Size: 448
Description: When an entity receives an Action Request PDU, that entity shall acknowledge the receipt of the Action Request PDU with an Action Response PDU.

The Action Response PDU shall contain the following fields:

  1. Simulation Management PDU Header - These fields shall identify the PDU header information, the originating entity, and the intended receiving entity. The Simulation Management PDU Header shall be represented by the Simulation Management PDU Header Record described in 5.3.29.
  2. Request ID - This field shall identify the matching response to a request made by the simulation manager. This field shall be represented by a 32-bit unsigned integer.
  3. Request Status - This field shall identify the status of the requested action. This field shall be represented by a 32-bit enumeration (see Section 7 in EBV-DOC).
  4. Datum Information - This field shall specify the types of datum and the value of the datum to be communicated. This field shall be represented by a Datum Specification Record (see 5.3.10). The Action Response PDU is represented in Table 48.
