Check procedure
Cannot write data to the remote
register RWw of a remote
device station.
Is the corresponding remote device station
performing data link?
• Check the LED displays on the corresponding
remote device station.
• Check the communication status of the master
station with other stations (SW0080 to SW0083).
Is data read from the correct address of the
remote register RWw (buffer memory)?
Check the user program.
Is the correct master station’s parameter
information area (CPU internal parameters, default
parameters) being used?
Check the parameter information (SW0067).
Is the corresponding remote device station
number recognized by the master station?
• Check the parameters.
• Check the total number of stations (SW0070).
• Check the maximum communication station
number (SW0071).
• Check the number of connected modules
(SW0072).
Is the corresponding station set as a reserved
station?
• Check the parameters.
• Check the reserved station designation status
(SW0074 to SW0077).
Are there any duplicate station numbers?
• Check the station number setting.
• Check the installation status (SW0069).
• Check the station number duplicate status
(SW0098 to SW009B).
Do the settings match?
• Check the installation status (SW0069).
• Check the station number duplicate status
(SW0098 to SW009B).
• Check the installation/parameter matching status
(SW009C to SW009F).
Is the remote device station initialization procedure
registration being executed?
Check if the remote device station initialization
procedure registration instruction (SB000D) is on.
Cannot communicate from the
master station (remote output
RY) to a local station
(remote input RX).
Is the corresponding local station performing data
link?
• Check the LED displays on the corresponding
local station.
• Check the communication status of the master
station with other stations (SW0080 to SW0083).
Is data written to the correct address of the remote
output RY (buffer memory) of the master station?
Check the user program.
Is data read from the correct address of the
remote input RX (buffer memory) of the local
station?
Check the user program.
Is the corresponding local station number
recognized by the master station?
• Check the parameters.
• Check the total number of stations (SW0070).
• Check the maximum communication station
number (SW0071).
• Check the number of connected modules
(SW0072).
Is the corresponding station set as a reserved
station?
• Check the parameters.
• Check the reserved station designation status
(SW0074 to SW0077).
Are there any duplicate station numbers?
• Check the station number setting.
• Check the installation status (SW0069).
• Check the station number duplicate status
(SW0098 to SW009B).
Do the settings match?
• Check the installation status (SW0069).
• Check the station number duplicate status
(SW0098 to SW009B).
• Check the installation/parameter matching status
(SW009C to SW009F).
