a ferrite core to the
communication cable.
• Try to attach a noise filter to the power
supply, etc.
