    30 Machine Parameters 30.1 What is a Machine Parameter? A contouring control must have access to specific data (e.g., traverse distances, acceleration) before it can execute its programmed instructions. You define these data in what are known as machine parameters. This list of machine parameters is divided into groups according to topic.
  • Page 466 If the machine manufacturer has not commented the MP list completely or not at all, you can refer to PLC:\JH\LIES_MP.A or READ_MP.A and read the HEIDENHAIN comments on the individual parameters. LIES_MP.A or READ_MP.A is updated with each NC software update.
  • Page 467 Possibilities of The PLC program of the machine manufacturer is in a position to read machine parameters and the PLC also to overwrite most of them! During overwriting MPs by the PLC, the values are changed in the run-time memory. The values of the original MP list do not change! Another MP file (that of course must exist on the control's hard disk) can be selected by means of the PLC.
