Telemecanique Instruction set

Hi All
We have an old Telemecanique TSX-47 PLC and are currently looking into converting it to AB, as that is now our site standard. The problem is we only have a printed copy of the ladder and no one is familiar with the instruction set.

Does anyone know what the following mean/are

  +----COMPAR----+

 -|C1,V >= 150   |-

  +--------------+



  R+---C1----+E

 --|         |--

  P|         |D

 --|         |--

  U| C,P: 0  |F

 --| MODIF: Y|--

  D|         |

 --|         |

   +---------+





  +------OPERATE-------+

  |W46  + 1 -> W46     |

  +--------------------+



  R+---D6----+F

 --|         |--

   |         |

   | TB:100ms|

  U|         |

 --| LEN: 6  |

   |         |

   |         |

   +---------+



  +------OPERATE-------+

  |4  -> D6,s          |

  +--------------------+

Thanks

Hi Jezz

1. Compare Block
This will act as 'NO contact' and be a logic 1 when counter 1 (C1)actual vaue is greater than 150

2. Counter
Up/down counter:
R= reset
P= load preset
U= count up (rising edge)
D= count down (rising edge)
E= empty (underflow)
D= done (preset reached)
F= full (overflow)

3. Operate Block
In this case is incrementing internal register W46. (W46 +1 then transfer value back into W46). Should have one shot contact somewhere in control line or it'll do it every scan.

4. Drum Controller
R= reset to step 0
U= advance a step (rising edge)
F= full (on last step defined)
TB= time base
LEN= no of steps defined

5. Operate block
This is forcing drum controller D6 to step 4
