Conveyor Synchronized
Funciton with Shift
Functions
When the first workpiece for the WORK IN/NOT shift completes the shift
section, (1) is set to the system variable $I000. When the first workpiece
for the WORK ID shift completes the shift section, (1) is set to the system
variable $I006.
In the job, these system variables are read out, and the CVQUE
instruction is executed when both the WORK IN/NOT shift and the WORK
ID shift completes the respective shift sections.
Executing the CVQUE instruction sets the head information of WORK IN/
NOT shift data and WORK ID shift data to the system variables $I012 and
$I018 respectively and switches the reference workpiece for
synchronization start to the next reference workpiece.
NOTE
• When the conveyor synchronized function with shift
function is valid, insert the CVQUE instruction and the
SYEND instruction between the SYEND instruction and
the next SYSTART instruction, whether the Start Shift
function is used or not.
• Be sure to program the SYEND instruction at the
beginning of the master job to reset the registered status
of the conveyor’s home position.
