All Industry 4.0 concepts have one thing in common: data and digital communication play a central role in this. Accordingly, machine and system components have to become more and more communicative. This also applies to sensors as an important component within machines and systems. Because Industry 4.0 concepts require seamless communication from the field level through the control, management and operations management level to the company level.

The problem: As a rule, a PLC processes the data of the connected sensors in a production machine, for example, but it is generally not intended to forward this data to the control level. If you want to implement such a forwarding, the PLC program must be changed. To avoid this, data from sensors that have an IO-Link interface can be forwarded directly to higher-level systems. This requires a tool that can process different data sources and can work with all common protocols. IFM provides such a tool with the linerecorder framework.

Software gateway enables bidirectional communication

The system consists of several software modules with which, according to the IFM, continuous communication can be implemented. The Linerecorder Agent Connectivity Port is, for example, a software gateway that is supposed to allow bidirectional communication between a large number of different interfaces. This enables communication between SAP systems on the one hand and the data of the devices from the field, control and management levels on the other.

A lot of sensor information, which is required for predictive maintenance or energy consumption measurement, is not necessary for the control tasks in the machine and is therefore not available in the PLC. For this reason, IFM has set up a second communication path. IFM describes this direct path of sensor data bypassing the control level as Y communication, since the data reaches the PLC once, as in the two arms of the letter Y, and on the other hand goes directly to the corporate management level.

Integrated visualization system

In the software framework, the Linerecorder Smartobserver also contains a visualization system with which the user should be able to easily monitor the condition of machines and systems, explains IFM. The visualization of the SmartObservers can be easily adapted according to user requirements.

The linerecorder framework makes many applications possible in which sensor data play a role: According to IFM, a typical example is the condition-based maintenance of machines. Sensors recorded vibrations that indicate the wear of a bearing inside the machine; Based on the sensor data, the replacement of the bearing can be planned in good time. Both machine downtimes due to sudden bearing damage and unnecessary maintenance work could be avoided.

Communication with higher-level systems

Another example: the monitoring of compressed air systems. For example, sensors that measure compressed air consumption are already available in many machines to ensure operation. The data from these sensors could be used to detect and correct compressed air leaks. However, this only works if the sensor data are available on a higher-level system, which is easily possible with the communication via the Y-way and the liner recorder framework, according to IFM.
