The new CPUs and Power Modules in the Remote I/O IS1+ system from R. STAHL are now also available for installation in Zone 1. This means that the extensive range of functions offered by the Zone 2 version, such as integrated support for PROFIBUS DP, PROFINET (CC-B), EtherNet/IP, Modbus TCP and OPC UA, can now also be used in Zone 1.

Although IS1+ has, until now, been restricted to eight I/O modules for Zone 1 installations, the new solution have now made it possible to double the number of I/O modules that can be connected to 16. This also makes the system even more cost-effective to operate. In plants with both Zone 1 and Zone 2 installations, in particular, the additional engineering work required is significantly reduced because Zone 1 and Zone 2 systems can be handled almost identically in terms of their design and planning.

Unlike the Zone 2 CPU, the Zone 1 version uses intrinsically safe communication interfaces in order to enable extensions, modifications or maintenance work during operation, even in explosive atmospheres – without any time-consuming approval processes or shut downs. The PROFIBUS DP connection is still based on the intrinsically safe RS485-IS standard. For the Ethernet protocols, IS1+ uses the new, standardised Ex i version for 4-wire Ethernet: 100BASE-TX-IS. In order to bypass the length restriction of 100 m for copper-based Ethernet, a Zone 1 media converter is in development, which converts the intrinsically safe 100BASE-TX-IS in FO 100BASE-FX for distances of up to 30 km. As well as the communication protocol, which can be adjusted by the user, all additional innovative functions of the Zone 2 version have been ported to the Zone 1 version; take, for instance, the expanded ambient temperature range of -40 to +75 °C in both horizontal and vertical mounting positions. Also included is integration into ring topologies with MRP or DLR, as well as support for a range of redundancy concepts like CPU & Power Module redundancy or PROFINET S2 (Conformance Class B).

The comprehensive diagnostics, including NE107 "Maintenance Required" signalling for predictive maintenance, are accessible for both the CPU and Power Module. All diagnostics and system information plus HART-field device data is available as a second channel via the process bus or Ethernet network, as well as via a separate ServiceBus. Access can be obtained via the typical FDT/DTM means or via the optional, integrated OPC UA interface.

In an increasingly digital and interconnected world, it is imperative for the network infrastructure to seamlessly integrate and interact with various components such as stationary devices, software, and mobile devices. It is equally vital to safeguard your operations against cybersecurity risks and ensure the safety and well-being of your employees in potentially hazardous environments. This is where R. STAHL steps in as a provider of secure communication solutions, specially designed for hazardous areas.

Ethernet Advanced Physical Layer (Ethernet-APL) is the new 2-wire solution for Ethernet, based on IEEE and IEC standards. This allows you to digitalise your process facilities from the devices in the field all the way to the control room. The new technology is also making inroads into explosive atmospheres: Ethernet-APL supports the type of protection intrinsic safety "i" and thus enables Ethernet access in hazardous areas up to Zone 0.

Another advantage of digitalisation lies in the extensive possibilities for process monitoring and diagnostics. This optimises the availability of your equipment. Reach out to us! We bring Ethernet-APL to your process facilities. Since we are one of the partners developing this new technology, you benefit from our know-how first hand. You can rely on our expertise – from consulting to commissioning and beyond.

The field switch is a central component in the Ethernet-APL network of your process facility. R. STAHL offers particularly robust and durable field switches for the new technology, which are characterised by two key advantages: The R. STAHL Ethernet-APL field switch supports the
operation of intrinsically safe devices in the field and, depending on the version, it can be used in the explosive atmospheres of Zones 1 and 2. Thanks to their fault diagnostics and status messages, they provide extensive support for commissioning and network troubleshooting.

The main functions and features of the R. STAHL Ethernet-APL field switch:
• Distribution and coupling of data streams in the network.
• Power supply of the connected field devices with intrinsically safe auxiliary power.
• Installation directly on site in the field in Zone 1 or 2 due to robust design.
• Diagnostic functions: Fault diagnosis, status messages, operating notes.
• Optional use with fibre optic cable to bridge distances of several kilometres (Zone 2 versions only).
• Optional use with PROFIBUS PA devices through integrated PA proxy.
