hi tirumala
I have questions because you said "PLC" and "robot" and "laser"
1) is the plc telling the robot to turn the laser on/off ?
2) is the robot directly turning the laser on/off ?
3) is the PLC turning the laser on/off and the robot is receiving the inputs from laser ?
3) is the PLC turning the laser on/off and the robot is receiving the inputs from PLC ?
... many more combinationsIf you dont know, show us part of the motoman where it is working with the laser AND/OR the PLC

first robot pick the part from fixture. when it reach the home position the sliding door close.(here how door is getting signal to close)

NOP
*DOORREQ
JUMP *END IF IN#(953)=OFF
DOUT OT#(954) ON
JUMP *DOORREQ IF IN#(953)=ON

Hi'
With i/o numbers that high , you obviously no using wires. It could be ethernet, device net, cclink.
You should be able to see cables or even go to the PLC and found out with card is used.I think there is a sensor wired to the PLC to report door status. Let say input i00/13 (for example)
Depending on the state of this input, the PLC sends the robot the o02/24 (for example)This o02/24 output goes to IN#(953) in the robot
The robot will answer the PLC with OT#(954)
