4.4.5Target address byte

This is the target address for the message and is always used together with the source address byte. Refer to the “Keyword Protocol 2000 Data Link Layer Recommended Practice” section 4.1.2 for more information.

4.4.6Source address byte

This is the address of the transmitting device which is a physical address. Refer to the “Keyword Protocol 2000 Data Link Layer Recommended Practice” section 4.1.3 for more information.

4.4.7Length byte

This byte is provided if the length in the header byte (bits 0-5) is set to 0. It allows the user to transmit messages with data fields longer than 63 bytes. With shorter messages it may be omitted. This byte defines the length of a message from the beginning of the data field (SID included) to the checksum byte (not included). Refer to the “Keyword Protocol 2000 Data Link Layer Recommended Practice” section 4.1.4 for more information.

4.4.8Data bytes

The data field may contain up to 255 bytes. The first byte of the data field is the Service Identification Byte. Refer to the “Keyword Protocol 2000 Data Link Layer Recommended Practice” section 4.2 for more information.

4.4.9Checksum byte

The checksum byte inserted at the end of the message block is defined as the simple 8-bit sum series of all bytes in the message, excluding the checksum. Refer to the “Keyword Protocol 2000 Data Link Layer Recommended Practice” section 4.3 for more information.

Gateway Systems Analysis INterface Tool (SAINT), RS-232 specifications

Delphi Gateway Systems Analysis Interface Tool (SAINT) is a robust system that brings efficiency and precision to the analysis, monitoring, and management of data between disparate systems. Designed mainly for industrial settings where reliable communication is crucial, SAINT leverages the RS-232 communication standard, a long-established protocol that facilitates serial communication between devices.

One of the main features of SAINT is its ability to connect multiple devices through RS-232 interfaces, establishing a seamless data flow. This is particularly beneficial in environments where legacy systems still play a significant role. The tool utilizes the well-known characteristics of RS-232, such as point-to-point communication, which allows for straightforward setup and configuration. This makes it easy to connect various sensors, computers, and controllers that utilize RS-232 for data exchange.

Another critical feature of SAINT is its user-friendly interface, which enables operators to visualize data and manage connected devices effortlessly. Real-time monitoring and diagnostics are integral to the system, allowing users to detect anomalies or failures promptly. The tool also supports data logging, capturing historical data that can be analyzed for trends or performance evaluations, thereby enhancing decision-making processes.

In terms of technologies, SAINT is built on modern programming languages and frameworks, ensuring high levels of efficiency and scalability. The integration with existing systems is made easier through programmable logic, which allows for custom configurations tailored to specific operational requirements. This flexibility makes SAINT suitable for various applications, including manufacturing, transportation, and utility services.

The compatibility with multiple baud rates is another significant characteristic, providing users with the ability to adjust communication speed according to their needs. This compatibility, combined with built-in error-checking routines, enhances data integrity and system reliability.

Overall, Delphi Gateway Systems Analysis Interface Tool (SAINT) provides a comprehensive solution for seamless data integration across diverse platforms, making it an essential component in modern industrial communication setups. With its emphasis on RS-232 technology, user accessibility, and flexible integration options, SAINT is positioned as a leading tool for systems analysis and monitoring in a variety of operational environments.
