File transfer function (FTP server)
Perform file writing with the file transfer function (FTP server) as follows.
1.
Log into the Ethernet-equipped modules of both systems.
2.
Perform remote STOP on the CPU modules of both systems.
3.
Write the file to the CPU modules of both systems.
4.
Perform remote RUN on the CPU modules of both systems.
5.
Log out from the Ethernet-equipped modules of both systems.
6.
Clear the errors from the standby system CPU module.
*1 When the status of the control system CPU module is STOP state, a continuation error occurs in the standby system CPU module.
*2 When the parameter file has been written, the CPU modules must be reset.
*3 When the status of the control system CPU module changed from STOP to RUN state, check the error status of the standby system
CPU module, and if an error has occurred, turn on 'Error reset' (SM50) to clear the error.
Time setting function (SNTP client)
When the time is set by a program, an error may occur if system switching occurs in the timing in which the program is
executed. If an error occurs, execute the program after system switching.
IP filter function
When using an IP filter, exclude the control system IP address, system A IP address, and system B IP address from the IP
filter settings. Otherwise, operation may not be performed normally.
IP address change function
Do not use the IP address change function to change IP addresses in a redundant system. Normal communication is not
possible if an IP address has been changed. When the IP address is changed using the IP address change function, clear the
IP address storage area.
Communications with Different Networks
Precautions exist for communications with different networks via a redundant system. ( Page 387 When the networks
contain a redundant system)
