Read Heidenhain Part Counter Data (PDF 254KB).Output section = 0 FIG 5: Activate acquisition of Heidenhain part counterįor testing you can also use the Heidenhain PLC utility program and query the respective addresses. Also make sure that CollectCounters = 1 in CNCnetPDM.ini. To activate counting edit the file with a text editor, set Active = 1 and adjust Input parameter 1 according to your controller type, 20 for TNC 426, 430 and iTNC 530, 10 for TNC 320, 620 and 640. heidenhain_1000.ini for machine number 1000.įor counting workpieces section of this file is used. Reading of part counts with CNCnetPDM can be controlled by using the INI file which is automatically created for every connected machine e.g. To count parts you simply have to add one line to every NC Program before its end that calls the above program e.g.ġ1 END PGM FELGE_MILL MM FIG 4: Call Heidenhain part counter NC Program TOP READ COUNTER DATA Note: Please select only one version of line 2 according to your controller type.ġ FN 1: Q48 =+Q48 + +1 Increase Q48 by 1Ģ FN 17: SYSWRITE ID 2000 NR70 IDX20 =+Q48 Write Q48 to PLC Workpiece Counter W20 iTNC 530Ģ FN 17: SYSWRITE ID 2000 NR70 IDX10 =+Q48 Write Q48 to PLC Workpiece Counter W10 TNC 640ģ END PGM COUNTPART MM FIG 3: Heidenhain part counter NC Program.Write a small utility program, here COUNTPART, that maintains parameter Q48 and updates the respective PLC Address value. To acquire part counter data you have to utilize an unused Q-Parameter that is not reset automatically, preferably between Q20 and Q99. TOPįIG 2: Heidenhain PLC workpiece counter (TNC 640) ACQUIRE PART COUNTS Newer NCK based controls like TNC 320, 620 and 640 use PLC Word Address 10. For TNC 426, 430 and iTNC 530 devices PLC Word Address 20 is used. Storage is performed by the machine’s Programmable Logic Controller (PLC). Heidenhain controllers have the ability to display and store workpiece counters. TECHNICAL BACKGROUND | ACQUIRE PART COUNTS | READ COUNTER DATAįIG 1: Part counter output (Heidenhain TNC 640) TECHNICAL BACKGROUND For machines equipped with Heidenhain TNC and iTNC controllers CNCnetPDM enables to automatically acquire part counter data without any user action required. For any kind of performance-, OEE- or cycle-related analysis of machine data information about the number of produced workpieces is required.
