18.4.2.2 Application
The IED provides two function blocks enabling several IEDs to send and receive signals via the
interbay bus. The sending function block, MULTICMDSND, takes 16 binary inputs. LON enables
these to be transmitted to the equivalent receiving function block, MULTICMDRCV, which has 16
binary outputs.
18.4.2.3 Setting guidelines
Settings
The parameters for the multiple command function are set via PCM600.
Mode setting sets the outputs to either a Steady or Pulsed mode.
The
18.5 SPA communication protocol
18.5.1 Application
SPA communication protocol as an alternative to IEC 60870-5-103. The same communication port
as for IEC 60870-5-103 is used.
When communicating with a PC connected to the utility substation LAN, via WAN and the utility
office LAN, as shown in figure 222, and using the rear Ethernet port on the optical Ethernet module
(OEM), the only hardware required for a station monitoring system is:
• Optical fibers from the IED to the utility substation LAN.
• PC connected to the utility office LAN.
Remote monitoring
ANSI05000715 V3 EN-US
Figure 222: SPA communication structure for a remote monitoring system via a substation
The SPA communication is mainly used for the Station Monitoring System. It can include different
IEDs with remote communication possibilities. Connection to a computer (PC) can be made
directly (if the PC is located in the substation) or by telephone modem through a telephone
network with ITU (former CCITT) characteristics or via a LAN/WAN connection.
