Modbus Poll

What is Modbus Poll?

Modbus Poll is a Modbus master simulator designed primarily to help modbus or other slave device developers who wish to test and simulate the Modbus protocol. With the interface of multiple documents, you can monitor multiple Modbus slaves and/or data areas at the same time. For each window, simply specify the Modbus slave ID, function, address, size, and search rate. You can read and write records and reels from any window. If you want to change a single record, just double-click the value. Or you can change multiple records/reels. Various data formats are available, such as float, double and long with word order exchange.

Exception errors are shown in the status line.

If you are a slave developer, you can commake and submit your own test chains in the "test center" and check the slave result in hexadecimal numbers.

OLE automation for interface with Excel. To interpret and show Modbus data according to your specific requirements. For example, edit the data in Excel and then transmit the data to your slave device!
