This chapter describes the parameter settings required for communications between the RJ71CN91 and other nodes.
2.1

Setting Parameters

When used in the CANopen 405 mode
The following is the procedure for setting parameters when the RJ71CN91 is used in the CANopen 405 mode.
1.
Add the RJ71CN91 in the engineering tool.
[Navigation window]  [Parameter]  [Module Information]  Right-click  [Add New Module]
2.
Basic Setting and Refresh Setting are available for module parameter setting, which can be selected from the tree in the
following window.
[Navigation window]  [Parameter]  [Module Information]  [RJ71CN91]  [Module Parameter]
3.
Start CANopen Configuration Tool to configure CANopen.
4.
Write the CANopen setting to the CPU module from CANopen Configuration Tool. ( Page 112 Writing the settings)
5.
Write the module parameters to the CPU module using the engineering tool.
[Online]  [Write to PLC]
6.
The settings are reflected by resetting the CPU module or powering off and on the system.
When used in the Layer 2 message mode
The following is the procedure for setting parameters when the RJ71CN91 is used in the 11-bit CAN-ID Layer 2 message
mode or 29-bit CAN-ID Layer 2 message mode.
1.
Add a general-purpose intelligent module (for single slot) in the engineering tool.
[Navigation window]  [Parameter]  [Module Information]  Right-click  [Add New Module]
2.
Set the number of occupied points for the general-purpose intelligent module (for single slot) to 32 points.
[Navigation window]  [Parameter]  [Module Information]  [Gen. Intelligent Module (1 slot)]  Right-click 

3.
Set the function mode to the buffer memory.

4.
Save the buffer memory settings to the flash ROM.
Set 'Save/restore configuration' (Un\G22), then turn on 'Configuration save/factory default configuration restore request'
(Y1F), and write the buffer memory setting to the flash ROM.
Page 153 Configuration save/factory default configuration restore completed/request (X1F)/(Y1F)
Page 158 Save/restore configuration (Un\G22)
5.
Restart the RJ71CN91 to apply the function mode. (Perform steps 3 to 5 only to change the mode.)
Page 149 Module restart completed (X2), Module restart request (Y2)
6.
Set the other parameters of the buffer memory.
Page 159 Baud rate (Un\G24)
Page 176 Pre-defined Layer 2 message configuration (Un\G6000 to Un\G6167)
Page 183 CPU module STOP transition message (Un\G8450 to Un\G8477)
Page 184 Receive/Transmit process data (Un\G10000 to Un\G10293)
Save the above items to the flash ROM if needed. Restart of the RJ71CN91 is not required.
7.
Set the RJ71CN91 to the online mode using 'Layer 2 online mode request' (Y3) and apply the parameters.
