어떠한 콘트롤러도 통신할 수 있다?

• Multi-DNC™의 원격 기능

원격 모드는 Multi-DNC의 가장 유용한 기능 중의 하나이다. 원격은 사용자가 CNC 컨트롤러로부터 DNC 컴퓨터로 걸어 가지 않고 직접 기능을 지령하고 "드립 피이드" DNC 통신을 구동하고, 송.수신을 CNC 운영자에게 허용한다. 사용자의 CAM 프로그래머는 CAD/CAM 워크스테이션으로부터 CNC 프로그램을 송신 또는 수신하거나 테이프에 대한 요청을 CNC 프로그래머에 의해 방해 받지 않는다. 많은 양의 시간이 프로그래머와 CNC 운영자에게 둘 다 절약될 수 있다. Multi-DNC에서는, 콘트롤러 그 자체에서 모든 작업을 하기 때문에 CNC 콘트로에 의해 여분의 터미널이 필요하지 않다!

기계 연결이 원격 모드 일 때, COM 포트는 요청 파일의 합법적 파일명에 연계되어 문자의 "스트링" 또는 어떤 시퀜스에 대한 "스캔"으로 설정된다. 이 문자의 특별한 스트링은 단일 요청 프로그램을 찾고 CNC 콘트롤로 전송하거나 몇 개의 다른 기능은 물론 CNC 콘트롤에 전송할 것을 Multi-DNC에 지시한다. 다음 대화 상자에서 원격 파라메터의 모든 것을 설정하고 Multi-DNC 시스템에 각 기계 연결에 대하여 다르게 설정할 수 있다.

• Multi-DNC™로부터 CNC 콘트롤로 파일 수신

원격 모드에서 CNC 컨트롤에 파일을 수신하기 위하여, CNC 운영자가 다음과 같은 두 예제와 같은 작은 프로그램을 생성한다:

• CNC 콘트롤로 디렉토리 리스트 전송

Another feature of Remote is the ability to receive a directory listing at the CNC control of all of the files that are available for downloading. To do this, the CNC operator punches a small program like this:

• "와일드카드(*.*)" 전송 명령 이용하기

• 저장을 위하여 Multi-DNC로 원격 파일 전송

The CNC operator just needs to punch out the program to Multi-DNC in the normal way; if the DNC computer is setup in Remote for that Machine Connection, the Autoname function will automatically name the received file on the DNC computer and save it to the Machine Connection’s Receive folder. The file will be named according to the first comment like this:

• Multi-DNC™로 다른 데이터 전송

Remote can also be used to store other types of data that can be output from CNC controls, such as formatted values output from probing macros or SPC gage output, as long as the data is preceded by the string of characters specified in the Capture section of the Remote dialog. CNC controls that have Macro capability can output text messages in ASCII text form from their RS-232 ports and Spectrum is using this to develop an add-on program for Multi-DNC that will track the usage of multiple CNC machines in a production environment.

• 원격 다시시작 기능

When doing direct (drip feed) DNC operations, the CNC operator can stop the flow of data when a tool breaks, and then send a small program back to Multi-DNC that will command it to "backup" and restart the sending of the file. The Remote Restart request can tell Multi-DNC to backup a given number of lines, backup to an absolute line number, or backup to a "bookmark". A bookmark is a pre-set code in the CNC program, usually at a tool change, where the CNC program could be started over. Your CAM system post processor can be configured to insert this code at each tool change. After Multi-DNC receives the Restart request, it backs up to the requested position, then waits for the CNC operator to hit Cycle Start to begin cutting again.

Because all of the Multi-DNC products have a powerful 32 bit multi-threaded communications "engine" that enables true multi-tasking, any CNC control that is connected can request a file at any time. No switches to change, no tapes to find, no more interruptions of your programmer to get the next job, no more coffee breaks to get a program, and no more yelling across the shop to get a new program. Production shops that may never use the direct DNC (drip feed) mode of communication need Multi-DNC just for Remote. And in fact, over 40% of our customers buy the DNC software just for Remote. If you have any questions regarding Remote or any other of the features of Multi-DNC , please contact Spectrum CNC Technologies for the name of your local representative.

Multi-DNC can now also monitor the running of your machine tools. The goal is to provide simple, yet valuable information in a cost-effective manner. The system is an add-on module to any existing Multi-DNC system and uses the same RS-232 cabling to retrieve data during RS-232 ‘idle’ time. By installing a PLC (4’’x4’’x6’’) with our custom PLC program into the CNC control, we can monitor up to 8 aspects of a machine tool. The PLC accepts 24V DC inputs, which can be directly connected to CNC controls. We have found that we can connect to the machine tool’s I/O terminal strip to monitor such things as ‘In-Cycle’ or ‘In-Alarm’ and by the addition of a 3 position key switch we can also track ‘In Setup’, ‘In Maintenance’ and ‘In Production’ modes.

The application designed for viewing the data retrieved by the monitoring system can be run on any PC which has network access to the main Multi-DNC system. Data is presented in graphical, cumulative time, on/off or count and can be viewed between specified dates. Groups or single machines can be viewed as required and the data can be printed to any printer supported by the operating system.

Events can be created that will call a pager or launch another application when certain criteria are met. For example an e-mail could be sent or a message sent across your network to the appropriate person who can then take the required action.
