Output of Data Numeric and String | Galil DMC-1700, DMC-1800

In this example, the message “Enter Length” is displayed on the computer screen. The controller waits for the operator to enter a value. The operator enters the numeric value which is assigned to the variable, LENX.

Cut-to-Length Example

In this example, a length of material is to be advanced a specified distance. When the motion is complete, a cutting head is activated to cut the material. The length is variable, and the operator is prompted to input it in inches. Motion starts with a start button which is connected to input 1.

The load is coupled with a 2 pitch lead screw. A 2000 count/rev encoder is on the motor, resulting in a resolution of 4000 counts/inch. The program below uses the variable LEN, to length. The IN command is used to prompt the operator to enter the length, and the entered value is assigned to the variable LEN.

#BEGIN	LABEL
AC 800000	Acceleration
DC 800000	Deceleration
SP 5000	Speed
LEN=3.4	Initial length in inches
#CUT	Cut routine
AI1	Wait for start signal
IN “enter Length(IN)”, LEN	Prompt operator for length in inches
PR LEN *4000	Specify position in counts
BGX	Begin motion to move material
AMX	Wait for motion done
SB1	Set output to cut
WT100;CB1	Wait 100 msec, then turn off cutter
JP #CUT	Repeat process
EN	End program

Inputting String Variables

String variables with up to six characters may input using the specifier, {Sn} where n represents the number of string characters to be input. If n is not specified, six characters will be accepted. For example, IN “Enter X,Y or Z”, V{S} specifies a string variable to be input.

Output of Data (Numeric and String)

Numerical and string data can be ouput from the controller using several methods. The message command, MG, can output string and numerical data. Also, the controller can be commanded to return the values of variables and arrays, as well as other information using the interrogation commands (the interrogation commands are described in chapter 5).

Sending Messages

Messages may be sent to the bus using the message command, MG. This command sends specified text and numerical or string data from variables or arrays to the screen.
