| # Effectivity Unit - Process Variables (tirou1114m000) Use this session to make the target value of a process variable customer-specific by linking the process variable to an effectivity unit. A process variable is one of the features of a microrouting, and is used to establish settings or adjustments for a product. Related topics Overview of unit effectivity Microrouting To set up a microrouting Effectivity Unit A reference number, for example a sales order line or a project deliverable line, that is used to model deviations for a unit effective item. Configuration Ready If this check box is selected, all desired requirements are selected for the unit effective item. Process Variable A setting or an input value related to a machine, a tool, or to process quality that is relevant to carry out an operation or an operation step. For example, cutting depth, cutting speed, and temperature. Deviation Expressed In How the deviation of the target value is expressed, Absolute or as a Percentage. Default value This field has a default value taken from the Deviation Expressed In field in the Process Variables (tirou0105m000) session. Target Value The process variable's target value. Upper Control Limit The process variable's upper control limit that is expressed as an absolute value or as a percentage. Absolute If the upper control limit is expressed as an absolute value, the value is defined to which the process variable's target value can be exceeded. For example, if the target value is 30 and the upper control limit must not exceed 33, 33 is displayed this field. Percentage If the upper control limit is expressed as a percentage, the percentage is defined with which the process variable's target value can be exceeded. For example, if the target value is 30 and the upper control limit must not exceed 33, 10% is displayed in this field. Lower Control Limit The process variable's lower control limit, which is expressed as an absolute value or as a percentage. Absolute If the lower control limit is expressed as an absolute value, the minimum value is defined that the process variable's input value can be lower than the target value. For example, if the target value is 30, and the lower control limit must not be lower than 27, 27 is entered in this field. Percentage If the lower control limit is expressed as a percentage, the percentage is defined that the process variable's input value can be lower than the target value. For example, if the target value is 30, and the lower control limit must not be lower than 27, 10% is entered in this field. |
