4.2Messages IDs

Message IDs are one byte long and have the following general format:

Type (CAN, BEAN,

Command (Cmd=1)

Tx (1) / Rx (0)

Time Stamp (TS)

ACP,Class 2, IIC, etc)

 

 

 

 

 

 

 

Bits 3 - 7

bit 2

bit 1

bit 0

 

 

 

 

The upper nibble indicates the type of message. The following types are defined:

Gateway (08)

Keyword 82 (10h)

Keyword 71 (18h)

IIC (20h)

Keyword 2000 (28h)

IDB (30)

ACP (38h)

E&C (40h)

J1708 (48h)

CAN (50h)

Class2 (60h)

Class2 Block (68h)

SPI (70h)

BEAN1 (90h)

BEAN2 (98h)

Bits 3 to 7 identify the specific communication bus (i.e., Class 2, CAN bus, etc.). Bit 2 is used to designate a command or setup message when set to 1. Bit 1 is the transmit or receive bit with 1 designating transmit and 0 designating receive. Bit 0 is used to designate the Time Stamp. In general, report messages from the gateway use the same identifiers as commands to the gateway.

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.
