■Writing protocol setting data
Write data of the protocol settings to a CPU module or C24.
[Online]  [Module Write]
Write the protocol setting data after selecting the module to be written and memory.
When writing data to the CPU module, the protocol setting data is written to "Module Extended Parameter".
The following data is not displayed even when reading from CPU module because it will not be written as a
protocol setting data. However, the protocol selected from the predefined library is displayed.
• Manufacturer
• Packet name
• Type, Version, Explanation in the protocol detailed setting
• Element name in the packet setting
The operation when the predefined protocol setting is written to a multiple target memory is as follows:
● When the predefined protocol setting is written to both CPU built-in memory and an SD memory card
The CPU module operates according to the settings of "Memory Card Parameter". For details on the "Memory Card
Parameter", refer to the following manual.
 MELSEC iQ-R CPU Module User's Manual (Application)
● When the predefined protocol setting is written to a CPU built-in memory or an SD memory card, and C24
The predefined protocol settings of the CPU built-in memory or SD memory card is enabled in the following timing. (If the
predefined protocol settings are written both CPU built-in memory and SD memory card, the CPU module operates according
to the settings of "Memory Card Parameter".
When the predefined protocol is enabled, the predefined protocol settings of C24 will be overwritten with the predefined
protocol of CPU built -in memory or SD memory card.
• When the power is turned OFFON
• When the CPU module is reset
• When the CPU module is switched STOPRUN
Setting method
Set the predefined protocol settings in "Various control specification" of "Basic Settings". (Page 422 PARAMETER
