INSUM - System Overview

Site-Wide Ethernet LAN Dual-Redundant
Multi-master Dual redundancy
With four Gateways connectable to one INSUM COMMUNICATIONS UNIT the INSUM system offers multi-master capabilities as an integral part of the design.
Two ICUs configured in one system
paired with peer-to-peer communications at the field level provide an inherently simple method for dual-redundant communications down to the field device.

Connectivity and Communication
Connections in operation to many, many control systems

Gateways for different protocols can be operated simultaneously within the system. Interfaces to virtually any manufacturer's control system have already been realized. These Gateways also provide connection and data filters for communication of essential information to higher level systems.

Communication Philosophies
Most protocols operate in master-slave mode, where the master controls communication on the bus and cyclically exchanges information with every slave device (bus polling). In most applications the PCS assumes the role of the master.

Peer-to-peer or master-master communications allow exchange of data between devices on an equal rights basis. Field devices and control systems communicate event-driven, leading to shorter response times. INSUM utilizes this form of communication.

The system response time, consisting of a command received at the ICU, transmission to the field device, command execution and response back for collection is typically less than 200 ms.
