MODBUS extension package - welcome
« on: July 22, 2009, 01:47:39 PM »
Hi All

The uTasker MODBUS extension package has been introduced to the project with the uTasker version V1.4.

Its features can be summarised as follows:

•   Multiple serial master and slave interfaces (limited only by processor UART availability)
•   Multiple slaves at each UART interface (each with its own slave address, resources and application interface)
•   Routing of received messages to other MODBUS master interfaces based on function codes, access ranges or other decisions.
•   RS485 RTS control
•   Serial/serial bridge function

•   Multiple master and slave TCP ports
•   Each slave TCP port supports multiple sessions (multiple master connections)
•   Configurable idle connection timeout on each TCP port
•   Multiple slaves on each TCP port (each with its own slave address, resources and application interface)
•   Slave gateway operation to TCP or serial MODBUS masters
•   Slave routing operation to multiple TCP or serial masters via a single TCP port

•   Autonomous handling of commands and requests or with application intervention.
•   Coils and discrete elements can be optimally overlaid with registers (architecturally independent)
•   Simple generation of public MODBUS function data content, simplifying application interface.
•   Supports delayed slave responses while external data is accessed.

This package thus contains everything required for just about any MODBUS requirement in a single file, designed for flexibility, ease of use and efficiency. The software is compatible with most of the processors supported by the uTasker (see the MODBUS user's guide for details about your particular processor).

This forum board is available for general MODBUS discussions as well as specific details to the uTasker MODBUS package.
