The rework instructions can be in the form of a text or number on the LCD or TFT display,or be output via appropriate control signals. For example, signal lamps can be actuated via the signaloutputs if there is a suitable PLC assignment table.31 rework codes are provided internally. These codes can each be assigned a text (max. 80 characters).The code is output as a binary encoded control signal.Rework codes are only offered on the channel level. The rework codes are also set as a 5-bit number(Ch x.y RC0 to Ch x.y RC4) along with the results of a tightening (Ch x.y OK or Ch x.y NOK).10.1.7.1 Rework code assignment and rework instructions entryThe rework codes are entered in the BS350 operating system along with the quality codes. On delivery,no rework codes are assigned in the system's assignment table (System → Quality code).System 350 | 3 608 878 040/05.2008
