A.4 Using Multiple sDIO Modules

Additional sDIO modules can be added to a system. The recommended maximum is four sDIO modules for a SmartController CS system and eight sDIO modules in a CX. See Figure A-5for cabling and configuration information. Note that each sDIO must have a unique block number (between 16 and 31) for both the input and output signals.

1.Connect a 24VDC cable from the XDC2 port on sDIO #1 to the XDC1 port on sDIO #2. See the “Connecting Power” on page 30 for cabling requirements.

2.Connect an IEEE 1394 cable from one of the IEEE 1394 ports on sDIO #1 to one of the IEEE 1394 ports on sDIO #2.

3.Execute CONFIG_C and select a block number for sDIO #2. Block 17 is recommended. See “Modifying the Default sDIO Configuration” on page 98 for details on this process.

4.In CONFIG_C, continue to assign groups of signal numbers to bytes 1 to 4 in the block. See “sDIO Signal Mapping Example 2” on page 101.

5.Repeat steps 1 to 4 for each additional sDIO module.

6.Exit CONFIG_C and reboot the controller.

RS-422/485, XSYS, XUSR, RS-232/TERM specifications

Nortech Systems offers a comprehensive suite of serial communication solutions, including RS-232/TERM, XUSR, XSYS, and RS-422/485 interfaces. These products are designed to facilitate reliable and high-speed data transmission in various industrial applications, making them essential for connecting devices in automation, telecommunications, and data acquisition systems.

The RS-232/TERM interface is a widely adopted standard for serial communication, known for its simplicity and robustness. It supports point-to-point communication over relatively short distances, typically up to 50 feet. Key features include a maximum baud rate of up to 115.2 kbps, error-checking capabilities, and a straightforward connection process, making it ideal for connecting peripheral devices like printers, modems, and barcode scanners.

Building on the RS-232 standard, the XUSR and XSYS devices offer enhanced functionalities and flexibility. XUSR, for instance, supports not just traditional RS-232 connections, but also protocol conversion for various serial interfaces, facilitating seamless integration of legacy systems with modern networking technologies. It is particularly useful in environments where multiple protocols need to be managed simultaneously.

XSYS is designed for more complex applications and supports advanced communication features such as multi-drop configurations, enabling it to connect multiple devices on a single bus. This makes it suitable for extensive industrial networks where space and wiring complexity need to be minimized. Synchronous and asynchronous data transfer modes ensure that the XSYS is adaptable for both real-time data collection and standard command-response applications.

On the other hand, RS-422/485 interfaces excel in long-distance communication, allowing for data transmission over distances up to 4,000 feet. They are designed for multi-point connections, supporting up to 32 devices on a single bus through differential signaling, which enhances noise immunity. These characteristics make RS-422/485 particularly well-suited for environments with electromagnetic interference, such as factories or subways.

Nortech Systems’ serial communication solutions emphasize reliability, ease of use, and versatility. With their commitment to high performance and user satisfaction, these interfaces provide critical connectivity in today’s increasingly automated and interconnected world. Whether in data centers, manufacturing setups, or remote sensor networks, Nortech's offerings stand out for their reliability, efficiency, and adaptability, ensuring effective data communication across diverse applications.
