The IO4 is an advanced hardware device designed to efficiently query information from a wide range of equipment controllers, typically using serial communication. It directly queries internal controller addresses for the equipment status and faults, providing a replica of data available to the PLC. This solution is most desirable when a facility has many identical controllers.
Highlights:
Robust data collection and fault logging through serial communication with the equipment controller. This solution does need to be integrated with the target controller and benefits from scale once that interface is configured
Extensive alerting and fault logging - tracks what the controller sees including fault codes
Analysis delivers cross-portfolio insights
May require custom engineering depending on user data requirements and portfolio
IO4 deviceUtilizing robust RS-232, RS-422, RS-485, or Ethernet interfaces, the device ensures reliable and accurate data collection from industrial control systems, PLCs, and other equipment controllers. With its high-speed polling capabilities and a flexible configuration system, the IO4 seamlessly integrates into existing networks, optimizing monitoring and control operations in diverse industrial environments.
Like all Knaq devices, the IO4 is equipped with on-board cellular connection, allowing direct communication with the cloud from anywhere–regardless of whether network access is available. There is also ethernet and WiFi connectivity available.

IO2 deviceThe Knaq IO1/IO2 is our in-house designed OEM-agnostic, non-invasive solution. The Knaq hardware utilizes non-invasive sensors for data acquisition, remaining electrically isolated from the monitored equipment. Each Knaq device monitors controller I/O in a 1:1 relationship and produces standardized readouts across equipment types and manufacturers. In this manner, data granularity is preserved without sacrificing universality.
Data analysis occurs at both the edge and in the cloud, with machine learning algorithms running continuously on incoming inputs. Real-time data, historical trends, and multiple forms of alerts are displayed on the user dashboard, exportable reports, email summaries, and SMS texts. Equipment performance with millisecond accuracy can easily be accessed from any internet- connected device, anytime, anywhere.
Like all Knaq devices, the IO1/IO2 is equipped with on-board cellular connection, allowing direct communication with the cloud from anywhere–regardless of whether network access is available. There is also ethernet and WiFi connectivity available.
The IO3 is the lightest weight of all the Knaq hardware. It is an accelerometer-based sensing solution which rides on the elevator car-top and collects a variety of mechanical metrics. Although more limited in its data collecting capabilities when compared to the main machine room-based Knaq devices, this small sensor gains in other areas with installation times in minutes and the ability to sense issues which may remain imperceptible to the equipment controller.
Our newest iteration of this hardware incorporates non-invasive sensor inputs used on the standard Knaq IO1/IO2 overlay device to acquire signals from the door operator.

IOC deviceDeveloped in response to customer inquiries, we developed the IOC, a device that is built to measure ambient temperature and humidity in mission-critical environments and seamlessly present that data on the Knaq data dashboard.
The IOC comes with a similarly light installation effort to other Knaq devices and is also cloud connected via a cellular connection.
