PLCcom for Modbus

The PLCcom for Modbus-API equips .NET or JAVA developer to realize optimized Modbus-Accesses from self created applications.

PLCcom for Modbus is compatible with the specification of the Modbus-Organisation.
With the library, you can easily integrate a Modbus-Master or Modbus-Slave slave into your application with just a few lines of code.
The component supports the communication types TCP, UDP, RTU, RTU over TCP and ASCII.

In addition it provides multiple listeners, optional 32Bit register, auto choice of function code while writing, choosable register number codec and many more.

A large collection of example programs and simulation software will help you to create your application. To round off our supply you’ll receive extensive documentation and free support.

The libraries, depending on version, are 100% Java or .NET files. The driver can be incorporated directly by link, and API retrievals are not necessary. It is perfectly possible to use the component in 32 or 64 bit system environments as well as across platforms.

The internal routines are optimized for high-performance access.

Also included in the scope of delivery are extensive code examples that demonstrate the extremely easy integration of PLC control to your application, and can also be used in your projects.
