4.2 Settings and Procedures Prior to Starting the Operation
The following shows a flow of the procedure that is required prior to operating:
POINT
(1) When the parameter settings are added or modified using the
FX Configurator-EN, the settings differs depending on the connection
condition to the Ethernet module as shown below.
When directly connected to the PLC
After the parameter settings are added or modified, re-initialization
processing can be automatically performed.
When connected via Ethernet
The added or modified parameter settings are not reflected.
To operate the Ethernet module after the parameter settings are added or
modified with FX Configurator-EN, first save the parameter values, second
reboot the Ethernet's module power.
(2) Timing for powering ON
Power ON the PLC and the Ethernet module with the timing as shown below.
When turning the system power ON:
Turn the power of the Ethernet module ON first, and then turn ON the
power of the PLC after that when different power source is used for the
PLC and Ethernet module.
It is possible to supply power to the Ethernet module from the 24 VDC
service power supply of the PLC. (Pay attention to the current capacity of
the service power supply of the PLC.)
When turning the system power OFF:
Turn the power of the PLC and Ethernet module OFF at the same time.
Or turn OFF the power of the PLC first, and then turn OFF the power of the
Ethernet module after that.
