Read Access to a Parameter

As a basic principle, read access to a parameter is carried out as follows:

IDN of the parameter, data block element number, r (Carriage

Return)

The drive then displays the content of the data block element that was

addressed.

In order to access the operating data of the P-0-4040 parameter, for

example, the following input is required:

Step 1

Send request e.g.:

"P-0-4040,7,r" (CR)

Step 2

Drive received character.

Drive repeats request (echo)

Character sequence ":>" found in

receiver buffer?

Compare ok? Transmission error

Step 4

Delete request in receiver buffer.

All characters up to 1st "CR"

(inclusive).

Data or error number

now contained in the

receiver buffer

Step 3

To check transmission compare

request with receiver buffer (string

compare).

yes

Next character "#" in

receiver buffer

Evaluate parameter data. Read

access completed.

contents of receiver buffer:

"P-0-4040,7,r"(CR)"#xxxx"(CR)"E01:>"
