Data transmission in industrial environments and network management requires the use of high-performance managed switches capable of handling protocols in multi-layer network architectures for layer 2 access, layer 3 routing with advanced diagnostics (port diagnostic, packet diagnostic…) and redundancy and security functions (IEEE 802.1X, Broadcast/Multicast/Unicast).
Standard protocols handled are Ethernet TCP/IP, Modbus, VRRP, RSTP, HTTPS, TFTP, SNMP, BOOTP, GMRP, DCP, LLDP, IGMP (Snooping/Querier)
The physical supports of the networks are made of copper or fiber, single-mode or multi-mode with star or ring structures.
The integration of machines in systems distributed over large surfaces requires their physical connection and data transmission via wired networks or WIFI connections for self-propelled elements. The use of communication standards such as Ethernet TCP/IP and Profinet is essential to guarantee the maintainability and management of the systems.
The choice of communication network structures, switches and components for communication and remote assistance are crucial elements for the continuity of operation of the automatic systems and for their integration into corporate structures developed in accordance with Industry 4.0 criteria.
Connectivity of components for communication
The communication between SCADA supervision system, PLC, Robot, Data Matrix optical reading systems, Labeling Systems is obtained using industrial networks with structures on different levels with star or ring architectures.
Architecture and levels of industrial networks
The automation of lines with P.L.C. with distributed intelligence architectures requires the use of high-performance industrial data networks, designed on multiple levels and with high-speed switches to ensure the supervision and management of I/O signals, sensors, actuators, measurements, synchronizations, exchange real-time data. Often within the same networks it is necessary to integrate intelligent instrumentation with Ethernet, Modbus, RS 485 communication protocols.
Management of industrial data networks in real time
The use of power components with communication capabilities, such as inverters, drives for brushless motors, axes, connected to the network and interfaced to the P.L.C. makes it possible to remotely program and diagnose these devices, as well as manage and parameterize them according to recipe.
Programming and diagnostics of power equipment within networks
