  1. Siemens FB900 ModbusPN

    Whilst using the Siemens ModbusPN and associated Modbus_Param DB how do you get the 8 different modbus Data Areas (Data_Typ, DB, Start_addr, End_Addr) "to connect" to FB900    
  2. FX3U (le3u) countdown timer?

    This may help- However you may have to create a 1 minute pulse and count up to your required time - 13hrs = 780 minutes etc
  3. S7-200 Smart Analaog input problem

    All the information is contained  in the S7-200 Smart System manual. Possible faults are = loss of 24V DC, Overflow or undeflow ?? But checkout the manual sections C & D for diagnostic information.  
  4. 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?
  5. 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

  8. 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
  9. DB vs PLC Tags

    this may help - (for use in a "class" on the differences but may be worth a read?)
  10. S7-1200 timer

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

    What HMI ? What version of S7
  12. 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"
  13. 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.  
  14. 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)
  15. Hundreds of Discrete Alarms - Simplest method?

    I had the same problem recently swapping from Omron to S7 - still fresh in my mind.
