Modbus Poll

Modbus Poll is a Windows application that allows you to connect various types of devices using the protocol of the same name to your PC. It is possible to initiate the full testing process and manually configure the parameters of the current connection (suitable for advanced users). The tool is actively used by engineers and programmers to interact with microcontrollers. It is possible to record technical data in a plain text file for further analysis by specialists.

Connection

It is necessary to connect the external module to the computer beforehand. The main parameters for this purpose are located in the Connection section, where you can configure all the necessary parameters to create an optimal connection. You can select the protocol type and port. It is possible to transmit data via UDP and TCP protocols. The master/slave scheme is used to organize the interaction of controllers on the external interface. It allows to organize the work of devices without failures and with a minimum number of actions on the part of the user, the main stages of connection of devices are automatic. In the process of work transactions are used, which consist of service requests and responses. There is a possibility to manually initiate sending of broadcast or individual messages, this feature is also often in demand.

Monitoring

At the testing stage it is possible to monitor all stages of receiving and sending data. A separate option is responsible for activating the recording of all events in a special log. The saved logs can be uploaded to a text file, which can later be opened with any editor for convenient viewing. You can use it in the process of searching for the causes of errors, which reduces the time of their elimination. You can use all the advantages of OLE Automation technology. The possibility to use additional modules in the VBA macro language has been realized. This allows experienced users to significantly expand the functionality of the program, because you can use ready-made developments of other specialists.
