Communication manual 8400 motec CANopen

Implemented CANopen objects

I-1005 - COB-ID SYNC message

This object can be used to activate the generation of sync telegrams and to write the

identifier value.
This object relates to codes

C00367

and

C00368

.

Creating sync telegrams
Sync telegrams are generated by setting bit 30 (see below) to a value of "1". The time

interval between the sync telegrams can be set using object

I-1006

.

Writing identifiers
For the reception of PDOs, the value 0x80 is entered in the Lenze setting (and according to

CANopen specification) into the 11 bit identifier. This means that all modules are set to the

same sync telegram by default.

 If sync telegrams are only to be received by certain communication modules, their

identifiers can be entered with values up to and including 0x07FF.

 The identifier may only be changed when the communication module does not send

any sync telegrams (bit 30 = "0").

 How to change the identifier:

– Deactivate identifier (set bit 30 to "0").
– Change identifier.
– Activate identifier (set bit 30 to "1").
