● CPU device
When a CPU device is specified as the data storage area, the Q series C24N/L series C24 module performs the
read/write CPU device process.
If the total length of variables used in a packet exceeds 1920 bytes, 'read CPU device process'/'write CPU device
process' of the Q series C24N/L series C24 module needs to be performed more than once, and the processing
time might be longer.
● Intelligent function module device (buffer memory)
High-speed protocol processing is available because a Intelligent function module device (buffer memory) is not
affected by the sequence scan of a programmable controller CPU.
● Execution of a protocol including a Non-conversion Variable or Conversion Variable
When executing a protocol including a Non-conversion Variable or Conversion Variable, do not change the value
of a CPU device specified as a variable during execution of the dedicated instruction.
