ONLINE HELP SOPAS Parameters Chapter 5 LECTOR®620 5.8.4.1.1 Check min. number of valid codes If the Check min. number of valid codes parameter is activated, the number of different codes is determined and compared with a specified minimum value (Minimum). This enables you to check, for example, whether all required codes for an object are available. Minimum The Minimum parameter is used to define the minimum number of different codes that must be identified so that a reading is classed as a GOOD READ. If the specified value is not reached, the reading is classed as invalid (NO READ). All codes that differ from the other codes in terms of the symbology, code length, code contents, or code positions are counted. 5.8.4.1.2 Check max. number of valid codes If the Check max. number of valid codes parameter is activated, the number of different codes is determined and compared with a specified maximum value (Maximum). This enables you to ensure, for example, that only the required codes for an object are available. Maximum The Maximum parameter is used to define the maximum number of different codes that can be identified so that a reading is classed as a GOOD READ. If the specified value is exceeded, the reading is classed as invalid (NO READ). All codes that differ from the other codes in terms of the symbology, code length, code contents, or code positions are counted. 5.8.4.2 Evaluation conditions Conditions that are checked by the device at each reading gate are defined in the Evaluation conditions group. If defined conditions are fulfilled, specific actions can be performed by the device – for example, setting an output signal, ending a reading gate, or outputting an image or a particular data string. Evaluation conditions can be used to define situations that serve as reference points for flexible process control and data processing in the device software. The use of evaluation conditions shifts the complexity of control tasks from the external controls (PLCs) into the code reader, meaning costs are reduced. General operation Conditions that have already been created can be edited via the opens which specifies the condition in detail. Conditions that have been taught in can be deleted via the button. A dialog box button. A further new condition can be created via the button. A dialog box opens which allows you to accurately specify the condition. The condition type and name are accurately defined in the dialog box along with the condition itself. 8013778/Y269/2013-11-27 © SICK AG · Germany · All rights reserved · Subject to change without notice 79
