TwinCAT PLC IEC 60870-5-101, -102, -103, -104 Master

Four telecontrol libraries are available that comply with the globally accepted IEC 60870 standard.

The -101 specification standardises a protocol for serial coupling. A master can be realised via a comprehensive function block library for TwinCAT PLC.

The 102 protocol serves for the transmission of counter states of electrical energy quantities. These values are usually transmitted at longer periodic intervals. Special safety measures ensure that the values cannot be falsified. The TwinCAT PLC library implements a serial interface, via which the individual ASDUs (application-layer service data units) can be sent or received.

The serial 103 version is the communication standard for substation control. The protocol is used for serial communication with digital protective equipment protecting the electric energy transmission network from the effects of faults (short circuit, earth leakage) in individual power supply units. For the purpose of monitoring these protective devices, all states are transferred to the control master station via a serial IEC 60870-5-103 protocol.

Like the -101 version, the -104 protocol defines a general communication standard. In contrast to the -101 standard, the communication is realised via TCP/IP.

Interoperability between devices from different manufacturers is ensured through the "interoperability list", the structure of which is defined in the standard. For the TwinCAT libraries interoperability lists are available for each product in the Beckhoff Information System.
