3.5 Request data from R2600/01

This communication makes it possible to request all values, parameters, configurations, states and equipment markings.

Thereby, the data is individually addressed per parameter index. See section 4 for the complete list of all parameter indices.

3.5.1 Request an equipment specification

The parameter index lies between 30h and 3Fh. Thus the characters "from/to channel" and "receipt No." in the control and long set are omitted.

Example: Request for equipment marking having the address = 33 = 21h (see 4.4)

Request from master (control set, see 2.2):

Equipment response (long set, see 2.3):

See 2.4.2.2 for the contents of the function field (FF).

The "data block" consists of a character 26h as marking for the R2600/01 (see 4.4).
