10.10 Store and restore functionality
By means of the CANopen objects 1010
h
(store parameters) and 1011
h
(restore default parameters), the param-
eter data set by means of CANopen (  section 10.7.2 "Parameter data" on page 63) can be stored or restored
retentively.
The following commands are supported:
• 1010
h
/01
h
: Save all parameters
• 1010
h
/04
h
: Save manufacturer defined parameters
• 1011
h
/01
h
: Restore all default parameters
• 1011
h
/04
h
: Restore manufacturer defined default parameters
The following manufacturer-specific CANopen elements are saved or restored. ‘All parameters' and 'manufacturer
defined parameters' handle the same elements.

and 4015

. Thus, no communication-specific CANopen parameters are stored and restored.
For saving the elements, the value 0x65766173 (“save”) must be written into the CANopen object 1010
h
/xx.
For loading the default values, the value 0x64616F6C (“load”) must be written into the CANopen object 1011h/xx.
After a “Restore default parameters” service, the default values are not active until a node reset service has addi-
tionally been executed, or a device restart has been carried out.
The saved CANopen object values are used as default values when the device is restarted.
10.11 START command
A START request (ST bit) is only accepted if there is no alarm and the AUTOCAL function is not executed. To
avoid uncontrolled heating in case of CAN communication problems, a START request (ST bit) must be sent cycli-
cally. The cyclic setting of the START request (ST bit) can be done either by SDO or by PDO.
The maximum cycle time for a START request can be set. The corresponding timeout is defined in CANopen
object 4013
h
/00
h
(“Start retrigger timeout [ms]”). After the timeout has elapsed without the START request being
resent, the controller automatically terminates the heating phase and switches to measurement mode. The value
of “Start retrigger timeout” can be adjusted to the project’s frame conditions. For security reasons, it is not possible
to switch off the timeout.
10.12 Heating time limit
The heating time limit can be used to activate additional monitoring against unwanted continuous heating. If the
start bit should remain set longer than the time set by the heating time limit, then the RESISTRON
®
Temperature
Controller RES-5009 automatically switches off the heating impulse after the set heating time limit has expired.
The start bit must be reset before the controller is restarted.
The heating time limit is switched off as standard (value 0) and can be selected between 0 s and 99.9 s (0 and
999).
