The next generation of flexible, configurable I/O for process automation systems has been one of the hottest discussion topics in the DCS world and is becoming the industry standard. Several suppliers have released DCS I/O solutions designed to overcome issues associated with late project changes and address the need for greater flexibility and configurability. A potential blueprint is Yokogawa’s and Klippon Engineering’s remote I/O solution.
Yokogawa's N-I/O brings a new level of modularity and flexibility and is also less error prone and altogether more resource efficient than conventional solutions by saving cables and space. Supported by Klippon Engineering's years of experience and knowledge in the process industry, this results in an ex-certified engineered solution that can be used even under harsh conditions of a process plant.
Most of today's popular configurable I/O systems focus on one of two approaches: hardware-based flexibility or software-based configurability. Hardware-based flexibility involves a plug-in module that plugs into a rack to characterise the signal type (AI, AO, DI, DO, etc.). The user can plug the module into any slot in the chassis. In this way, there are no restrictions on adding I/O points at later stages of the project. In addition, the user is not restricted by the limitations of the hardware.
The second approach, software-based configurability for different I/O points, offers similar advantages. However, instead of plugging in a characterisation module, the user configures the point in software to take into account the specific input or output channels.
Yokogawa's N-IO approach combines elements of both approaches. N-IO has an I/O module that can handle up to 16 I/O points and is software configurable, allowing the end user to select AI, AO, DI or DO for each point. Dedicated hardware-based plug-in adapters can be added for specialised inputs such as pulse and relay I/O. N-IO also takes into account the intrinsically safe design required in EMEA, Japan and Asia, among others
N-IO offers numerous advantages: it can help reduce projects by decreasing the amount of time needed to implement the physical part of the process control system. A system with configurable I/O allows flexible "binding," in which the software configuration of the system can be loaded into the physical system at a late stage in the project. Also referred to as "late binding," flexible binding allows integration to the control system without having to connect to the actual field control stations. As a result, binding can occur at the FAT or even SAT project stages. Flexible binding also provides potential cost savings related to installing, commissioning, and checking out field devices using the fieldmate validator.
The modularity offers the chance to create a blueprint for future expansion of the production, other process units on the plant or other plants within the industry. For reasons of protection, the electronics can be shipped separately from the enclosures and installed on site. Furthermore, the concept of I/O in the field is guaranteeing much less wiring to the devices which in turn reduces costs but also saves space in the control room. As a final point the communication cables are FO based. In other words, there is less error prone during installation and due to surges.
When used in the process industry, it must be considered that the environmental conditions are harsh and hazardous. This results in the challenge of protecting the expensive electronic components in the field. At the same time good accessibility to the electronics, for example for maintenance, must be ensured.
To meet these requirements, Klippon Engineering, as the leading expert for ex certified solutions in the process industry, is the partner of choice. Under the umbrella certification process, which includes IECEx, Ex and cULus approvals, it is possible to make the integration of different products flexible, fast, and feasible without any problems. For this purpose, the accredited Weidmüller-owned laboratory is utilized, equipped with 8 global locations, 70 employees, spanning approximately 3500 square meters.
Different sizes and different designs of Weidmüller Kippon® TB stainless steel enclosures offer a flexible solution for each application fulfilling customer needs. In the design, the enclosures can have a separate compartment for the electronics and the connectivity of the field wiring. During installation, fault-finding and during operation, there is no direct need to open the electronic compartment. Having a separate compartment for the field wiring ensures the protection of the expensive electronic components at all times.
Since Klippon Engineering is a brand of the Weidmüller Group, it can draw on an extensive portfolio of Weidmüller products, but also third-party products have been included. For example, the Weidmüller power supplies, terminal blocks, switches meet the requirements for such application in hazardous areas. Using CFD (computational fluid dynamics) for the electronic design enables consideration of balanced heat dissipation within the enclosure, relative to environmental and operating temperatures of the components used.
Early involvement was key to a successful design. Additionally, a strong focus on feasibility from the beginning avoids surprises during the project execution for this cooperation.
