IEC 60870‑5‑101, ‑103, ‑104 are standardized, vendor-independent protocols. With SIPLUS RIC, they can be parameterized with the SIMATIC Manager or TIA Portal without the need for additional installations.
The IEC 60870-5-101 protocol supports classical WAN connections via dedicated lines,
The coupling is made
- directly
- via media converters (e.g. modems) or
- via the serial interfaces (RS232 or RS485) of the communications modules, e.g. 1SI, CP 341, CP 441 or CM PtP/PTP
The IEC 60870-5-103 protocol permits serial communication with protection devices, e.g. SIPROTEC. The link is made similar to IEC 60870-5-101 via serial communications modules.
The IEC 60870-5-104 protocol supports TCP/IP-based WAN connections such as internet/DSL or GPRS/UMTS/LTE. Either the PN interfaces of the CPUs or the Industrial Ethernet communications modules, e.g. CP 343, CP 443 and CM/CP 154x, are used as interfaces. Redundancy groups and substitute routes (combinations of serial and Ethernet transmission paths) are both possible and enabled via the interfaces.
Security requirements for IEC 104 communication can be achieved with:
- external components (firewall/VPN gateways such as SCALANCE S)
- integrated security features (e.g. firewall/VPN of Advanced CPs)
TLS can be used within the mechanisms (and limitations) provided by SIMATIC for the encryption of IEC 60870-5-104 communication.
The libraries for the IEC 60870-5-101 and -104 protocols are supplied as master (SCADA/Control Center/Controlling Station (control system)) and slave (substation/RTU/Controlled Station) including activation for PN-CPU and CP interface. The IEC 60870-5-103 library is only available as master.
SIMATIC Controllers can also communicate with third-party products by means of the IEC protocols and exchange data from the SIMATIC Controller.
By combining the different library variants (within a CPU), information from lower-level stations and also protection devices can be forwarded to the control stations (node or gateway functionality). Reversed direction signal paths are also supported.
The modular concept in connection with presets enables a fast configuration of stations with basic functionality. Specific requirements (e.g. individual addresses, transfer of external time stamps) can also be parameterized and programmed individually. Example projects are available to make starting easier. They can be used as a basis for one's own projects or initial tests.
Libraries including the example projects and documentation can be downloaded from Siemens Online Support as trial versions and used without a valid license (activation code) in demo mode (15 minutes of full functionality after each CPU restart).
