[DESIGN PRECAUTIONS]
WARNING
● Make sure to set up the following safety circuits outside the programmable controller to ensure safe
system operation even during external power supply problems or programmable controller failure.
Otherwise, malfunctions may cause serious accidents.
- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock
circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit to
prevent damage (to the equipment at the upper and lower positioning limits).
- Note that when the CPU module detects an error, such as a watchdog timer error, during
selfdiagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU
module occurs in an input/output control block, output control may be disabled. External circuits
and mechanisms should be designed to ensure safe machinery operation in such a case.
- Note that when an error occurs in a relay, transistor or triac of an output circuit, the output might
stay on or off. For output signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machinery operation in such a case.
● In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
● For the operating status of each station after a communication failure of the network, refer to relevant
manuals for the network. Incorrect output or malfunction may result in an accident.
● Construct an interlock circuit in the program so that the whole system always operates on the safe
side before executing the control (for data change) of the programmable controller in operation.
Read the manual thoroughly and ensure complete safety before executing other controls (for program
change, parameter change, forcible output and operation status change) of the programmable
controller in operation.
Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.
● Especially, in the case of a control from an external device to a remote programmable controller,
immediate action cannot be taken for a problem on the programmable controller due to a
communication failure. Determine the handling method as a system when communication failure
occurs along with configuration of interlock circuit on a program, by considering the external
equipment and CPU module.

WARNING
● Do not write any data to the "system area" and "write-protect area" of the buffer memory in the
module. Executing data writing to the "system area" or "write protect area" may cause malfunction of
the programmable controller alarm. For the "system area" and "write-protect area", refer to Page
126 Buffer Memory.
● If a communication cable is disconnected, the network may be unstable, resulting in a communication
failure of multiple stations. Construct an interlock circuit in the program so that the system always
operates on the safe side even if communications fail. Incorrect output or malfunction may result in an
accident.
● To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.
[DESIGN PRECAUTIONS]
CAUTION
● Do not bundle the control lines or communication cables together with or lay them close to the main
circuit or power line. As a guideline, lay the control line and communication cables at least 100 mm
away from the main circuit or power line. Failure to do so may result in malfunction due to noise.
● When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on. Take
proper measures so that the flowing current does not exceed the value corresponding to the
maximum load specification of the resistance load.
● After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of the time.
● Simultaneously turn on and off the power supplies of the CPU module and extension modules.
● If a long-time power failure or an abnormal voltage drop occurs, the programmable controller stops,
and output is turned off. When the power supply is restored, it will automatically restart. (when the
RUN/STOP/RESET switch is on RUN side).

information
This function enables acquisition of diagnostic information and extended diagnostic information generated at DP-Slaves
during data exchange by using the buffer memory.
An error causes in the DP-Slaves can be checked with the diagnostic information and extended diagnostic information on the
FX5-DP-M.
(1) DP-Slave
Communications error occurs
The DP-Slave notifies the FX5-DP-M of diagnostic information.
Extended communications error occurs
The DP-Slave notifies the FX5-DP-M of extended diagnostic information.

Procedure for acquisition of diagnostic information/extended diagnostic information
The procedure for acquisition of diagnostic information and extended diagnostic information is as follows.
1. Check if diagnostic information is generated.
• BF LED turns on.
• 'Diagnostic information detection signal' (Un\G0.b1) turns on.
2. Check which DP-Slave sent the diagnostic information.
( Page 25 How to check DP-Slaves with communications errors)
3. Acquire the diagnostic information sent from the DP-Slave from the buffer memory of the FX5-DP-M.
( Page 25 Acquisition of diagnostic information)
4. Check whether that occurrence of extended diagnostic information has been notified from DP-Slave.
( Page 26 How to check if extended diagnostic occurs)
5. If the DP-Slave has extended diagnostic information stored in it, acquire the information from the DP-Slave.
( Page 26 Acquisition of extended diagnostic information from DP-Slaves)
6. Check the diagnostic information and extended diagnostic information for the error cause and take necessary action.
How to check DP-Slaves with communications errors
Diagnostic information detection status of DP-Slaves is stored in 'Slave status area (Diagnostic information detection)'
(Un\G23056 to Un\G23060).
For stations that sent diagnostic information, the relevant bit of 'Each station's diagnostic status' (Un\G23057 to Un\G23060)
is turned on.
Acquisition of diagnostic information
Acquire diagnostic information of DP-Slaves from the following buffer memory area. ( Page 144 Diagnostic information
area)
• 'Diagnostic information area' (Un\G23072 to Un\G23199)

Acquisition of extended diagnostic information
■How to check if extended diagnostic occurs
To check if extended diagnostic information is stored in DP-Slaves, check the status 1 information on DP-Slave stored in
'Diagnostic information area' (Un\G23072 to Un\G23199).
For the first DP-Slave, check b11 of 'Diagnostic information area (1st station)' (Un\G23073).
■Acquisition of extended diagnostic information from DP-Slaves
Acquire extended diagnostic information by the following procedure.
1. Write the FDL address for the DP-Slave from which to acquire extended diagnostic information to 'Extended diagnostic
information read request area' (Un\G23456). ( Page 146 Extended diagnostic information read request area)
2. Turn on 'Extended diagnostic information read request signal' (Un\G2.b6).
3. After reading the extended diagnostic information is complete, 'Extended diagnostic information read response signal'
(Un\G0.b6) turns on and the extended diagnostic information is stored in 'Extended diagnostic information read response
area' (Un\G23457 to Un\G23583).
4. After checking the acquired extended diagnostic information, turn off 'Extended diagnostic information read request
signal' (Un\G2.b6).
• The latest extended diagnostic information generated during data exchange is stored in the buffer memory
of the FX5-DP-M. To check the latest extended diagnostic information, acquire it from the following buffer
memory area.
'Extended diagnostic information area' (Un\G23328 to Un\G23454)
• For a program example of acquisition of extended diagnostic information, refer to the following.
