About us
Overview
Quantum communication and networking modules use a variety of different techniques to interface to the Quantum controller over the local rack.
Direct CPU Driver
This technique allows the CPU to control high speed data transfers to and from the communication and networking modules, maximizing throughput and performance.
This technique is used extensively by the Remote I/O network and Hot Standby system to provide a highly deterministic synchronization of the CPU and I/O scans.
NOTE: Only one Remote I/O Head Interface is supported for each Quantum CPU.
Option Module Interface
This technique allows the communication and networking modules to control data transfers to and from the CPU, maximizing the flexibility of the communications interface.
This technique is used extensively by the Modbus Plus and Ethernet peer-to-peer network modules. The number of option module interfaces supported by each CPU model is described in the following table.
