10.2 Error displays of the status LEDs, error messages
and rectification measures
This section lists and describes the most important error codes, possible causes and
potential rectification measures. These error messages can be displayed in the
Diagnostics view of the Setting and Monitoring Tool if you are connected to the
MELSEC-WS safety controller.
 For information on how to perform diagnostics see the Safety Controller Setting and
Monitoring Tool Operating Manual.
 Error displays for the individual modules and error elimination are described in the
sections on the individual modules, see Sections 3.5 to 3.10.

Possible reasons
Configuration in memory plug is
incompatible because it is for a
different CPU module type:
 Memory plug has been used before
in a system with different CPU
module type (e.g. WS0-CPU0
instead of WS0-CPU1 or vice
versa).
Wrong CPU module type is used in

the hardware installation.
Configuration in memory plug is
incompatible because it is for a newer
firmware version of the CPU module:
 Memory plug has been configured
for an incompatible higher CPU
module firmware version (e.g. V1.xx
instead of V2.xx).
 An older CPU module firmware
version is used in the hardware
installation.
Configuration in memory plug is
incompatible for at least one safety I/O
module:
 Safety I/O module is missing in the
hardware installation.
Configuration in memory plug is invalid:
The last configuration procedure

has not been completed
successfully, e.g. because the
power supply has been turned off
before writing to the memory plug
has been completed.
 Memory plug hardware failure.
 The memory plug is empty (out-of-
the-box value).
Possible measures
 Download a configuration with the
same CPU module type as in the
hardware installation.
 Replace the CPU module in the
hardware installation by a module
with the same module type as
selected in the project file.
 Download a configuration with the
same or a smaller CPU firmware
version (e.g. V1.xx instead of
V2.xx).
 Replace the CPU module in the
hardware installation by a module
with an equal or higher firmware
version selected in the project file.
 Download a configuration with a
matching list of safety I/O modules.
 Add missing safety I/O module in
the hardware installation.
 Download the configuration again
and ensure that the power supply at
the CPU module is on until the
download procedure has been
completed.
 Replace the memory plug and
download configuration again.
