PORT1
Procedure
1. Turn the PLC off and set the baud rate using the DIPSW.
2. Turn the power on and check the value set for “ Special internal output: WRF01A”.
3. When the transmission control protocol has correctly been selected, setting is completed. If it is wrong, set a correct
value.
4. Set the bit “R7F6” (setting write request) to save the setting in the flash memory.
* It is not necessary to make the setting again upon next power-up once the setting has been saved in the flash memory.
Note that the ladder tool cannot be connected when the setting has been saved using the transmission control protocol
2.

PORT2
Procedure
1. Check the value set for special internal output “WRF03D”.
2. When the setting, such as transmission control protocol or baud rate, has correctly been defined, the setting is
completed. If it is wrong, set a correct value. See “User Setting” described in “ Special internal output: WRF03D”.
3. Check that the value set for WRF03D has been changed to the one shown in the “System Setting” column.
4. Set the bit “R7F6” (setting write request) to save the setting in the flash memory.
* It is not necessary to make the setting again upon next power-up once the setting has been saved in the flash memory.
