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
