PERMANENT AVAILABILITY OF REALTIME ASSET INFORMATION MOBILE offers improved flexibility and increased employee productivity

Digital, mobile, networked and standardized solutions are providing new connectivity for process control users to communicate via HART, FOUNDATION Fieldbus and Profibus PA. The result is that machine and field device data are more available to improve and rationalize processes for configuration and troubleshooting.


Mobile-based asset management tools enable maintenance personnel to manage the entire field device lifecycle on site and configure devices using standardized integration technologies. MOBILE offers a range of mobile communication devices, such as the smartphone of the series IS520 or the tablet of the series IS910. Both devices have an Android operating system. Depending on the field of application they are available as IECEx Zone 1, IECEx Zone 2 or none Ex‑device.

By linking up via mobiLink the IS520 or the IS910 with the whole system, the data are available anytime, anywhere. Such complete solutions are supplemented by interfaces which enable mobile access to field devices via the corresponding integration technologies and protocols on site.

Fast, simple device replacement with the lowest possible downtime

Field devices are replaced before they break as part of the predictive maintenance strategy. But before maintenance personnel visit the plant, the replacement device is preconfigured on the workbench. The networked smartphone IS520 and the tablet IS910 are also used here in conjunction with the mobiLink interface in order to enable a fast, simple device replacement with the lowest possible downtime.

Offline configuration in absence of the device

The devices can also be configured offline in advance without the need for the device to be physically present. Parameters are saved in the application based on the description files for the integration technologies, and these are loaded when the device is implemented, which saves time and effort.

Increase employee productivity

An interconnected, compatible solution portfolio of the MOBILE communication devices, mobile interfaces like mobiLink and professional applications enables technicians on site to monitor and control processes in detail, contributes to more flexibility and helps to increase employee productivity. With mobile solutions, information on assets across the entire process chain is permanently available in real time. People, processes and systems are thus networked as required for Industry 4.0.


Interfaces between the above-mentioned mobile end devices and field devices have highly specific requirements. Depending on the use case and end device used, the interface should be compatible with different technologies. Often, however, the interfaces available only cover a defined requirement and cannot be used flexibly for different use scenarios in often complex plants. Maintenance staff is frequently forced to use several different interfaces in order to perform the varied tasks at the plant.

Multiprotocol solution 'mobiLink'

Softing offers users looking for a multiprotocol solution its mobile interface 'mobiLink', which via a single interface provides access to the three most important communication protocols in process automation: HART, FOUNDATION Fieldbus and Profibus PA. The link to the MOBILE devices is via Bluetooth. The scope of delivery includes drivers to connect field devices via FDT/DTM (Field Device Tool, Device Type Manager) and FDI (Field Device Integration) technology. The additionally included DevComDroid app by ProComSol, a provider of communication solutions for the HART market headquartered in the USA, even makes it possible to easily and intuitively configure field devices via EDD (Electronical Device Descriptions). The mobiLink technology scans the bus automatically, reports the devices found including device status and underlying device parameters and opens the right device description file. From there, the user can intuitively navigate to the device detail, such as diagnostics, state monitoring, parameterization and configuration. Users who require interfaces for several protocols save costs when using mobiLink, because they only need one interface. In addition, the use of only one interface results in a significant work reduction when implementing and maintaining field devices.


The ATEX-certified solution from MOBILE and Softing is suitable for use in potentially explosive atmospheres due to its explosion risk approval for Zone 1, its robust design and the option to connect to intrinsically safe circuits.
