4.8.2 Installing and uninstalling the module
Before installing or uninstalling the Ethernet module, make sure to read Section 4.1,
"Handling Precautions" thoroughly, ensure the safety of the installation, and handle
the module properly according to the instructions.
The following explains the procedures when installing/uninstalling the Ethernet
module.
<Operation procedure when replacing the Ethernet module>
(*1)
(Step 1) Read and save the parameters from the Ethernet module using
FX Configurator-EN-L
(*2)
(Step 2) Turn off the power supply to the base module, the extension device, and
the Ethernet module.
(Step 3) Remove the network cable and Ethernet module.
(Step 4) Set up and start up the new Ethernet module according to Section 4.2,
"Settings and Procedures Prior to Starting the Operation."
(*3)
(Step 5) Reset the external device.
(*4)
*1 It is recommended to record and save parameters not only when the Ethernet
module is replaced but also when parameters for the Ethernet module are
created or modified.
*2 When FX Configurator-EN-L is not installed :
1) Monitor the buffer memory in the Ethernet module using GX Developer, and
record set values of the parameters for the Ethernet module.
For details on the parameters, refer to Section 4.6 "Operational Settings",
Section 5.2 "Initial Processing", Section 5.3 "Router Relay Parameter" and
Section 5.5 "Open Settings".
2) After replacing Ethernet module, write the setting value into BFM by
GX Developer.
3) Write the setting value into the Flash ROM by BFM#25.
*3 When the Ethernet module is replaced, use the FX Configurator-EN-L to reset
the parameters.
*4 When the Ethernet module is replaced, reset the external device as well. (If the
external device retains the Ethernet address, it may be impossible to continue
communication because when a module is replaced the Ethernet address
changes.)
In the same way, when the external device (personal computer, etc.)is replaced,
restart the Ethernet module.
<Operation procedure when replacing the FX base module>
(Step 1) Turn off the power supply to the FX base module and the Ethernet
module.
(Step 2) Replace the FX base module. (See the Manual of FX base module.)
(Step 3) Turn on the power.
