Function description
Multiple command and receive
Multiple command and send
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 209, 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.
