October 24, 2010 - Colway Solutions announces a lightweight Modbus Slave Protocol stack in ‚ÄòC‚Äô source code for Modbus-TCP. Colway chose the 8 key functions from the Modbus protocol specification and have made it available as a library with either single function codes or all eight bundled together. The library takes up approximately 5KB of code space and about 512 bytes of RAM. Buying and deploying this source code offers a huge savings in development costs as compared to reading and understanding the Modbus specifications, then programming and testing the code. Typical time saved here could be 6 to 8 weeks. Packaging Modbus functions in this manner helps customers save money and device memory.LicensingCustomers may need to impart Modbus functionality to either a single product or multiple products in their portfolio. Colway Solutions royalty free licensing model supports unlimited embedded copies for either scenario. This also benefits systems integrators who may wish to deploy Modbus on specific devices for network consolidation. A single Modbus function can be deployed on a single product for $50.00.Ease Of DeploymentIn addition to packaging and licensing, Colway Solutions offers other ease of deployment features:1. Free downloadable Modbus Protocol Tester. After the source code is integrated with the application and embedded in the target device, the Colway Tester is a handy tool to check compliance, robustness of communication interface and to gather and analyze data on communications performance.2. Free ‚ÄúSemi-ports.‚Äù Colway Solutions tested and characterized their source code on popular micro-controller hardware including ARM, 8051 and Coldfire. The microcontroller specific porting steps like setting of variables and macros is already done and available free to Colway customers. Colway will add semi-ports for more micro-controller hardware over time.3. Specific task oriented on-line documentation. Engineers do not need to plow through reams of documentation ‚Äì their on-line documentation is readily available in an easy to understand ‚Äúhow-to‚Äù format for each step in the porting process.These innovations from Colway Solutions will make it easier to adopt the Modbus standard, extending the reach and popularity of the protocol.
