  1. S5 STL to ladder question

    Hi, I have the following STL code in an old S5 processor, can someone tell me if I've transcribed it to ladder correctly please? :O    F11.0 :O    F11.1 :(    I81.6 :AN    F11.2 :AN    F11.2 :O    I81.6 :A    Q64.3 :) :A    I64.6 :A    I64.0 :AN    F3.6 :=    Q64.3 F11.0    I81.6   F11.2   F11.3    I64.6    I64.0    F3.6                  Q64.3 [ ]---------[ ]-----[/]---------[/]--------[ ]--------[ ]-------[/]-------------------( )           |         |                         | F11.1 |         |  I81.6    Q64.3 | [ ]------          ---[ ]------[ ]-------   Thanks in advance
  2. DH485 RJ45 switch or hub

    I have connected 2 dtam units to one slc 5/03 with an rj11 (I think) splitter.  You might be able to use this as a method but I have not ever attempted this.
  3. old software needed

    Have a word with your local vendor about logic master 90, it's also bundled on the versapro and profiecy software disks I think.  Get a trial copy of either.
  4. TSX 47-30 Memory fault LED

    Probably lost the program, but also watch out for faulty PSU AND lost program.  If it was a black tab on memory module that would be a eeprom module but as it is a red one it will drop it's program.
  5. Messaging a PLC 2 over a 1756 DHRIO connection with an L81E

    Not sure this is possible with the CLX, I think your PLC2 needs to be on DH+    
  6. 1747 - L532C SLC 5/03 fault

    If you haven't removed the memory module I've had this when the power supply is faulty.  It powered up (there was a slight delay noticeable) but it dumped the program.  Changing the psu fixed the issue. Of course the memory module could be faulty also.
  7. What is wrong with this SFC

    Have a look at the TONR instruction
  8. What is wrong with this SFC

    Step 0 is set to a type N - non-stored which means the code in the step is continually scanned, so every time you set BACKWASH_START_PB to a 1 the code in step 0 sets it back to a zero.  If you click the square box next to the N you can set the Qualifier to Pulse (Rising Edge) which means the code in step 0 will only be scanned on the rising edge of the step becoming true.  
  9. Thanks for the info, I sorted it out this morning. The software is XBT L100 which runs on a windows 98 machine (in dos mode), its downloadable from the Schneider website.  The cable is: 2-2, 3-3, 5-7 plus 6+4 linked, 7+8 linked at the 9 pin (pc) end. As you say its well obsolete but the client had purchased a spare from ebay and I needed to get the program from another unit to download into this one.
  10. Can anyone tell me what programming software is used on one of these terminals and also if there is a special cable required.
  11. Fault Code 80

    You need a rung in your ladder program to put the devicenet module in run, download the manual from ab.com.
  12. RS Logix v. 20.04

    The firmware does not need changing in the plc when upgrading to 20.04 from 20.01 or 20.03  
  13. S7 300 capturing a short duration input

    I need to catch an input changing state which has a very short duration and I'm currently missing it due to scan time.  Is there a way in Siemens to improve the chances of catching a change by programming e.g. using something similar to a Selectable timed interrupt (STI) from the Allen-Bradley world or maybe a FAST TASK? Thanks in advance for any suggestions  
  14. GOT GS2107 List Selector

    OK thanks, I'll use a couple of momentary buttons to increment/decrement D0 in the PLC
  15. GOT GS2107 List Selector

    Hi, I'm replacing a system I did 10 years ago with Allen-Bradley with a new Mitsubishi system using a GOT hmi.  I'm basically recreating what I did previously so the operators don't have to learn something new.  In the old system I had a list selector where the operator would use arrow keys to scroll down the list of tanks (e.g. Tank A, Tank B etc etc) to select the destination tank, this would return a number to the PLC which would then open the appropriate valve for that tank.  I can't seem to find anything like that in the Mitsubishi software (GT Designer3), can it be done?
