(for example, a “0” binary coil converts to “0” in a input register, and an non-zero value in a holding register converts to “1” in an input status), either between the client and the MBLogic server, or between the client and the slaves (field devices). The following python program reads 10 characters from the serial port and sends back it. Pymodbus is a full Modbus protocol implementation using twisted for its asynchronous communications core. This software supports the ‘Modbus RTU’ and ‘Modbus ASCII’ serial communication versions of the protocol, and is intended for use on Linux, OS X and Windows platforms.
