Horizontal communication
Network variables are used for communication between 500 series and 670 series
IEDs. The supported network variable type is SNVT_state (NV type 83). SNVT_state
is used to communicate the state of a set of 1 to 16 Boolean values.
Multiple command send function block (MULTICMDSND) is used to pack the
information to one value. This value is transmitted to the receiving node and presented
for the application by a multiple command function block (MULTICMDRCV). At
horizontal communication the input BOUND on the event function block
(MULTICMDSND) must be set to 1. There are 10 MULTICMDSND and 60
MULTICMDRCV function blocks available. The MULTICMDSND and
MULTICMDRCV function blocks are connected using Lon Network Tool (LNT 505).
This tool also defines the service and addressing on LON.
This is an overview for configuring the network variables for 670 series IEDs.
Configuration of LON network variables
Configure the Network variables according to the specific application using the LON
network Tool. For more information, refer to LNT 505 in Operation manual. The
following is an example of how to configure network variables concerning, for
example, interlocking between two IEDs.
