Call example
CALL FC 22 (
//Tool management direction selection
MagNo := 2, //Magazine number

//Return parameters
Cw := m 30.0, //Move magazine
//in clockwise direction
Ccw := m 30.1, //Move magazine
//in anticlockwise direction
InPos := m 30.2, //Magazine in position
Diff := mw 32, //Differential path
