HEIDENHAIN iTNC 530 CNC system backup and recovery

The German HEIDENHAIN CNC system is called "BMW" in CNC machine tools with its friendly man-machine interface and practical innovative functions. The HEIDENHAIN iTNC 530 CNC system is a versatile contouring CNC system for milling, drilling, boring and machining center machines from HEIDENHAIN. In addition to the friendly and simple dialog format programming language, the iTNC 530 CNC system has a fully digital design that allows all components to be connected via a pure digital interface with high reliability.
In the equipment management and maintenance practice, like other CNC systems, iTNC 530 can also cause accidental modification or even deletion of machine parameters, PLC programs, NC programs and tool data due to unexpected reasons such as misoperation, thus making the machine tool Some functions are lost or even the whole machine is paralyzed. It is an important task to do a good job of backing up machine data. When the above situation occurs, restoring the backup data can quickly restore the function of the machine. Therefore, mastering the operation methods of data backup and recovery is an indispensable skill for equipment management and maintenance personnel.
1. Establish a connection between your PC and the iTNC 530
The iTNC 530 system can establish a network connection with a personal computer using an Ethernet interface, an RS232 interface, and an RS422 interface. This document discusses the backup and recovery method of the iTNC 530 system using the Ethernet interface. Backing up and restoring the machine data of the iTNC 530 CNC system requires the installation of the HEIDENHAIN transmission software TNCremoNT on the PC. When connecting using the Ethernet interface, use a crossover cable to connect the Ethernet interface of the PC to the X26 Ethernet interface of the iTNC 530. The last segment of the IP address of the personal computer and the iTNC 530 must be different, and the other segments must be the same. According to the relevant information of HEIDENHAIN, it is recommended that the last segment of the personal computer IP address be 1 or 1 larger than the last segment of the iTNC 530 IP address. The subnet mask of the personal computer and the iTNC 530 IP address must be the same. For example, an iTNC 530 system has an IP address of 192.168.10.13, a subnet mask of 255.255.255.0, a personal computer with an IP address of 192.168.10.12, and a subnet mask of 255.255.255.0.
The specific process for establishing an Ethernet connection between a personal computer and the iTNC 530 is as follows:
(1) Turn on the external memory switch of the iTNC 530. After the iTNC 530 CNC system is started, press the MOD function key “MOD” on the display unit, then press the right end of the expansion button and select the “External Storage Switch” horizontal soft key to set it to the “ON” position. This switch is the setting switch for the iTNC 530 to communicate with the outside.
(2) View the IP address and subnet mask of the iTNC 530. Press the “Program Edit” button on the iTNC 530 man-machine interface to enter the file editing page, press the MOD function key “MOD”, enter the password “NET123”, press the Enter key to confirm, and then press the horizontal soft in the new screen. The key "DEFINE NET", you can see the IP address and subnet mask of the iTNC 530. For example, an iTNC 530 system has an IP address of 192.168.10.13 and a subnet mask of 255.255.255.0. This address should be remembered and will be used later.
(3) Ethernet communication settings on the personal computer. Open the control panel on your PC, double-click "Network Connection", right-click "Local Area Connection" in the pop-up "Network Connection" window, click "Properties" in the drop-down menu, in the "Local Area Connection Properties" dialog box that pops up. Select "Internet Protocol (TCP/IP)", click "Properties", select "Use the following IP address" in the "Ieternet Protocol (TCP/IP) Properties" dialog box that opens, and write the individual in the IP address field. The IP address of the computer: 192.168.10.12, the subnet mask column is written to 255.255.255.0, and then click "OK", as shown in Figure 1.

4. Conclusion
Doing a good job of backing up the data of CNC machine tools is an important task that must be done. Mastering the methods of data backup and recovery of CNC machine tools is an indispensable skill for equipment management and maintenance personnel. Not long ago, a WRF160 machining center produced by the Czech company of the company was estimated to have an alarm No. 5338 due to misoperation: the soft key planning was not compiled, and the SPJ file was checked. This alarm caused the machine function to be completely lost. After the PLC file is compiled, the iTNC 530 reports 20 error messages. Locating and processing these 20 error messages may require more specialized knowledge. In the actual processing, the author has restored the data backup of the machine tool that was usually done, and easily restored the functions of the machine tool.
