  1. FX3U (le3u) countdown timer?

    This may help- https://www.youtube.com/watch?v=RYC5t6GoeGQ However you may have to create a 1 minute pulse and count up to your required time - 13hrs = 780 minutes etc
  2. S7-200 Smart Analaog input problem

    All the information is contained  in the S7-200 Smart System manual. https://support.industry.siemens.com/cs/document/109745610/s7-200-smart-system-manual-?dti=0&lc=en-CN Possible faults are = loss of 24V DC, Overflow or undeflow ?? But checkout the manual sections C & D for diagnostic information.  
  3. Non siemens hardware commuincation over profibus

    I cannot say without the manual for your particular device - but in most cases yes it should. Can you post a link for the manual?
  4. Non siemens hardware commuincation over profibus

    Have you set the profibus address on the gauge? The user manual will show what bits/bytes/words etc are for reading and writting to the device

  7. S7 Classic SCL

    I needed a shift register for S7 Classic and after a lot of searching I wrote my own in SCL. First time writing SCL Code - so would someone like to test ("to destruction" )the attached SCL Code for me? Hopefully the comments make sense and it does seem to do what I want. The zip file contains a S7 libary of the block (FB207) as well as the SCL Code and a text document Thanks in advance   Description.zip
  8. DB vs PLC Tags

    this may help - (for use in a "class" on the differences but may be worth a read?) https://www.industry.usa.siemens.com/automation/us/en/formsdocs/Documents/2016%20MIA-%2056%20Rockwell%20to%20Siemens%20TIA%20Portal.pdf
  9. S7-1200 timer

    Do not use "Local Data" use "Global Memory instead" - ie use %M1.0
  10. CP 343-1

    What HMI ? What version of S7
  11. Can someone please help me finding this tag?

    The "tag" you have indicated is only used within the FC (internal Parameter). have a look at where your FC is used (FC207) and you will see the actual parameter that is passed to the "internal parameter"
  12. Vipa CPU 315SB-2AG12

    Has anyone experience connecting to a Vipa  315SB 2AG12 CPU with Simatic Manager? I have tried the Siemens USB PC adaptor and cannot connect - any help would be appreciated. Thanks in advance.  
  13. TIA TP1500

    Normally ## will appear if there is no communication OR the configured field is not long enough to display the variable. (ie the field is configured for 3 "places" but the value is 4 "places" long)
  14. Hundreds of Discrete Alarms - Simplest method?

    I had the same problem recently swapping from Omron to S7 - still fresh in my mind.
  15. Hundreds of Discrete Alarms - Simplest method?

    Over writting of address !!! I think you mean -  Alarm Word 1 = MW100 Alarm Word 2 = MW 102 Alarm Word 3 = MW104 Or use a Data Block.
