1 CNCC6/C64 PLC PROGRAMMING MANUAL (Ladder Section with MELSEC Tool)BNP-B2309D(ENG) MELSEC and MELDAS are the registered trademarks of MITSUBISHI ELECTRIC Corporation. Microsoft, Windows and Microsoft Windows NT are the registered trademarks of Microsoft Corporation in the United States and/or other countries. Other company and product names herein may be the trademarks or registered trademarks of their respective owners. i Introduction These specifications are the PROGRAMMING MANUAL used when creating the sequence program with the PLC development software, or MITSUBISHI ELECTRIC Co. s integrated FA software MELSOFT series (GX Developer). The PLC ( programmable logic controller ) is largely divided into the basic commands, function commands and exclusive commands, and ample command types are available. The commands can be used according to the purpose and application such as the PLC support function used when supporting the user PLCs.

2 In addition to the explanation of commands and functions, the environment to develop the user PLC using GX Developer, especially the usage unique to MELDAS, is described. CAUTION For items described as "Restrictions" or "Usable State" in this MANUAL , the instruction MANUAL issued by the machine manufacturer takes precedence over this MANUAL . An effort has been made to describe special handling of this machine, but items that are not described must be interpreted as "not possible". This MANUAL is written on the assumption that all option functions are added. Refer to the specifications issued by the machine manufacturer before starting use. Refer to the Instruction MANUAL issued by each machine manufacturer for details on each machine tool. Some screens and functions may differ or some functions may not be usable depending on the NC version. Refer to the related operation manuals for details of GX Developer and GX Converter usage.

3 [Documents relating to MELDAS C6/C64] MELDAS C6/C64/C64T PLC Interface BNP-B2261 MELDAS C6/C64 Network BNP-B2373 ii Precautions for Safety Always read the specifications issued by the machine manufacturer, this MANUAL , related manuals and attached documents before installation, operation, PROGRAMMING , maintenance or inspection to ensure correct use. Understand this numerical controller , safety items and cautions before using the unit. This MANUAL ranks the safety precautions into "DANGER", "WARNING" and "CAUTION". When there is a great risk that the user could be subject to fatalities or serious injuries if handling is mistaken. When the user could be subject to fatalities or serious injuries if handling is mistaken. When the user could be subject to injuries or when physical damage could occur if handling is mistaken. Note that even items ranked as " CAUTION", may lead to major results depending on the situation.

4 In any case, important information that must always be observed is described. DANGER Not applicable in this MANUAL . WARNING Not applicable in this MANUAL . CAUTION 1. Items related to product and MANUAL For items described as "Restrictions" or "Usable State" in this MANUAL , the instruction MANUAL issued by the machine manufacturer takes precedence over this MANUAL . An effort has been made to describe special handling of this machine, but items that are not described must be interpreted as "not possible". This MANUAL is written on the assumption that all option functions are added. Refer to the specifications issued by the machine manufacturer before starting use. Refer to the Instruction MANUAL issued by each machine manufacturer for details on each machine tool. Some screens and functions may differ or some functions may not be usable depending on the NC version.

5 2. Items related to start up and maintenance Read this MANUAL carefully and confirm the safety enough before executing the operation of the program change, forced output, RUN, STOP, etc. during operation. Operation mistakes may cause damage of the machine and accidents. DANGER WARNING CAUTIONiii CAUTION 3. Items related to program development Always observe the cautions before development to develop a program. If the data transferred does not follow the file name rule, the CNC will mistake it for another data, resulting in unexpected operation, PLC program erasure. Do not read a sequence program on which a conversion error occurred into the GX Developer. The file may include unexpected contents to result an illegal operation. When an error occurred at GX Developer On-line function, the error message may not explain exactly the state in the CNC side.

6 Always refer to the error list. When initializing PLC data storage area is performed, all sequence programs and messages currently stored in the CNC will be erased. Do not use this operation other than when the error cannot be solved. iv Contents 1.
