This allows the user to monitor any drift and anticipate any potential anomalies. The Ethernet module load is indicated in one of three ways: b Expected load in the Unity Pro configuration screen b Actual load in the Unity Pro diagnostics/debug screen b In the SNMP interface for access by the SNMP network manager The bandwidth is shown as a percentage for each of the following services: b Modbus messaging b I/O Scanning b Others Ethernet solutions with Modicon M580 platforms Modicon M580 platforms feature 2 types of connection to the Ethernet network: b The 10/100BASE-TX port integrated in the CPUs, which also process the application and exchange data with the other modules supported by the rack and other communication ports (CANopen bus, Modbus serial link, etc) b The multiple 10/100BASE-TX port in dedicated Ethernet modules on which, unlike the CPU with integrated Ethernet port, all the resources are allocated to Ethernet Modbus/TCP and EtherNet/IP communication These fundamentally different hardware characteristics result in equally different capacities in terms of services and performance: b The integrated port is a low-cost way of satisfying applications that are not too demanding in terms of communication ( y 500 user messages/s). b Where there are a large number of exchanges, use of a dedicated Ethernet network module is strongly recommended to help improve the performance.
