About ModBusKit
ModBusKit is an Objective-C and Cocoa framework for communicating with ModBus devices. ModBus is a communication protocol for connecting remote devices, and is most often used in industry. The protocol can connect over serial (RS-232/422/485) or TCP.
Using ModBusKit
ModBusKit can be linked like any other framework in an XCode project. The basic steps to use and connect to a ModBus device are initWithSerial or initWithTCP, openConnection, and then one of the read or write functions. End the connection with closeConnection. All programs should check compatabilityVersion before continuing, to ensure the framework has the proper interface expected.
Further documentation will be available as development continues. As this is only an alpha release, there will be bugs and incomplete implementations. Use at your own risk.
