Data Field

The Data Field defines the data transfer requirements of the application layer message. This field describes the data using the ‘data type’ defined in Section 2.l. Commas separate individual elements of data.

As previously discussed in Section 3, there are two types of application layer packets–. Command and Response. Command packets ALWAYS contain a transaction number (USINT). Response packets ALWAYS contain a transaction number (USINT) and a status (USINT). The transaction specification is only concerned with the data field portion of these messages. The transaction number and status are assumed to be present, and are not shown in the specification.

In transactions that fit the basic Set, Get, and Set/Get definitions, only a single data field is described in the specification. In these cases it is assumed that a ‘Set’ transaction has only Command packet data. A ‘Get’ has only Response packet data. And a ‘Set/Get’ has the same data in the Command and Response packet, unless it is being used to ‘Get’ only, in which case there is no Command data.

Transactions are not required to conform to these basic rules. When such exceptions exist, both their Command and Response data fields will be described in detail. The command data field is preceded by a C:, the response data field is preceded by a R: for identification purposes only.

In some cases variable names are given in the data field specification. These names are used to describe multiple elements of a common data type. These names are not required for use, but may be included in present and future software drivers and libraries provided by Baldor. (When used with tools provided by Baldor, variable names are case sensitive.)
