For example, the following example illustrates how to display the current position of the X axis:
TP A <return> Tell position A
0 Controllers Response
TP AB <return> Tell position A and B
0,0 Controllers Response
Interrogating Current Commanded Values.
Most commands can be interrogated by using a question mark (?) as the axis specifier. Type the command followed
by a ? for each axis requested.
PR ?,?,?,? Request A,B,C,D values
PR ,? Request B value only
The controller can also be interrogated with operands.
Operands
Most DMC-40x0 commands have corresponding operands that can be used for interrogation. Operands must be
used inside of valid DMC expressions. For example, to display the value of an operand, the user could use the
command:
MG ‘operand’ where ‘operand’ is a valid DMC operand
All of the command operands begin with the underscore character (_). For example, the value of the current
position on the A axis can be assigned to the variable ‘V’ with the command:
V=_TPA
The Command Reference denotes all commands which have an equivalent operand as "Used as an Operand". Also,
see description of operands in 358HChapter 7.
