README lib60870-C {#mainpage}

lib60870 library for IEC 60870-5 based protocols in C

The current implementation contains code for the IEC 60870-5-101 (application layer and serial link layer) and IEC 60870-5-104 (protocool over TCP/IP) specifications.

Features:

  • support for all application layer message types
  • master and slave
  • balanced and unbalanced link layers (for CS 101 serial communication)
  • client/server for CS 104 TCP/IP communication
  • CS 104 redundancy group support
  • portable C99 code

Please also consider the User Guide and the API reference documentation (https://support.mz-automation.de/doc/lib60870/latest/)

Compiling and running the examples:

In the lib60870-C folder build the library with

make

Go to the examples folder and build the examples with

make

in each examples' directory.

The library and examples can also be build with CMake.

To build the library in a separate folder create a new folder as subdirectory of the project folder and run cmake to create the build files:

mkdir build cd build cmake ..

Building without common code and HAL

The library contains some common code and a platform abstraction layer (HAL) that is shared with other protocol libraries of MZ Automation (e.g. libiec61850). In order to simplify using these protocol libraries together it is possible to compile the library without the common parts.

This can be done by using the WITHOUT_HAL and WITHOUT_COMMON defines when calling make:

make WITHOUT_HAL=1 WITHOUT_COMMON=1

Building with TLS support

The library can be build with support for TLS. In order to do so you have to download mbedtls version 2.6.0.

Unpack the mbedtls tarball in the dependencies folder so that a folder

dependencies/mbedtls-2.6.0

exists.

The cmake build system will automatically detect the mbedtls source and build the library with TLS support and mbedtls included

When using make you have to call make with WITH_MBEDTLS=1

make WITH_MBEDTLS=1

Library configuration

There are different runtime and compile-time configuration options.

Compile time configuration options can be used to shrink down the library for small embedded systems. Compile time configuration can be changed by modifying the file config/lib60870_config.h.

Memory allocation

The library uses dynamic memory allocation (malloc/calloc wrapped by own functions that can be replaced when required).

The CS104 slave uses dynamic memory allocation only at setup time (when calling the function CS104_Slave_create and CS104_Slave_start/CS104_Slave_startThreadless.

For details please have a look at the User Guide.
