Horizontal communication

Network variables are used for communication between 500 and 670 series

IEDs.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.
