Operation principle

The DATAVALID output will be 1 (high) as long as the incoming message contains valid data. In case
of invalid data SPOUT will be forced to 0.
The COMMVALID output will become 0 (low) when the subscribed GOOSE messages are not
received as expected. In this case SPOUT will retain the last valid value.
The TEST output will go HIGH if the sending IED is in test mode.

IEC 61850-9-2(LE) merging unit

Introduction

The IEC 61850-9-2 standard defines a process bus for transmitting sampled values of primary
voltage and current signals over Ethernet. "LE" (Light Edition) is a commonly agreed implementation
guideline, which defines a practical subset of IEC 61850-9-2 to allow straightforward implementation
and application.
IEC 61850-9-2(LE) defines a logical device Merging Unit (MU). A MU collects up to four individual
current and four voltage signals and merges them into a single data stream.
In the Switchsync PWC600 IED, sampled values streams from up to four MUs are received on the
LAN2 A port of the communication interface module COM03. The application can access them as
outputs of the MUx_4I_4U function blocks (x = 1...4) and use them in the same manner as analog
inputs on a TRM or AIM card.

The input of this GOOSE block must be linked in SMT to receive the binary single
point values.
The implementation for IEC 61850 quality data handling is restricted to a simple
level. If quality data validity is GOOD then the DATAVALID output will be HIGH. If
quality data validity is INVALID, QUESTIONABLE, OVERFLOW, FAILURE or OLD
DATA then the DATAVALID output will be LOW
