How to Use Modbus Poll V5.0.1 Build 450.zip to Monitor and Control Devices
Modbus Poll V5.0.1 Build 450.zip is a software tool that allows you to communicate with Modbus devices using a serial or TCP/IP connection. Modbus is a standard protocol that enables data exchange between different types of devices, such as PLCs, sensors, meters, and controllers. Modbus Poll V5.0.1 Build 450.zip can act as a Modbus master, sending requests to one or more Modbus slaves and displaying the responses in various formats. You can also use Modbus Poll V5.0.1 Build 450.zip to modify the data in the devices, such as changing settings, writing values, or triggering actions.
In this article, we will show you how to use Modbus Poll V5.0.1 Build 450.zip to monitor and control devices that support Modbus RTU or Modbus TCP protocols. We will assume that you have already downloaded and installed Modbus Poll V5.0.1 Build 450.zip from this link. We will also assume that you have a device that supports Modbus RTU or Modbus TCP and that you know its communication parameters, such as baud rate, parity, slave ID, IP address, port number, and register addresses.
Step 1: Configure the Connection
The first step is to configure the connection between your computer and the device. You can use a serial port or an Ethernet port, depending on the type of device you have.
If you are using a serial port, follow these steps:
Open Modbus Poll V5.0.1 Build 450.zip and click on Connection > Serial Port Settings.
Select the COM port that is connected to your device from the drop-down list.
Enter the baud rate, parity, data bits, and stop bits that match your device's settings.
If you are using an Ethernet port, follow these steps:
Open Modbus Poll V5.0.1 Build 450.zip and click on Connection > TCP/IP Settings.
Enter the IP address and port number of your device.
Step 2: Create a New Data Window
The next step is to create a new data window that will display the data from your device. You can create multiple data windows for different devices or data areas.
To create a new data window, follow these steps:
Click on Data Window > New Data Window.
A dialog box will appear where you can enter the parameters for the data window.
Enter a name for the data window in the Data Window Name field.
Select the protocol type from the Type drop-down list. You can choose between Modbus RTU or Modbus TCP.
Enter the slave ID of your device in the ID field.
Select the function code from the Function drop-down list. You can choose between reading or writing coils, discrete inputs, input registers, or holding registers.
Enter the starting address of the data area in the Address field.
Enter the number of registers or coils to read or write in the Data Length field.
Select the display format from the Data Format drop-down list. You can choose between binary, hexadecimal, decimal, octal, ASCII, float, double, long, etc.
Select the byte order from the Data Order drop-down list. You can choose between big-endian or little-endian.
Select the word order from the Data Order drop-down list. You can choose between high-low or low-high.
