Appendix 1 Module Label
The I/O signals and buffer memory of the Ethernet-equipped module can be set using module label.
Structure of the module label
The module label name is defined with the following structure.
"Instance name"_"Module number"."Port number"."Label name"
"Instance name"_"Module number"."Label name"
"Instance name"_"Module number"."Port number"."Label name"_D
"Instance name"_"Module number"."Label name"_D
EN71_EE_1.stPort1.wnVal_IP_Address_D[0]
■Instance name
The following are the instance names of the RJ71EN71 and the RnENCPU (network part) corresponding to each network type
setting.
■Module number
A sequential number starting with "1" for identifying a module from the one with the same instance name.
■Port number
The port number is added to the module labels corresponding the buffer memory areas other than P1/P2 common area.
The following lists the characters corresponding to the port numbers
■Label name
A label name unique to the module.
■_D
This symbol indicates that the module label is for direct access. The label without "_D" is for refresh. The following are the
differences between refresh and direct access.

Type Description Access timing
Refresh The values read/written from/to the module labels are reflected to the module at refresh. The
execution time of the program can be shortened.
At refresh
Direct access The values read/written from/to the module labels are reflected to the module immediately.
Although the execution time of the program is longer than the one at refresh, the responsiveness is
improved.
