  1. String Value convert to date format

    I'm assuming this is a real value and is a time format starting from 1900  excel uses this same thing put that number in excel reformat to time with date and you get your number  so start doing a little math  43865.7090393519 43865 days from 1900 .7090393519 of the current day so 24*.7090393519=17.0169444456‬ so then 17 hours into the day then keep going with now the decimal left is what part of the hour is left  when your done you should get  2/4/20 5:01 PM Dont forget about leap years this could get interesting 
  2. 1769-L32E Need t2 ethernet ports

    One thing your gonna do with default setting is cause the ethernet switch to lock up with to much traffic  if you go under processor advanced tab and change setting concerning system overhead time slice by default will be 20% and when we have overhead time what do you want to do once again default is perform more ladder change that to perform communications and you might want to increase the 20% to more if you can give up scan times for your process  
  3. Anyone familiar with two speed crane buttons I assume that when you push the button down a little bit it closes the first set of contacts and if you want to go faster you then push the button all the way down causing another set of contacts to close so in high speed we have both sets of contacts closed?   Thank you
  4. Clearing an Array in RSLogix

    I'm sure this is not the smoothest way to do this but  I would use indirect addressing and when I push the clear button the index counter will scroll through the tags one scan at a time every scan add one to the Indexing_Counter till it reaches 20 then stop adding to Indexing_Counter            
  5. ControlLogix Controller & Program tags

    How I would accomplish this is to rename the existing tags slightly then create a new controller tag named correctly and use the new tag in code once the old program tag is no longer in use you can delete it  It is possible to address your scada system to look at program tags example is  Program:<Program Name>.Tagname  but you will have to research your scada how to address

    Hello Currently have no way to open the code but I believe this has an example of how to send a text message from PLC   090414.RSS
  7. Proficy Machine Edition 9.5

    Will this software suite upload a program from a  series 90 micro plc programmed in 1999 I have no idea what suite of software programmed it I just know that I couldn't upload code from it kept getting error of  the selected memory couldn't be uploaded from the connected device is that because of a password or program was written in a suite that isn't supported by Proficy 9.5? I don't need to upload as I rewrote the code and got it going but there are 30 more and would like to know my options for moving the customer forward. thanks I'm sorry for asking some basic questions to you GE guys but geographically we never see a GE until I found these or they found me  thanks for looking
  8. Code Conversion

    The new cable works great but I'm getting an error  "the selected memory couldn't be uploaded from the connected device" then it kicks me off I can upload the hardware, and I/O tables But no ladder  Now that I'm sitting in my easy chair and looking I may have messed up  I made a new project in Proficy and may have had the wrong processor in the project when I was trying to upload? \ Looking for some ideas to try or if I have to find some legacy software thanks alot 
  9. Code Conversion

    Old series 90 micro with 15 pin can you convert the ladder logic to a versamax with rj45 programming port using proficy machine edition Plc cable for 90 micro will show up Saturday delivery and have to travel to remote location and have zero GE experience  Looking for some advice managed to get familiar with software and got code uploaded from versamax so was hoping to change processor or copy and paste logic only 35 rungs so could rebuild by hand if necessary  thanks for taking time to read 
  10. ML1400 Heartbeat

    My current method is almost the same as Jeremy's except i use the internal free running clock in PLC A My old method is put bit high in PLC A then in PLC B turn it off when on and start a timer this works fine for proving communications but doesn't prove that PLC A is healthy.
