bytes in proper descending order). Using the ASCII hex values for each character,

we get 0x70 (“p”), 0x75 (“u”), 0x6B (“k”), and 0x62 (“b”) for the final resultant

hex 4 byte number of 0x70756B62.

Restore Default Parameters

The Restore Default Parameters Object allows the 1356 /1356P to restore all

flash backed-up SDO objects to their Factory settings (hard-coded in software),

Back-up settings (stored in Back-up parameter block in flash), or Normal (stored

in Normal parameter block in flash). This object can also be used to restore

(reset) the hour meter value.

Writing a special text string to this object will initiate a restore to Factory,

Backup, or Normal settings for all SDO objects stored in flash. Once this object is

written to, the next KSI cycle will cause the system settings to be loaded from the

new desired location and put into the working RAM locations (Shadow RAM).

A Restore the Back-Up Settings command (“load”) will load the data

values from the Backup parameter block, place them in RAM, and overwrite

the Normal parameter block with them. Whatever changes were made to the

Normal parameter block will be lost. The Restore Default Parameters function

should be set to 0x02 (Restore Normal Settings) so that the 1356 /1356P will

restore from the Normal parameter block on the next reset or power cycle.

Restore Factory Settings

“fact”

Restore all parameter values

0x74636166

from built-in defaults. These

are hard-coded in the software.

Restore the Back-Up

“load”

Restore all parameter values

Settings

0x64616F6C

from the Backup parameter

block. “load” is used to comply

with CANopen spec DS301.

Restore Normal Settings

“norm”

Restore all parameter values

0x6D726F6E

from the Normal parameter block.

Preset the Hour Meter

“hour”

N/A

Preset the hour meter to the

0x72756F68

value loaded into the parameter

Preset Hour (0x3062).

On reception of the correct string, the 1356 /1356P will set a Restore flag

and confirm the SDO transmission. If a wrong string or unsupported command

is written, the 1356 /1356P will not set the Restore flag and responds with an

Abort SDO.

The hour meter has a special function to reset it. Writing the string “hour”

to this index will cause the 1356 /1356P to preset the hour meter to the value

saved in the Preset Hour parameter (0x3062). Note that only the hours can be

set to a programmed value; the minutes always will be reset to 0.
