3.7 General screen form variables
Register
Registers are needed to be able to exchange data between different screen forms.
Registers are assigned to a screen form. They are loaded when the first screen
form is generated and assigned the value 0 or a blank string.
REG [x]
where:
x Number of register with x = 0...19
Real or String type = Variant
Registers with x ≥ 20 are used by Siemens.
Note
Registers may not be used directly in OUTPUT blocks for generating NC code.
Register value
The assignment of values to registers is configured in a method.
Identifier.val = Register value
Or
Identifier = Register value
where:
Identifier Name of register
Register value Value of register
UNLOAD
REG[0] = VAR1 ;Assign value of variable 1 to
register 0
END_UNLOAD
UNLOAD
REG[9].VAL = 84 ;Assign value 84 to register 9
END_UNLOAD
These registers can then be assigned to local variables again in the next screen
form.
