  1. FX 3GEwith GXworks 2

    That isn't really how ladder logic works, it doesn't really do 'else' unless as suggested you go for a PLC with structured text (ST) language option. In ladder one options would be:   IF --[> DB*** DB###]------------------------------------(M1)--- THEN --|M1|-------------------------------------------------(Y0)----- ELSE --|/ M1|------------------------------------------------(Y1)-----    
  2. GOT2000 GD registers

    Thanks for the useful info.
  3. GOT2000 GD registers

    Can the contents of GOT2000 internal registers be retained after power down / power up? Also,and possible related, how do I get a bettery low warning? Finally, what are VGD registers? I've tried the manuals and can't find anything, apologies for such basic questions.
  4. GOT2000 GD registers

    Thanks for confirming my suspicions. Battery low from the HMI, but it looks like that  isn't the issue if the GDs aren't retained. Strangley this PLC has no retentive registers. It has some flash memory you can write to with a special function but that is a bit risky given the possible number of writes. I will use some external memory and a recipe. Webpages? Sounds like too much hard work.  Is VNC free on GOTs yet? 
  5. GOT2000 Modbus Client

    Has anyone used a GOT2000 as a Modbus TCP client over ethernet? I have a Modbus server which works with an e-series HMI and also with PC modbus polling software. I can not get the GOT2000 to even look like it is trying - nothing vaguely modbus in wireshark.     Edit : I can connect to a simulated server on my PC by disabling the firewall so there is hope!   Edit no.2 :  OK, so I have it working but there is over a second delay when updating a value to it appearing on screen. Strange.    
  6. Which software for what PLC?

    Hello All, Is there a table which shows which software will program which Siemens PLCs? I will, of course, be contacting the distributor, I just wanted to be forearmed. Thanks.
  7. GOT GS2110 ethernet connection with robot

    One FX3U-ENET +  an ethernet hub should work.   
  8. GOT GS2110 ethernet connection with robot

    In that case you'll probably have more luck going  [HMI] ---ethernet---[PLC]---ethernet---[robot]  
  9. FX2N 4AD-TC Resolution

    What settings have you used? Type K or J thermocouple? Are you reading from buffer memory 5 to 8 or 9 to 12? Can you post some code?   From the manual: Buffer Memory BFMs #9 to #12 and #17 to #20: Present temperature These BFMs store the present value of the input data. This value is stored in units of 0.1°C or 0.1°F, but the resolution is only 0.4°C or 0.72°F for Type K and 0.3°C or 0.54°F for Type J   The manual for this one is actuall quite good.
  10. Block Compare Instruction

    Then make a function block or use a for-next loop? Or use 1000 lines of code?   Do you want to use 1000 compares???  :)      
  11. Block Compare Instruction

    Or just use 16 lines of code until something better comes along.   Simple and easy to read.  
  12. Safety controller

    Thanks.  Yes, I have seen distributed systems with remote intelligent units (ie networked), some that seem to be a ring configuration and some that seem to be star. All with pluses and minuses.   
  13. Safety controller

    Does anyone have any experience with programmable or networked safety circuits. Does anything stand out as better than the rest? I have some experience with a couple of options but don't want to muddy the waters by giving my opinions first.  
  14. Safety controller

    Thanks, I'll take a look.  Is it just the software that marks it out? Does it have any higher communication to talk to a PLC?  
  15. GOT2000 GT Designer3

    I have the same issue.   Trying to change the background colour on a GT2103 without having to change screen. Currently I just have copies of the same screen with different background colours and switch screens in the PLC as required.  
  16. FX2N-TC

    Thanks for the information.  I've not seen those before.  
  17. FX2N-TC

    What do you mean by "double type" PT100?
  18. what is M code used for in QD75MH2?

    I think I may have misinformed you.  The M code may be written to a data register.  I'll dig out an old program and verify this.  
  19. what is M code used for in QD75MH2?

    It is just set in the PLC if I recall correctly, so if you set it to be M700 the just check the status of M700.  
  20. Sub-contract it out.  Motion can be really quick and simple if you know it well but the learning curve is steep.  
  21. what is M code used for in QD75MH2?

    Data No. are commands to the servo drive? M codes are a "reply" from the servo controller that are on either during or on completion of a positioning event, depending on the set-up.
  22. QJC24SerialInverter_GW2_V100 Library Channel1

    Hi Gambit, The Mitsubishi website is still on version 1.00. Can I trouble you to send me the update?      
  23. Hello all,   I'm using  I'm using QJC24SerialInverter_GW2_V100 library with GX works 2. When I use the function blocks for channel 2 all is well. When I use the function blocks for channel 1 I get an error which points to the following datatype in function block QJC24NoProtocolCh1_FR : CSET_C24_FR. I am assuming that this is a user defined datatype that should be in the library but I an at a loss to work out how to make it work.   Has anyone successfully compiled this channel 1 function blocks?  How?   Thanks.
  24. QJC24SerialInverter_GW2_V100 Library Channel1

    Do you know when the official update will be up?   There is no rush at the moment so I'll try not to trouble you, but thanks for the offer!
