8 DATA COMMUNICATION USING THE PRE-DEFINED PROTOCOL
8 DATA COMMUNICATION USING THE PRE-DEFINED PROTOCOL
Data can be transferred between the QJ71C24N(-R2/R4) and an external device using
GX Configurator-SC (Pre-defined protocol support function) with a protocol appropriate
to the external device.
Protocols can be selected from the pre-defined protocol library offered or can be
created and edited arbitrarily.
Since registered setting data are written to a flash ROM, the program volume in a
programmable controller CPU can be reduced.
