The GOOSE messag...Yes, this is a common confusion. The GOOSE message simply has the value of the particular function as a "0" or a "1" in the actual message - none of the prefix identifier or even the LN name. The message doesn't need to contain all that extra stuff but it does contain the GOOSE identifier number. All the subscribing IED needs is to be configured to subscribe to a particular GOOSE Id and extract the particular bit out of the dataset.<br /><br />It is the engineering tools that need to be able to understand the prefix information and hence the structure of the SCD file and the extracted CID file so that each engineering tool, i.e. each ENGINEER knows what is being configured.Rod Hugheshttps://www.blogger.com/profile/14916869433788165969noreply@blogger.com
