[Calculation example]
Estimate the time required to process the Input instruction when receiving 100 bytes of data using the non procedure protocol with the QJ71C24N. (Unit: ms)
• Scan time : 10 ms
10 + 0.09 
100 + 7.0 
26.00 (ms)
2 When only using CH1 of the Q series C24 and when processing only 30 bytes of data received, the time until the reception data read request (X3) comes on is displayed after the Q series C24 receives data from the network.
