MODBUS Extension Module Versions
« on: August 22, 2009, 01:18:37 PM »
Hi All

Here is a list of the MODBUS pack versions and the corresponding changes made, including some additional notes.

All registers users will receive updates sent directly via email to ensure that any relevant changes/corrections can be immediately used if required.

  • 28.07.2009 Completed AVR32 configuration and reset RTU state to idle after inter-character space error {V1.01}
    This ensures that the UART receiver in RTU mode can correctly synchronise to following frames after an inter-character space violation has been detected.
  • 06.08.2009 MODBUS USB slave support added, plus additional dependency for event counter use {V1.02}
    The MODBUS module can now be used as slave via USB CDC. This requires the processor to have a USB device interface and a corresponding CDC device be configured. A USB project example is available if required.
  • 12.08.2009 Add RTU/ASCII decision for reverse routing to UARTs        {V1.03}
    This ensures that a serial slave in ASCII mode, performing a gateway operation to a serial RTU master, returns responses in the correct ASCII mode (or inverted case RTU/ASCII)
  • 22.08.2009 Dimensions of tcp_master_timeout and tcp_master_broadcast_timeout corrected to MODBUS_TCP_MASTERS - see modbus.h {V1.04}
  • 26.08.2009 Reverse routine error corrected (introduced in V1.03): Increased flexibility in gateway routine added, explained in the updated MODBUS document. USB ASCII slave capability description also added to the document {V1.05}
Present released version V1.05
