20.4.2 MULTICMDRCV and MULTICMDSND
20.4.2.1 Identification
Function description IEC 61850
identification
IEC 60617
identification
ANSI/IEEE C37.2
device number
Multiple command and receive MULTICMDRCV - -
Multiple command and send MULTICMDSND - -
20.4.2.2 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.
20.4.2.3 Setting guidelines
Settings
The parameters for the multiple command function are set via PCM600.
The Mode setting sets the outputs to either a Steady or Pulsed mode.
20.5 SPA communication protocol
20.5.1 Application
SPA communication protocol is an alternative to IEC 60870-5-103, and they use the
same rear communication port.
When communicating with a PC connected to the utility substation LAN via WAN
and the utility office LAN (see Figure
336 ), and when using the rear optical Ethernet
port, the only hardware required for a station monitoring system is:
• Optical fibres from the IED to the utility substation LAN
• PC connected to the utility office LAN
