Font and color options Broadcast function (Slave ID=0) Easy control of RS-485 converters with RTS toggle. See VBExample.vbp read/write up to 125 registers read/write up to 2000 inputs/coil Test Center menu (organize your own test string) print and print preview monitor serial data traffic serial data traffic Data logging to a text file Data logging direct to Excel context-sensitive HLP files 10 Display formats such as float, double etc. The following protocols are supported: Modbus RTU Modbus ASCII Modbus TCP/IP Modbus RTU Over TCP/IP Modbus ASCII Over TCP/IP Modbus UDP/IP Modbus RTU Over UDP/IP Modbus ASCII Over UDP/IPMODBUS POLL Function: OLE automation can be simply interfaced with Visual Basic, similar to use ActiveX controls. You can use the OLE interface to parse and display Modbus data, and then send it to the device you specify, that is, edit the data in EXCEL, and then send it to your slave device! For examples, please refer to the Excel example.xls after installation.
For VB, EXCEL provides OLE automation interface. If you are a slave device developer, you can organize and send your own test strings through the "test center" menu, and check the results returned from the device in hexadecimal format. Provide multiple formats of data, such as floating-point, double-precision, long integer (byte sequence can be exchanged). Or you can change multiple register/coil values. If you want to change a single register, simply double-click the value.
You can read and write registers and coils from any window. Each window simply sets the slave device ID, function, address, size and polling interval. It supports multiple document interfaces, that is, multiple slave devices/data fields can be monitored simultaneously. Support Modbus RTU/ASCII and Modbus TCP/IP2, function Modbus Poll is a host emulator, used to help developers test Modbus slave devices, or other MOdbus protocol testing and simulation. MBAXP: An easy-to-use ActiveX control that supports Excel, Visual Basic, Visual C++, Delphi, etc. NET control of Modbus master device, support C#, VB, managed C++ language, support Modbus RTU/ASCII. NET control of Modbus master device, support C#, VB, managed C++ language, support Modbus TCP/IP. Each interface provides OLE automation support for EXCEL reports.
Modbus Slave: Modbus slave device simulator, which can simulate 32 slave devices/address fields.
The software supports Modbus RTU, ASCII, TCP/IP. Modbus Poll: Modbus master simulator, used to test and debug Modbus slave devices.
Modbus test tools: Modbus Poll, Modbus Slave1, brief introduction website address: website provides several software tools, which can be run in windows 2000/XP/Vista/7 environment for testing And emulate Modebus devices.
