b)
INC (Relative Coordinate)
1)
Object moves from the start address according to the target amount of movement (as long
as the target address is configured in operation data).
2)
This INC command is using relative coordinate which means the target address number is
counted from the start address (present position before operating this command).
3)
Direction of movement is determined by the sign (+, -) and pulse output method of the
movement amount.
Pulse Output Method: High Active Mode
When the movement direction is plus (+): Forward Positioning
When the movement direction is minus (-): Backward Positioning
Pulse Output Method: Low Active Mode
When the movement direction is plus (+): Backward Positioning
When the movement direction is minus (-): Forward Positioning
*For instance,
If the start address is ‘1000’ and the target address is ‘5000,’ the PLC-S moves forward and stops at
‘6000’ (as opposed to ABS which stops at ‘5000’). The overall movement amount is ‘6000-1000=5,000.’
