Digital Inputs

The DMC-18x2 has eight digital inputs for controlling motion by local switches. The @IN[n] function
returns the logic level of the specified input 1 through 8.
For example, a Jump on Condition instruction can be used to execute a sequence if a high condition is
noted on an input 3. To halt program execution, the After Input (AI) instruction waits until the
specified input has occurred.
Example:
JP #A,@IN[1]=0
JP #B,@IN[2]=1
AI 7
AI -6
Example - Start Motion on Switch
Motor X must turn at 4000 counts/sec when the user flips a panel switch to on. When panel switch is
turned to off position, motor X must stop turning.
Solution: Connect panel switch to input 1 of DMC-18x2. High on input 1 means switch is in on
position.
