CAS Modbus Scanner

A good communication is what keeps everything going round. This is also the case for machines, where a modbus is widely used to establish a fast and efficient communication method between electronic devices. What's more, applications like CAS Modbus Scanner let you analyze data from a modbus enabled device and send back custom commands.

The application works based on a series of tasks which you need to create as soon as the it is launched. These consist of a connection between your machine and the modbus enabled device, the device itself, as well as requests and commands that travel through the existing connection.

You are not limited by the number of connections you can add, with two types available, either a serial or TCP connection. The latter only requires you to provide IP, port and timeout, while the first asks for a little more attention to details, with fields for baud rate, data bits, stop bits and parity.

Tasks are the main tools used in the application. Requests can be issued to read coil or input status, as well as holding and input registers. Depending on how much data you want gathered, more requests can be made for the same connection, or simply have offset and length modified.

The write task features a similar creation process, the only difference is that the device is affected by what you send. Length is no longer a concern, with the possibility to specify offset and value, to force single or multiple coils or registers.

Once everything is set up, the connection must be established, so that you can select tasks you want to use with the device. All action is recorded with the possibility to quickly gain access to the log file which you can save to a text file.

Taking everything into consideration, we can say that CAS Modbus Scanner is not intended for everyone, with a great deal of attention required to specifying the correct task values. No help manual is there to get you out of sticky situations, but advanced users shouldn't have hard time getting acquainted with available features.
