Corrective Action
Ensure that the program version is ***.QPG and
the file contents are programs.
Create a program with GX Developer or PX
Developer specifying the redundant CPU
(Q12PRH/Q25PRH) as the PLC type, and write it
to the CPU module.
• Check program configuration.
• Check parameters and program configuration.
• Check program configuration.
• Check parameters and program configuration.
Reduce the SFC programs to one.
Check for illegal accesses. If any illegal access is
identified, take actions such as disabling
communication of the connection.
If it was identified not illegal, clear the error and
perform the following. (Clearing the error also
clears the remote password mismatch counts.)
• Check if the remote password sent is correct.
• Check if the remote password has been locked.
• Check if concurrent access was made from
multiple devices to one connection by UDP.
• Check if the upper limit of the remote password
mismatch count is too low.
• Check if the time setting function is set up
correctly.
• Check if the specified SNTP server is operating
normally, or if any failure has occurred on the
network connected to the specified SNTP
server computer.
