Actuator Sensor Interface (AS-i)

AS-i is an intelligent cabling system that is designed to replace the wires linking actuators and sensors with various controlling devices. We provide AS-i solutions, services, training, products and network diagnostic tools.

What is ASI?

Sensors and actuators have traditionally been connected to PLCs or other controllers via discrete wires and cable harnesses. AS-i offers users and integrators a reliable and cost-effective replacement for the bulky, time-consuming method of parallel wiring.

AS-i is a master-slave bus, with a single master controlling up to 62 slaves. It operates at the lowest level of the Fieldbus hierarchy, but when implemented with an AS-i master/gateway, it can connect to a higher-level network, such as DeviceNet, EtherNet/IP, PROFIBUS, etc.

AS-i Solutions and Services

Industrial ICT Solutions

We specialise in industrial applications, everything from process control systems, sensor technology, and systems engineering to custom development, data acquisition, logging, monitoring, and alerting.

Control Network Audits

Identify potential threats and discover inefficiencies in your infrastructure. We take a holistic view of your network and provide suggestions for improving your network performance.

Control Network Call Outs

System failures, connectivity issues, and network latency can disrupt performance and throughput, costing you more resources. We provide standard and emergency call-out services.

AS-i Training


Actuator Sensor-Interface (AS-i)

This course provides you with both theoretical and practical knowledge of AS-i, the gateways to PROFIBUS and PROFINET and provides the fundamental Fieldbus knowledge on AS-i.

Network Assurance

We will ensure your network is up and running quickly, safely, and efficiently to minimise disruption to your environment. We also carry out testing to ensure our installed solution meets the specification.

Our expertise lies in establishing, maintaining, and leveraging plant data for business benefit. Through our innovative solutions, we work alongside you to streamline processes, enhance efficiency, and reduce costly downtime.
