  1. Hello there! Maybe my question will be more clear if i will describe the system's configuration. There are 20 plc Premium TSX P57 353 that are linked together over modbus plus with TSX MBP 100 MODBUS+PCMCIA CARDS. When i want to find out what is going on in the program of the 10's plc, i have to open the program of the controller in PL7 pro v4.4 and connect my programming device with PLC's TER or AUX port using TSXPCX1031 cable. Then i press PLC Connect button in PL7 and my programming device is in ON LINE mode. That works fine! But, when i want to connect to another PLC, i have to connect TSXPCX1031 cable to another port as well. lyrical digression: when i have two or more QUANTUM PLC linked together over Modbus Plus i can choose the PLC i want to connect to using Concept interface. I have no need to make some extra physical communications. The question is: Can my Programming device communicate with Premium PLC over modbus plus if my programming device is equipped with 416NHM30030 card? Or: Can my Programming device communicate with Premium PLC over modbus plus if my programming device is connected to TER or AUX port of the PLC and i want to establish communication with another PLC. Thank you!
  2. Hello. I am here again, just to say, that i have solved my little problem. The software i use: - Concept 2.6 XL EN - MBX Driver Suite Version 4.20 for Windows® NT/9x - Visual Studio Net 2003 - Modbus Plus DOS driver for SA85 adapter (http://www.download.schneider-electric.com/C1257307002C03A4/All/852566B70073220C85256969006ECA9C/$File/043510798%20mbplus%20dos%20drvr.zip) this is the examples of the sourse files in C language. They are rather old and will not help you to write 32-bit application, only for 16-bit applications. - Borland C 5.01 for compiling 16-bit source files from Modbus Plus DOS driver for SA85 adapter. - 32-bit Netlib.lib library for compiling application with a 32-bit C compiler. I did not managed to get "The 32-bit Modbus Plus Software Development Kit (SDK)". It is available from www.cyberlogic.com for 1000$. The main problem for me was to obtain a 32-bit Netlib.lib Netlib.h and netbios.h. I found them in "MBX Driver Suite Version 4.20 for Windows® NT/9x". They are placed in ...\MB+\4.20\Legacy\v2xx\WinNT\Lnetlib\DEMO\ and looked like NETLIB.LI_ NETLIB.H_ NETBIOS.H_. All you have to do, to obtain normal files, is to expand them. So, now i cat READ and WRITE holding registers, input and output coils from PC to PLC using my own application spending no money for obtaining OPC SERVERS, Modbus Plus ActiveX Controls or SCADA. Additional information can be found in: - IBMHost.pdf - WINNT.pdf If you have questions- ask me here, or send me eMail.
  3. Thank you aggattapauer, for your advice! I do understand what are you written about I have a lot of free time to learn C or C++, but i have no possibility to purchase two converters RS485<-->RS232... Any way the problem still remains the same: -read data from S400 using VB or C or C++ or another programming language. -write data to quantum (434 12A) using VB or C or C++ or another programming language. -read data from quantum (434 12A) using VB or C or C++ or another programming language. -write data to S400 using VB or C or C++ or another programming language. The way it should be done: is to use NO OPC servers or other SCADA. Only libraries are permitted Any kind of libraries... Thank you!
  4. Well. Ok. The PLC i do use, is quantum (CPU 434 12A) and (416NHM30030) PC card to communicate with it. The main progect is written in Concept 2.6 XL EN. The program is written in FBD language. Why mb+? That is because of the 416NHM30030 card is already installed in PC, and the distance between PLC and PC is more then RTU can provide(It is 20 metres). I need to represent information that i wish to read from PLC in the PC, and write that information to database. As for me MBPLUS.dll is very old, but i can not find another that is younger Well! What is it for? Not so long ago mine Siemens ASi module was broken and there was no other to substitute with. So there was an idea to make a bridge PROFIBUS vs. MB+ to provide the broken sistem with necessary amount of Digital IO. I can read and write data from s400 to PC using libnodave and Visual basic but i can not read or write data from quantum that way I know that is possible to do without any SCADA or OPC. Have an idea?
  5. Hello everybody I am sorry for my english, but i hope you will understand what i am talking about. I want to read and write data from PLC (quantum) to a computer using dll library mbplus.dll, like i can do it with libnodave.dll in Siemens s300 or s400 PLC. It is starnge but i can find no information about doing this with modicon, while i found a lot of information for the siemens! The one of the problems is, that i am not only bad in english, but i am bad in programming too. So i need a programming example how to program my aplication. If anybody can help me with this i will be very thankful! A few month earlier i programmed ADVANTECH PCL-722 card(this is 144 digital IO) in the same way(using examples and dll library) and i had no problems with it. Please dont tell me about OPC client and OPC server Thank you!
