  1. When trying to communicate over a serial port I get "port settings conflict" error in the MAX. After selecting the correct serial settings (57600 Baud, 8bits, no parity 1 stop bit) and saving the port settings the device still doesn't working correctly. As I open a VISA session in MAX I see in the "View all settable Atributtes...." that the baudrate did not changed to 57600 Baud. Only when writing in the VISA session the correct baudrate with the property node (write) the communication for that session works. However when refreshing the MAX or leaving the MAX the settings are changed back to 9600 baud. When programming in LabVIEW I can't get a reply back. It looks like that the application uses the wrong baudrate. (Used several examples from NI where baudrate is configured.) Does some one encounderd this problems before and is there a work arround for it? I'm using LabVIEW 8.5 MAX 4.2.1.3001 NI-VISA 3.1 Hope someone could help me Theo
  2. I have some questions concerning Profibus communication between a Compact Field Point system and a Siemens PLC. The following hardware is used: NI cFP 2120 controller Siemens S7 314 MPI Has somebody tried to read data from a Siemens PLC over the RS485 ports with profibus? If yes, could we get the (Siemens) command set so we can try to retrieve data from the PLC (using NI-VISA). Or has somebody already programmed a solution, could we then have an example of how it has been programmed. Has somebody solved this problem of communication in a different way? What was the solution and how much time / money did it take. Hope someone could help me with this problem. Already thanks for the effort.
  3. In this case I want to decrease the footers height. I already tried to decrease the margins of the page, this helped a bit but not enough. Maybe I should use a word template instead of programmaticaly change the height.
  4. Indeed there are lots of usefull Vi's in the addons library but not one to change the hight of the footer. I've only looked shortley at the msdn website but did not found anything in the short time I had. Still hopes that someone has an example or detailed description with activeX. Thanks for the reply Theo
  5. How can I programmatically change the hight of the footer in a word document. Do I have to use a property node or can I use the report generation toolkit. I'm still using labview 7.1 on a windows 2000 platform (2000 office) Theo
  6. An extra thing I miss here is the Ctrl + E to switch between Block diagram and front panel :thumbup:
  7. Hi, Is it possible to use the NI service locator in a VI. :question: If this is possible how should I go to work and is it possible to tell the Ni service manager not to use certain port numbers. Hope someone could help me Theo
  8. Thnx mballa with the monoitor I found out there was a non printable character. With the character the program works fine now. greetings Theo :thumbup:
  9. Hi, we use LabView to automate Test and Measurement equipment. We are working for all kind off industries and universitys.
  10. Accordingly to the manual the carriage return and line feed are optional. theo
  11. Hi there, I need some help!!! I want to read a displacementsensor through serial communication. But i get a timeout error when the Visa is sending the string to the displacement sensor. I've tried to enlarge the timeout with a property node. Still no result. The string I'm sending is correct because it works if I use program hyperterminal to communicate with the sensor. Please HELP somebody, I am probably doing something wrong and can figure it out. :headbang: The VI is attached. The error will occur in the VISA write (error 1073807339) THNX Download File:post-1757-1112791619.vi
  12. Hi Karthik, there is a possibility to do this with a statemachine. I've included an example with three buttons. Hope it's helpfull for you. Greetings Theo Download File:post-1757-1112169298.vi
