4.5.1 DisplayValue() STX command

Function DisplayValue(Dev:Int,
Pos:Int,
Value:Double);
Parameter Value
Dev 8 ... 11
Pos Not relevant
Value Value to be output
Tab. 58: DisplayValue() parameter
Command-line syntax for outputting a numerical value to a printer module:
DisplayValue(8, 0, -12,345);
DisplayText(8, 0, '$t');
DisplayValue(8, 0, Axis2.Position);
DisplayText(8, 0, '$n');
The first STX command outputs the value -12,345. The second STX command
inserts a tab ($t). The third STX command outputs the content of variable
Axis2.Position. The fourth STX command triggers a carriage return and line feed
($n).
The application program task stops at the DisplayText() or
DisplayValue() command waiting for all characters to be output.
