PLC libraries are for sale to master implementation for that telecontrol protocol from the IEC 60870-5-101, -102, -103 and -104 master. The -101 and -104 user standards are general telecontrol methods that are frequently utilized in substation communication, tunnel automation, railways, energy plant automation, wind generator communication and building services. The -102 standard is restricted to the change in counter values of electrical power. Special safety precautions be sure that the values can't be falsified. The -103 protocol is perfect for communication with digital protective products, which safeguard the electrical power network from fault or error effects (e.g. short-circuit or earth leakage in individual energy supplies). The interoperation of products from various producers is guaranteed by an interoperability list, that is saved within the Beckhoff Information System. The -101, -102 and -103 methods make use of a serial interface to speak the -104 protocol uses the TCP/IP interface.
