    Dynamic object move with feedback

    I use only two symbols to build a valve being either light or dark (red or green) whatever you like then dynamicaly activate to show as on or off. By aranging several of these (like a clover leaf) you can easily make all the various valve types, one way, two way, 3 way etc.

    Printing Documentation Problems

    I quite agree on the PDF as absolutley the most usefull format, no argument there. However my problem is that in many cases the resulting PDF is unreadable. Failing on pagination for longer functions and on width for more complex ladder statements. The is no title field nor any page numbering to pull it all together. I would love to see some way to insert a formfeed in the code giving me a clear sectioning of functions. The poster option doesn't really help all that much and results in something impossible to use in a binder notebook. It may well be that Adobe is not helping much here but it actually can't change the source file.

    Printing Documentation Problems

    I think that Unitronics should put some real effort into this. Good documentation is a major part of good programming. Some control over boarders (top, bottom, left, right) and page numbers would help quite a bit. Print all fails miserably from function to function. Individualy printing each function does work better but takes great effort to get a readable result. That said the screen capture does give a better result quicker than many other plc/panel programs.
  4. I have problems printing program documentation. The program editor print does not seem to handle paging of modules correctly. Short modules are pretty reasonable but longer ones also get printed all on one page. This results in a scaled font of microscopic size which is unreadable. I've tried all the combinations of fit size scale etc. without success. Any tip on how to do a readable document?

    Admin users in UniLogic

    removed everything, rebooted, reinstalled. same problem it is possible to "fix" the SQLserver but it will not stay fixed. a new install of SQLserver checks ok but does not survive a reboot of pc. the unilogic diagnostic is not happy nor is the unilogic.

    Unfortunately diagnosts.exe did not help. The Fix button gets a green check on SQL Server then nothing. Next run of diagnostic shows the same two red crosses, (the fix did not do anything) Unilogic still hangs. Changed the exe and msi to administrator but no help.

    version 1.23.25 hangs after installation. 1 install is ok on a win7 machine. 2 failures, one on a win7 and one on a win 10. I have not yet been asked for the key number. the screen shows "loading components"

    HELP! Newbie to Programming

    yes TD is correct It will be easier for you to read the program if the elapsed timer is connected to a marker flag. then use the flag in other ladder rungs.

    For an explanation of byte/word order take a look at : https://en.wikipedia.org/wiki/Endianness

    Ethernet IP Communications

    Question 2. Look at this a binary to see it better. The representation of the value as decimal, octal, binary has no affect on the result. Your required value determines the number of bits used 4, 8,16, 32, 64 . breaking up words, bytes, bits is done with the Logic And instruction Using a mask like '0000 1111' will remove the bits masked by zero. resulting in only the bits masked with 1's Here the original high part disapears. Getting hold of the high word, byte, bits takes one more operation first mask the high part '1111 0000' then do a Shift Right 4. Giving a result of '0000 1111'. Here the original low part disapears. (Some cpu's allow filling with 1's or 0's when shifting.)
  11. reprogram the magflow for 1000 pulses per m3. if necassary use the high speed counter input. save a copy of counter value every second subtract from previous value copy.
  12. Unilogic won't compile new hardware configuration please look at the enclosed file. it compiles ok before we added local expansion module regards bob

    UniStream--what projects are YOU building?

    Controlling a drying machine on customer site. Communicating via mobil GPRS with ethernet card. Remote operation can be greatly improved.

    Beginner Ladder Programming Question

    The trick here is to write your program in steps using MB as flags. step1 = NOT step2 then set step1 flag (turn on valve output) step2 = NOT step3 and step1 and low pressure set step2 flag (turn off valve) Each network should start with a NOT contact of the next flag plus an AND of the previous flag, thus blocking an unwanted sequence. Make a program routine just for the steps Make an output routine which ties the flags to the outputs. Make a reset routine to clear all the flags.
  15. Hi, I'm trying to make connection to a V570 over internet. The connection works ok on the local network internally, but not from the internet externally. I open for port forward of TCP port 20256. Other products do work ok with the same type setup using the router public IP. My concern it that the router does not see the V570 at all it doe not show up on the connection list. I can ping it, but port forward doesn't seem to find it. This is an Option Globe Surfer III. I have used this with pc to pc connections on site ok. Does anyone have a suggestion or perhaps another modem that works with Unitronics?
