Hydraulic valve controller

J1939 or CANopen permit networking

The AX020510 valve controller from Axiomatic (Canada) offers multi-functional hydraulic valve control via 6 inputs and 5 outputs. The Simulink software development allows programming the device for specific applications.

THE DEVICE PROVIDES CONTROL OF FIVE PROPORTIONAL or on/off solenoids over a J1939 network. PWM signal inputs, analog voltage or current inputs are accepted for interfacing to a PLC, an Engine Control Module or command potentiometers. Multiple switched inputs are provided to suit a range of applications. Each can be configured to measure the input value, and send the data to a J1939 network. CANopen is also included in the AX020511 version of the product.

In addition, any output on the controller could be configured to use any of the on-board inputs as either a control signal or an enable signal, instead of taking the control information from the CAN network. Diagnostic messages are provided over the CAN network for the status of inputs or outputs. Settings are user configurable via a Windows-based electronic assistant configuration tool interfacing to the controller via an USB-CAN device to suit a variety of applications.

A rugged power supply interface accepts 12 VDC or 24 VDC nominal for battery powered machine applications. The unit is suitable for use in outdoor and high vibration environments. The controller operates from -40 °C to +85 °C. The valve controller suits machine control applications such as excavator hydraulic attachment control, and data acquisition for monitoring the level in natural gas tanks as well as in oil and gas equipment automation and off-highway machine automation.

Simulink controls support CANopen

Simulink is a data flow graphical programming language tool for modeling, simulating, and analyzing multi-domain dynamic systems. It was developed by Mathworks (US). Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. It offers tight integration with the rest of the Matlab environment and can either drive Matlab or be scripted from it. Axiomatic generates embedded code for their ST32 microprocessor-based controllers using Simulink. Their controls programmed with Simulink support both J1939 and CANopen.

Customizable block libraries are available for control products. Customers using the Simulink modeling environment during the development of their control system can incorporate the Axiomatic controller by using the Axiomatic Hardware Interface Library (HWIL). To use the HWIL, licenses for Simulink and Stateflow are required. Code generation requires the Simulink Coder license or another compatible product.
