1-15 Direct Connection

The PT can be set for direct connection to an OMRON PC to allow numeral displays, character displays, numeral editing, lamps, touch switches, and bar graphs to be directly connected to specific bits and words in PC memory. Bits can also be set that will change the displayed screen. This is possible only when the NT600M-DT121/DT211 or NT20M-DT121-V1/DT131 PTs and only when a NT600M-LK201 SYSMAC WAY Host Interface Unit is used. Also, either an NT600M-SMR31 or NT20M-SMR31 System ROM must be used in the PT.

The direct connection setting in the Tool Settings greatly affects the operation of the screen functions that read or write PC memory. Although using direc- tion connection will greatly reduce programming burden for the PC, careful preparation is required to coordinate PC memory and programming with the PT settings for direct connection. The general procedure for this is as follows:

1, 2, 3... 1. Design the required PT screens.

2.Allocate PC memory to the function elements of the screens, i.e., those elements that will directly read or write PC memory. Be sure to list spe- cific PC memory addresses, including areas, and to consider numeral table and character string table capacities.

3.Turn ON direct connection operation in the Tool Settings.

NT600M, NT-series, NT20M specifications

Omron has established itself as a leader in the field of automation and control systems, with its NT series of human-machine interfaces (HMIs) being a prime example of their innovative technology. The NT20M and NT600M models stand out in this series, showcasing a blend of advanced features, robust design, and user-friendly interfaces that cater to various industrial applications.

The Omron NT20M is characterized by its compact size and versatility. Its 5.7-inch LCD display offers clear visibility, making it ideal for applications where space is a constraint. The graphical user interface allows operators to monitor and control processes easily. One of the standout features of the NT20M is its ability to support a wide array of communication protocols, facilitating integration with different types of PLCs and other devices. This flexibility ensures that the NT20M can be seamlessly incorporated into existing systems.

On the other hand, the Omron NT600M represents a more advanced option within the NT series. Featuring a larger 10.4-inch display, the NT600M enhances the user experience with its vibrant and responsive touchscreen interface. This model is designed for more complex applications, providing richer graphical capabilities, including animated graphics and customizable screens. The NT600M also supports more extensive data logging and can handle a greater quantity of data points, making it suitable for large systems that require detailed monitoring.

Both models leverage Omron’s proprietary technologies to enhance performance and reliability. The built-in alarm functions notify operators of any irregularities in the process, enabling quick response times to minimize downtime. Additionally, the NT series incorporates advanced security features, ensuring that sensitive information is protected from unauthorized access.

Interconnectivity is a critical aspect of modern industrial systems, and the NT20M and NT600M do not fall short in this regard. They are equipped with multiple communication ports, including Ethernet, RS-232, and USB, allowing for straightforward connectivity with a range of automation devices. This ensures that operators can access real-time data and analytics, leading to informed decision-making and streamlined operations.

In conclusion, the Omron NT20M and NT600M HMIs epitomize the convergence of form, function, and technology in industrial automation. With their unique features and robust capabilities, they empower operators to enhance productivity and efficiency within their operations, underscoring Omron's commitment to innovative solutions in the realm of automation.
