The low-level Modbus API is the preferred option when your application needs a high level of control over the sequencing and timing of Modbus requests. The low-level API is typically also the preferred choice where flexibility is paramount. In contrast, the flexibility and power offered by the LabVIEW Modbus API also means that your application code must be more complex to correctly manage the API. To help you understand this complexity, LabVIEW provides two examples.Modbus Introductory ExampleThe first example, Modbus Library.lvproj, provides a basic overview of the API’s functionality. It also demonstrates the differences between an implementation on a PC and a real-time target. Figure 3 shows the code involved in the Real-Time Modbus Master example.Figure 3: Master on RT Target.viThis example demonstrates the core requirements of a Modbus application using the LabVIEW API. First, a Modbus instance is created. In this case, a TCP master. However, you can switch this example to a serial master by changing the polymorphic instance selector.Figure 4: Changing the Type of Modbus MasterWhen the instance is created, you can begin polling the slave device for data. The example shows the use of the function code Read Input Registers. All Modbus function codes supported by the API are shown on the appropriate palette. Because of implementation of the protocol, the slave API has additional functions that the master cannot implement. For example, a slave can write to the input register range, while a master may only read from that range. Figure 5 shows the function codes.Figure 5: Modbus Master and Slave Palettes Showing the Function CodesFinally, the Modbus instance is closed, de-allocating the memory associated with the instance. This also closes any references, including the TCP connection or NI-VISA serial references used by the instance.Only the master example has been discussed thus far; however, everyMODBUS ASCII/RTU master and slave simulation

You see, i'm new with modbus, it just so happened that the device that I am going to read from (the modbus slave) is an Intellisys controller by Ingersoll-Rand it has a 2-stop bit property (can not be changed!) and the S7-200 is by default a 1 stop bit device which can not also be changed. I have tried the Modbus master program but it's not working. With the MODBUS® slave protocol Instructions, you can configure the S7-200 to act as a MODBUS® RTU slave device and communicate to MODBUS® master devices.

This is the 4th Tutorial in the Modbus Series, and today we will start the STM32 as a slave Device. This tutorial will cover how the STM32 as a slave device will send a response to the queries regarding reading holding registers and input registers.We will cover the function codes FC03 and FC04 in this tutorial, but from the slave prospective.I have already mentioned in the previous modbus tutorials that RS485 is not a requirement by the modbus, rather the mosbus protocol can be used with any communication standard.Today I am going to use the UART with the modbus protocol. I am using the STM32F446 nucleo board and it’s easier to communicate with the computer using the UART.CubeMX SetupBelow is the image of the cubeMX setupHere I am using the UART2 with the Baudrate of 115200. The configuration is 8-N-1. I have also enabled the interrupt. The pins PA2 and PA3 are configured as the TX and RX pins respectively.The Master SotwareI am using the simply modbus master software, which can be downloaded from software is shown belowHere in the RED BOX we have the serial configuration. It is same as what we configured in the cubeMX.The 115200-8-N-1 configurationThe GREEN BOX contains the slave ID, The start Register, the number of Registers master wants to Read, the function code and the Register size.The BLACK BOX contains the query to be sent by the master. It is based on the setup we did in the Green box.The BLUE box contains the response received by the master. It will update once the slave send some response.The YELLOW BOX contains the resisters master has requested the values for. These will update once the slave send the data.Some insight into the CODEDefines// in the main.c uint8_t RxData[256];uint8_t TxData[256];// in the modbusslave.cextern uint8_t RxData[256];extern uint8_t TxData[256];extern UART_HandleTypeDef huart2;// in the modbusslave.h#define SLAVE_ID 7#define ILLEGAL_FUNCTION 0x01#define ILLEGAL_DATA_ADDRESS 0x02#define ILLEGAL_DATA_VALUE 0x03static uint16_t Holding_Registers_Database[50]={ 0000, 1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999, // 0-9 40001-40010 12345, 15432, 15535, 10234, 19876, 13579, 10293, 19827, 13456, 14567, // 10-19 40011-40020 21345, 22345, 24567, 25678, 26789, 24680, 20394, 29384, 26937, 27654, // 20-29 40021-40030 31245, 31456, 34567, 35678, 36789, 37890, 30948, 34958, 35867, 36092, // 30-39 40031-40040 45678, 46789, 47890, 41235, 42356, 43567, 40596, 49586, 48765, 41029, // 40-49 40041-40050};I have defined the RxData and TxData buffers in the main file.

Example follows the same basic pattern familiar to most LabVIEW users: open, read/write, and close.Finally, although the API does look the same, it is important to understand the key difference. If your device is a master, it must send a request across the network to the appropriate slave to acquire data. The slave, on the other hand, has its own local data storage and can access it quickly.Redundant Master ExampleThe basic example may suffice for some applications; however, it may not be enough for complicated applications where the goal is to talk to a sensor or gateway. To help bridge this gap, a sample application shows how to use two masters to communicate with a given slave. If one of the masters fails and loses connection with either the slave or human machine interface (HMI), the other master takes over.Figure 6: Design of the Redundant Master ExampleIf this design meets the needs of your application, or if you are interested in a more complex example of Modbus communication, view Redundant Modbus Masters.lvproj in the Example Finder.Comments
