DOS, Linux, and QNX tools

Galil offers unsupported code examples that demonstrate communications to the controller using the following operating systems.

DOS

DOS based utilities & Programming Libraries for Galil controllers, which includes a terminal, utilities to upload and download programs, and source code for BASIC and C programs. Download DMCDOS at http://www.galilmc.com/support/download.html#dos.

Linux

Galil has developed code examples for the Linux operating system. The installation includes sample drivers to establish communication with Galil PCI and ISA controllers. The current version of the software has been tested under Redhat 6.X O.S. All source codes for the drivers and other utilities developed for Linux are available to customers upon request. Linux drivers are available for ISA and PCI cards under Kernel 2.2. Drivers are also available for the PCI card only for Kernel 2.4.

For more information on downloading and installing the Linux drivers for Galil controllers, download the Linux manual at: http://www.galilmc.com/support/manuals/lnxmanual.pdf.

QNX

Galil offers sample drivers for ISA and PCI cards for the QNX 4.24 operating system. We also offer drivers and utilities for QNX 6.2 for PCI only. Download at http://www.galilmc.com/support/download.html#linux.

Controller Event Interrupts and User Interrupts

The DMC-1700/1800 provides a hardware interrupt line that will, when enabled, interrupt the PC. This allows the controller to notify the host application of particular events occurring on the controller. Interrupts free the host from having to poll for the occurrence of certain events such as motion complete or excess position error.

The DMC-1700/1800 uses only one of the PC’s interrupts; however, it is possible to interrupt on multiple conditions. For this reason, the controller provides a status byte register that contains a byte designating each condition.

The DMC-1700/1800 provides an interrupt buffer that is 16 deep. This allows for multiple interrupt conditions to be stored in sequence of occurrence without loss of data.

The DMC-1700/1800 provides two command forms of interrupt functionality, EI and UI. Specific interrupt conditions can be enabled using the EI command, or explicit user defined interrupts can be sent using the UI command.

Enabling Event Interrupts (EI command)

To enable certain conditions, use the command EIm,n. Where the first field “m” represents a 16-bit value of conditions described in the table below. For example, to enable interrupts on X and Y motion complete and position error, set EI515 (i.e. 515=20+21+29). Once the EI command is enabled for a specific condition, an interrupt will occur for every instance of that condition, except for the items marked with an asterisk (*), they must be re-enabled after every occurrence.

These controllers are designed to meet the demands of complex motion control applications, providing users with enhanced features and innovative technologies that optimize motion precision and efficiency.

One of the main features of the Galil DMC-1700 is its ability to handle up to 8 axes of motion control. This capability makes it suitable for a range of applications, from simple point-to-point movements to intricate trajectories in multi-axis systems. In contrast, the DMC-1800 extends this functionality, supporting up to 64 axes, making it ideal for large-scale automation environments.

Both models leverage Galil's powerful programming interface, which simplifies the development of motion control applications. The DMC-1700 and DMC-1800 controllers utilize a high-level programming language that supports advanced motion commands, including linear interpolation, circular interpolation, and complex motion profiles. This feature allows users to implement sophisticated motion sequences seamlessly.

In terms of connectivity, the Galil DMC series offers multiple communication options, including Ethernet, RS-232, and CAN bus, ensuring compatibility with various hardware and enabling easy integration into existing systems. The controllers also come equipped with digital and analog I/O ports, providing flexibility for sensor feedback and actuator control.

The advanced technology incorporated into both the DMC-1700 and DMC-1800 includes on-board PID control, which ensures precise motion control through closed-loop feedback. This results in improved stability and accuracy, particularly in high-speed applications. Additionally, the controllers offer extensive diagnostics and monitoring capabilities, allowing for real-time performance analysis and troubleshooting.

Another notable characteristic of these motion controllers is their compact design, which offers space-saving advantages while maintaining high processing power. Their robust construction and ability to operate in challenging environments make them suitable for a wide range of industrial applications, from CNC machining to assembly lines.

In conclusion, the Galil DMC-1700 and DMC-1800 motion controllers stand out due to their high-performance capabilities, advanced programming features, and flexibility in connectivity. With their ability to handle complex motion control tasks efficiently, these controllers are invaluable tools for engineers and manufacturers looking to enhance their automation processes. By integrating Galil's innovative motion control technology, industries can achieve greater precision, speed, and reliability in their operational workflows.
