Hi friends,
Help me to convert from STL to LADD below the statement,

O "M 1226.5" M226.5 -- step 5 length of hood
O "M 1226.6" M226.6 -- step 6 film separators up
O "M 1226.7" M226.7 -- step 7 sealing - cutting
O "M 1227.0" M227.0 -- step 8 pressure arms forward
O "M 1227.1" M227.1 -- step 9 hood over stack
O "M 1227.2" M227.2 -- step 10 start burner
A "M92.7" M92.7 -- double hood
AN M 128.5
AN "M 128.6" M128.6 -- speed change to slow down
JC M007
JU M008
M007: = "M 130.0" M130.0 -- lift speed n11
= "M 130.1" M130.1 -- lift speed n12
= "M 130.2" M130.2 -- lift parameter commutitation
BEU
M008: NOP 0



In future how to convert similar statement,
Got one option there, but some network unable to convert,
On the particular network how will change to LADD,


Thankyou in advance!

If there are NO other jumps to label M007 (that is, M007 is used only twice in the whole block), then this code is equivalent to yours and Step7 can convert it to LAD:
Code: 
//Network1
      A(    
      O     M    226.5
      O     M    226.6
      O     M    226.7
      O     M    227.0
      O     M    227.1
      O     M    227.2
      )     
      A     M     92.7
      AN    M    128.5
      AN    M    128.6
      S     M    130.0
      S     M    130.1
      S     M    130.2
If the network you posted is NOT the last one in the block, you will also need to:
1) define a new Temp variable (Bool datatype)
2) add this line to the end of network I posted (Network1)
Code: 
      =     #YourTempVariable
3) add this network immediately after the network I posted
Code: 
//Network2
      A     #YourTempVariable
      SAVE  
      BEC

If there are two or more jumps to M007 then it may not be so easy to convert to LAD!

If Step7 can't convert the code for you automatically then the most reasonable choise is to learn STL ;)
 
convert STL to LADD,

Hi frd,
Thank you for your reply,
Please refer below my program details,
i need to control the speed of outerhood film,(example network-5)
please advise me some more details for speed control and convert the ladd program,
and how to change,

Thankyou in advance!

It doesn't convert directly to ladder because it was written in STL. Why not try and learn to understand it in STL? You have a series of logic statements (A, O, AN, ON) which each, in turn, contribute to the RLO (Result of Logic Operation) followed by some conditional jumps. If you highlight an instruction and press F1 you will get a description of that instruction from the help system. In status mode you will see the status of each line in the STA column followed by the RLO in the RLO column; in this way you can see what is going on as each instruction is processed.
