Set Data PDU

Size: 448
Description: Initializing or changing internal state information shall be communicated using a Set Data PDU. The Set Data PDU shall consist of the following fields:

a) Simulation Management PDU Header - These field 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.
b) Request ID - This field shall identify the set data request being made by the simulation manager. This field shall be represented by a 32-bit unsigned integer.
c) Datum Information - This field shall specify the types of datum and their value to be communicated. This field shall be represented by a Datum Specification Record (see 5.3.10).

The Set Data PDU is represented in Table 50.
