12.37 3003h – Unlock CAN configuration
This object is used to authorize write access on objects 3001h and 3002h used to configure the
NODE-ID and the baud rate.
The unlocking key 37h must be written to object 3003h – subindex 00h prior to making any
node ID or baud rate modifications:
CAN-ID
Command
(600h+ID)
620h
12.38 3100h – Vacuum level variation (retransmit TX PDO)
This parameter is used to define the triggering level of the TX PDOs used to measure vacuum
values.
The triggering level is defined using the following command:
CAN-ID
Command
(600h+ID)
620h
The value of the Transmission Level for PDOs (TL-PDO) must range from 0 to 100 (64h).
How it works
As soon as the vacuum value of a module varies by more or less "TL-PDO", the PDO associated
with the module in question is transmitted on the CANopen® bus.
Example (TL-PDO=5)
Time T0:
Time T0+1:
 TX PDO 2 is transmitted (it contains the vacuum values of the modules at addresses #8, #9, #10,
#11, #12, #13, #14 and #15).
If this function is not required, set TL-PDO = 100.
IMPORTANT
Object 3100h is not
restarted.
TX PDO – Vacuum value feedback
Refer to section "Messaging" which describes the mapping of the TX PDOs.
