The node address is transferred to LNT via the local HMI by setting the parameter
ServicePinMsg = Yes. The node address is sent to LNT via the LON bus, or LNT can
scan the network for new nodes.
The communication speed of the LON bus is set to the default of 1.25 Mbit/s. This can
be changed by LNT.

Identification
Function description
Multiple command and receive
Multiple command and send
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.
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.
SPA communication protocol
Application
SPA communication protocol is an alternative to IEC 60870-5-103, and they use the
same rear communication port.
