Galil Motion Control DMC-40 0 Series User Manual

Example- Output Bit
The Output Bit (OB) instruction is useful for setting or clearing outputs depending on the value of a variable, array,
input or expression. Any non-zero value results in a set bit.
Instruction Interpretation
OB1, POS
Set Output 1 if the variable POS is non-zero. Clear Output 1 if POS equals 0.
OB 2, @IN [1]
Set Output 2 if Input 1 is high. If Input 1 is low, clear Output 2.
OB 3, @IN [1]&@IN [2]
Set Output 3 only if Input 1 and Input 2 are high.
OB 4, COUNT [1]
Set Output 4 if element 1 in the array COUNT is non-zero.
The output port can be set by specifying an 16-bit word using the instruction OP (Output Port). This instruction
allows a single command to define the state of the entire 16-bit output port, where bit 0 is output 1, bit1 is output2
and so on. A 1 designates that the output is on.
Example- Output Port
Instruction Interpretation
OP6
Sets outputs 2 and 3 of output port to high. All other bits are 0. (2

Digital Inputs
The general digital inputs for are accessed by using the @IN[n] function or the TI command. The @IN[n] function
returns the logic level of the specified input, n, where n is a number 1 through 48.
Example - Using Inputs to control program flow
Instruction Interpretation
JP #A,@IN[1]=0
Jump to A if input 1 is low
JP #B,@IN[2]=1
Jump to B if input 2 is high
AI 7
Wait until input 7 is high
AI -6
Wait until input 6 is low
Example - Start Motion on Switch
Motor A must turn at 4000 counts/sec when the user flips a panel switch to on. When panel switch is turned to off
position, motor A must stop turning.
Solution: Connect panel switch to input 1 of DMC-40x0. High on input 1 means switch is in on position.
