The following data is not written as the protocol setting data so it will not be displayed even when read.
However, when the protocol is selected from the predefined protocol library, the following can be displayed.
• Manufacturer
• Packet Name
• Protocol Detailed Setting Type, Version, Explanation
• Packet Setting Configuration Element Name
After writing the protocol setting data, the setting data are enabled at the following timing.
• When the system is powered off and on
• When the CPU module is reset
• When the status of the CPU module changed from STOP to RUN state
The predefined protocol settings written in the SD memory card can be transferred to the CPU module memory by using boot
operation. For details on boot operation, refer to the following.

■When the protocol setting data are written into multiple target memories
When the protocol setting data are written into multiple target memories, the following operation will take place.
: The protocol setting data are written., : The predefined protocol data are not written.

By writing the protocol setting data to the CPU built-in memory, the same setting can be used even after
module change.
When capacity of the CPU built-in memory is insufficient, write data to an SD memory card.
Although the protocol setting data can also be written to the intelligent function module, the data must be
written again when the module is changed.

Operation
Operation follows settings in "Module Extended Parameter" under
"Setting of File/Data Use or Not in Memory Card" of the "Memory Card
Parameter" window.
As soon as the protocol setting data are enabled, the predefined protocol
settings of the RJ71EN71 or the RnENCPU (network part) are
overwritten by the predefined protocol settings in the CPU module or SD
memory card.
