Sourcing Output Equivalent Circuit
Code Sample
For the code sample, the load will be a relay. The output will be configured to be a General Purpose user out-
put that will be set active when a range of motion completes.
******Setup Variables******
S1=16,1,1 'set IO point 1 to be a user output, active when HIGH,
'sourcing.
******Program******
PG 100 'Enter program at address 100
MR 2000000 'Move some distance in the positive direction
H 'Hold execution until motion completes
MR -1000000 'Move some distance in the negative direction
H 'Hold execution until motion completes
O1=1 'Set output 1 HIGH
Enter EX 100 to execute the program, the motion will occur and the output will set high.
S1=16,1,1
Output, Active HIGH, Sourcing
S1=16,0,1
Output, Active LOW, Sourcing
