Q600 Command (Read Variable)
You can request the contents of any macro or system variable with the ?Q600 command; for example, ?Q600 xxxx. This shows the contents of macro variable xxxx on the remote computer.
E Command (Write to Variable)
You can use an E command to write to macro variables #1-33 and #10000-#10999.
Note: Macro variables #10550-#10580 are unavailable if the mill has a probing system. See the Operator's Manual for a list of available system variables.
The correct E Command format is ?Exxxx yyyyyy.yyyyyy where xxxx is the macro variable and yyyyyy.yyyyyy is the new value.
Note: When you write to a global variable, make sure that no other programs on the machine use that variable.
Caution: Use extreme caution when you write to a system variable. Incorrect values for a system variable can cause damage to the machine.
