Chapter 2 Devices 2_ 2-19 Latched Attribute Default OFF STOP RUN SM Function ON RUN STOP *SM586 Used to calculate the interval frequency of acceleration and deceleration (for axis 1-4) OFF OFF – N R/W OFF *SM587 When TPO instruction uses position planning table to control the output, if the output is stopped during execution, the axis should refer to its relevant flags (e.g. SM476, SM496--SM576) for the action to stop. OFF OFF – N R/W OFF SM600 Zero flag OFF – – N R OFF SM601 Borrow flag OFF – – N R OFF SM602 Carry flag OFF – – N R OFF SM604 Setting the working mode of the SORT instruction. ON: descending order OFF:
ascending order OFF – – N R/W OFF SM605 Designating the working mode of the SMOV instruction. OFF – – N R/W OFF SM606 8-bit or 16-bit working mode. ON: 8-bit OFF: 16-bit OFF – – N R/W OFF SM607 Matrix comparison flag. ON: Comparing equivalent values. OFF: Comparing different values. OFF – – N R/W OFF SM608 Matrix comparison complete. When the last bits are compared, SM608 is ON. OFF – – N R OFF SM609 When SM609 is ON, the comparison starts from bit 0. OFF – – N R OFF SM610 Matrix bit search flag. When the matrix search finds the matching bits or completes the search, the search stops immediately and SM610 is ON. OFF – – N R OFF SM611 Matrix pointer error flag.
When the value of the pointer exceeds the comparison range, SM611 is ON. OFF – – N R OFF SM612 Matrix pointer increasing flag. The current value of the pointer increases by one. OFF – – N R/W OFF SM613 Matrix pointer clearing flag. The current value of the pointer is cleared to zero. OFF – – N R/W OFF SM614 Carry flag for the matrix rotation/shift/output. OFF – – N R OFF SM615 Borrow flag for the matrix shift/output. OFF – – N R/W OFF SM616 Direction flag for the matrix rotation/shift. OFF: the bits are shifted leftward. ON: The bits are shifted rightward. OFF – – N R/W OFF SM617 The bits with the value 0 or 1 are counted. OFF – – N R/W OFF SM618 ON when the matrix counting result is 0.
OFF – – N R/W OFF SM619 ON when the instruction EI is executed. OFF OFF – N R OFF SM620 When the results from the comparison using the instruction CMPT# are that all devices are ON, SM620 is ON. OFF – – N R OFF SM621 Setting counting mode for HC0. HC0 counts down when SM621 is ON. OFF – – N R/W OFF
