The SetStateEffecterStates command is used to set the state of one or more effecters within a PLDM State Effecter. The field comp_effecter_count indicates the number of individual sets of state effecter information that are accessed by this command. The Event Receiver acknowledges receiving the PLDM Event Message in the response to this command.
