The Communication node describes the direct communication connection possibilities between logical nodes by means of
logical buses (sub-networks) and IED access ports. The communication section is structured as follows.
Figure C–8: SCD FILE STRUCTURE, COMMUNICATIONS NODE
The SubNetwork node contains all access points which can (logically) communicate with the sub-network protocol and
without the intervening router. The ConnectedAP node describes the IED access point connected to this sub-network. The
Address node contains the address parameters of the access point. The GSE node provides the address element for stat-
ing the control block related address parameters, where IdInst is the instance identification of the logical device within the
IED on which the control block is located, and cbName is the name of the control block.
