    What is the total number of Modbus TCP/IP messages that can be processed by the Quantum PLC's each scan (cycle)?

    The following table shows the total number of Modbus TCP/IP messages that can be processed by the Quantum PLC's
    each scan per the number of communication (NOE) modules in the system.


    msg/cycle: number of messages being received per cycle from the PLC master task (typical cycle from 50 to 100 ms).

    (1) Only if using Unity Pro software. If using PW or Concept then:
    All Comm requests = 1 msg/cycle
    Additional 4x = 4 msg/cycle
    Ethernet Modules per PLC still = 6, however only 2 are looked at per PLC scan.

    For Example if you had a 140CPU43412 with 4 140NOE77101's programmed with Unity Pro then the total number of msg/cycle is:
    For All types of Communication
    4 x 4 msg/cycle = 16 msg/cycle
    For read/write 4x registers
    4 x 8 msg/cycle = 32 msg/cycle
