Azure Database Support Blog 3 MIN READIn certain service requests, our customers encounter the following error while connecting to the database, similar like this one: "Connection failed: ('08001', '[08001] [Microsoft][ODBC Driver 17 for SQL Server]Named Pipes Provider: Could not open a connection to SQL Server [65]. (65) (SQLDriverConnect); [08001] [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired (0); [08001] [Microsoft][ODBC Driver 17 for SQL Server]A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if the instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online. (65)'. I would like to give some insights about this.The crucial point to mention is that Azure SQL Database only responds to TCP, and any attempt to use Named Pipes will result in an error.1. Understanding the Error Message:The error message encountered by our customer is typically associated with attempts to connect using the Named Pipes protocol, which Azure SQL Database does not support. It signifies a network-related or instance-specific error in establishing a connection to SQL Server, often caused by incorrect protocol usage.2. Azure SQL Database's Protocol Support:Azure SQL Database is designed to work exclusively with the TCP protocol for network communication. TCP is a reliable, standard network protocol that ensures the orderly and error-checked transmission of data between the server and client.3. Why Specify TCP in Connection Strings:Specifying "TCP:" in the server name within your connection strings ensures that the client application directly attempts to use the TCP protocol. This bypasses any default attempts to use Named Pipes, leading to a more straightforward and faster connection process.4. Error Diagnosis and Efficiency:By using TCP, any connectivity issues encountered will return errors specific to the TCP protocol, making diagnosis more straightforward. This direct approach eliminates the time spent on protocol negotiation and reduces the time to connect.5. Recommendations for Azure SQL Database Connectivity:Always use TCP in your connection strings when connecting to Azure SQL Database.Ensure that your client and network configuration are optimized for TCP/IP connectivity.Regularly update your ODBC drivers and client software to the latest versions to benefit from improved performance and security features.6. Prioritizing TCP to Avoid Unnecessary Delays in Connectivity:An important aspect to consider in database connectivity is the order in which different protocols are attempted by the client or application. Depending on the configuration, the client may try to connect using Named Pipes before or after TCP in the event of a connectivity issue. This can lead to unnecessary delays in the validation process.When Named Pipes is attempted first and fails (as it is unsupported in Azure SQL Database), the client then falls back to TCP,

Modbus TCP/IP TCP/IP TCP is Transmission Control Protocol and IP is Internet Protocol. These protocols are used together and are the transport protocol for the internet. When modbus information is sent using these protocols, the data is passed to TCP where additional information is attached and given to IP. IP then places the data in a packet (or datagram) and transmits it. TCP must establish a connection before transferring data, since it is a connection-based protocol. The Master (or Client in Modbus TCP) establishes a connection with the Slave (or Server). The Server waits for an incoming connection from the Client. Once a connection is established, the Server then responds to the queries from the Client until the client closes the connection. Modbus RTU over TCP Simply put, this is a Modbus RTU message transmitted with a TCP/IP wrapper and sent over a network instead of serial lines. The Server does not have a SlaveID since it uses an IP Address instead. Modbus TCP A Modbus Messaging Implementation Guide provided by Schneider Automation outlines a modified protocol specifically for use over TCP/IP. The official Modbus specification can be found at modbus.org/specs.php . The main differences between Modbus RTU and Modbus TCP are outlined here. ADU & PDU Aside from the main differences between serial and network connections stated above, there are a few differences in the message content. Starting with the Modbus RTU message and removing the SlaveID from the beginning and the CRC from the end results in the PDU, Protocol Data Unit. Here is an example of a Modbus RTU request for the content of analog output holding registers # 40108 to 40110 from the slave device with address 17. 11 03 006B 0003 7687 11: The SlaveID Address (17 = 11 hex) 03: The Function Code (read Analog Output Holding Registers) 006B: The Data Address of the first register requested. (40108-40001 = 107 =6B hex) 0003: The total number of registers requested. (read 3 registers 40108 to 40110) 7687: The CRC (cyclic redundancy check) for error checking. Removing the SlaveID and CRC gives the PDU: 03 006B 0003 MBAP Header A new 7-byte header called the MBAP header (Modbus Application Header) is added to the start of the message. This header has the following data: Transaction Identifier: 2 bytes set by the Client to uniquely identify each request. These bytes are echoed by the Server since its responses may not be received in the same order as the requests. Protocol Identifier: 2 bytes set by the Client, always = 00 00 Length: 2 bytes identifying the number of bytes in the message to follow. Unit Identifier: 1 byte set by the Client and echoed by the Server. The TCP Client Server configuration demonstrates creating a network client and server that uses the MPLAB Harmony TCP API.
