17.4.2.2 Application
M14790-3 v5
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.
17.4.2.3 Setting guidelines
SEMOD119915-1 v1
Settings
M14789-4 v3
The parameters for the multiple command function are set via PCM600.
The
Mode
setting sets the outputs to either a
Steady
or
Pulsed
mode.
17.5 SPA communication protocol
IP14614-1 v1
17.5.1 Application
IP14785-1 v1
SEMOD115767-5 v7
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
221), and when using the rear optical Ethernet port, 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
