An uniform description solution for devices based on DCON ASCII protocol

In the developing process of efficient SCADA systems, there can be problems generated due to the field buses diversity, and the devices connected to this field buses. Furthermore, there can be problems encountered at the integration of new devices in the SCADA systems. An effective solution is to use a method that describes these devices so that there is not required to recompile the software module of the SCADA systems. In this paper, it is presented a solution to describe the capabilities of devices based on DCON ASCII protocol. The solution is based on the Electronic Data Sheet (EDS) files that were extended in order to describe the commands, and the answers used to retrieve information for each device. This solution was integrated into a SCADA system that has a modular architecture.
