Horizontal communication
Network variables are used for communication between 500 and 650 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 receive function block
(MULTICMDRCV). With horizontal communication, the input BOUND on
MULTICMDSND must be set to 1. There are 10 MULTICMDSND and 60
MULTICMDRCV function blocks available. These function blocks are connected
using the LON network tool (LNT). The tool also defines the service and
addressing on LON.
This is an overview for configuring the network variables for the IEDs.
Configuration of LON network variables
Configure the Network variables according to the specific application using the
LON network tool (LNT). The following is an example of how to configure
network variables concerning, for example, interlocking between two IEDs.
