WebKepware's implementation of the Modbus Ethernet driver supports client and server operations simultaneously. The server mode allows the server to receive data by exception from other Modbus Ethernet devices. The Modbus Ethernet driver now offers direct integration with Modicon Concept and ProWORX programming packages. WebUsing modulo 2 mathematics you can show that all errors with an odd number of bits are detected. As I have said before, in modulo 2 mathematics the subtraction function is replaced by the exclusive or. There are four possible XOR operations. 0 XOR 0 => 0 even => even 0 XOR 1 => 1 odd => odd 1 XOR 0 => 1 odd => odd 1 XOR 1 => 0 even => even

The only dependence is the pySerial module (also pure Python). There are convenience functions to handle floats, strings and long integers (in different byte orders). 1 Answer Sorted by: 1 It depends on the function code. Different function codes have different pdu:s. Write single register (0x06) has for instance no "byte count", but Write multiple registers (0x010) has. What function codes are being used?
