4.4 Primitive Logical Groups

All Siemens TIWAY Primitives fall into logical groups according to their

function, as shown in Table 4-1. Each Primitive has a request and a

response format. The device initiating the transaction formats a request

Primitive, and the device answering the request formats a response

Primitive. The TIWAY I Primitive subset is taken from the categories listed

in Table 4-1.
