Volitans Software has joined a partnership with R Engineering, Inc to create modbusApps. Here is our first press release:
modbusApps is proud to announce modbusProbe, an application for the Apple OS X operating system to poll modbus(R) enabled control system devices. The application can poll either serially via a USB adapter or directly via TCP. There are a number of excellent Windows based programs that provide connectivity to logic solvers, but to date little development has been done with the Apple OS X operating system.
The application includes the ability to poll all four types of registers and display the results in decimal, hexadecimal, binary, or integer format. A help file has been developed to provide a basic understanding of the modbus(R) protocol. Future enhancements include the ability to monitor the data stream to and from the polled device(s) as well as providing the user to write to the device.
In addition to this application, the Cocoa Framework will be offered under the GNU License as a freedownload to give other Mac programmers the basic tools to develop modbus(R) tools for the Apple OS X operating system. The framework modbusKit may also be downloaded from the modbusApps website.
