The planning and implementation effort required for an Ethernet APL solution is drastically reduced compared to Local I/O. There are three main advantages of Ethernet APL:

• Increased data rates for communication with field devices
• Significantly reduced effort required for the initial parameterisation of field devices during commissioning
• Software-assisted loop check instead of manual procedures involving numerous individual steps to verify measurement ranges and correct configuration
• Integrated engineering of the NOA secondary channel.
• Access to all data from the field instead of selected values, as is the case with current implementations

Ethernet-APL is key to the digitalisation of process automation during the operational phase. Compared to Remote I/O and 4–20 mA, it offers direct digital communication with field devices and infrastructure components. This makes Ethernet-APL a crucial next step towards improving productivity, quality and efficiency in operations.

Ethernet APL supports and simplifies the operational process

• Ethernet APL systems provide seamless access to field data
• Real-time diagnostics and fault detection for field devices and network infrastructure
• Automated functional and loop tests are possible
• Precise data enables predictive maintenance strategies
• A standardised system infrastructure simplifies stock management and staff training.
• Easy conversion from non-safety-critical to safety-critical circuits.

Ethernet APL improves the efficiency of maintenance work and facilitates a centralised approach to asset management and diagnostics, for example by providing real-time, up-to-date documentation of the plant’s network structure.

The potential benefits of Ethernet APL are:

• Simpler and faster device replacement
• Faster device configuration and diagnostics
• Instant live network layout, automatic comparison of planned and actual states
• Centralised and faster device updates
• Improved network commissioning, maintenance and troubleshooting

Ethernet APL technology enables the transmission of multiple measurement values and parameters per device with a high degree of accuracy.

This opens up new possibilities in the field of signal analysis:

• Reduction in the amount of cabling required per device
• Collection of complex data: FFT for vibration-generating equipment, precise fault identification
• Use of AI algorithms for pattern recognition and prediction of potential failures
• AI analyses to improve operations, increase efficiency and reduce costs
