This is why a clearidentification of the tightening results is necessary, to be able to e.g. assign archived tightening results ata later point. The CS351 Compact System enables identification of every tightening result record with anidentification code (ID code) provided by the partner controller 1) .The 3964R/RK512 protocol can be used to transfer the ID codes to the Compact System and also tosend tightening results to the partner controller.1) The ID code may contain up to 64 ASCII characters, such as e.g. a workpiece number, productionnumber, serial number, chassis number, etc.System 350 | 3 608 878 040/05.2008
