This sectiontherefore addresses programming experts.8.9.5.1 IntroductionAcylic communications are used to read and write parameters anddiagnostics from and to the DS7-SWD soft starter and, optionally, the PKEmotor-protective circuit-breaker; they can take place at the same time ascyclic data is being transferred. This means that acyclic communications areindependent from the selected profile.In this case, the SWD coordinator (client) communicates acyclically with theDS7-SWD soft starter (server) and, optionally, with the PKE motor-protectivecircuit-breaker. Communications are always initiated by the client.￫ For information on the subject of the “transfer of cyclic data”,consult manual MN05013002Z-EN, “SmartWire-DT Gateways.”￫ In order for acyclic data to be transmitted and diagnosticactivities to be performed, the higher-level PLC must featureacyclic services.The programmable EASY802-DC-SWD and EASY806-DC-SWDswitchgear and controlgear do not feature acyclic services!
