WIKA Additional Instructions Pressure Transmitter with CANopen Interface D-20-9 / D-21-9 12

1010h Store Parameters

Object description

This object supports the saving of parameters in non volatile memory. By read access the device provides

information about its saving capabilities.

Entry description

Sub-Index 00h

Name number of entries

Access ro

PDO Mapping No

Data Type UNSIGNED 8

Default Value 01h

Sub-Index 01h

Name save all parameters

Access rw

PDO Mapping No

Data Type UNSIGNED 32

Default Value 01h

In order to avoid storage of parameters by mistake, storage is only executed when the signature "save" is

written to Subindex 1.

"s"

"save"

On reception of the correct signature in sub-index 1 the device stores the parameter and then confirms the

SDO transmission (initiate download response). If the storing failed, the device responds with an Abort SDO

Transfer (abort code: 0606 0000h). If a wrong signature is written, the device refuses to store and responds

with Abort SDO Transfer (abort code: 0800 002xh).

On read access to Sub-Index 1 the device provides information about its storage functionality with the

following format:
