The latest generation of explosion-protected remote I/O systems from R. STAHL, IS1+ for installation in zone 1 and zone 2 or Division 1 or Division 2, enables fast communication via Foundation Fieldbus High Speed Ethernet (FF HSE). As the first product in its class, IS1+ has been acknowledged with the official "tick mark" for a FF HSE device following testing and registration by the FieldComm group. Featuring a transmission rate of up to 100 Mbit/s, the HSE standard has been designed by the Fieldbus Foundation – now a member of the FieldComm Group – especially with remote I/O, wireless gateways, and similar applications in mind. FF HSE has more recently been further augmented by F-ROM (Foundation for Remote Operations Management) technology.
F-ROM features a number of enhancements, which are all also supported by IS1+. These include special "RIO Function Blocks" for an effective transmission of large amounts of data, "Association Blocks" for comfortable offline configuration as, and special "HART Transducer Blocks", which – for the first time ever – enable an integration of HART field devices into FF architectures.
Remote I/O solutions with F-ROM technology are ideally suited to supplement fieldbus installations with smart H1 field devices. Using F-ROM-enabled remote I/Os, conventional and HART field devices can be integrated into fieldbus installations alongside H1 devices. As a result, the installation effort is significantly reduced. In addition to FF HSE and F-ROM, IS1+ supports other Ethernet-based protocols such as Modbus TCP, EtherNet/IP and PROFINET for cutting-edge, fast communication in process plants with hazardous areas.
Users also continue to benefit from the general advantages of the IS1+ system, namely hot-swapping capabilities for all modules in Zone 1 and Division 1, multi-functional I/O modules and preventive maintenance messages according to NE107. Moreover, R. STAHL offers a standard warranty extension for three years free of charge on all IS1+ systems.
