  1. Hello everybody, i have some uncertainties going through my head. i am fairly new in PLC word, graduated last year, last 12 month i did project on Siemens PLCs, but now i have to expand my view with Mitsubishi. 1. i am working on project with several conveyors. for each conveyor type i have FB fairly similar to my FB in siemens. For all conveyor i am using same sdt containing 32 bits. So a have array[0..20]  of said sdt. But in fb i was not able to copy item from array, through input var containing index of that item to vocal variable, which i wanted to write back to the array at the end of fb. I tried different approach ->  using item from array *** input/output.  When monitoring item from array i can see, that variables i change in got2000 panel are in fact changing. But when i monitor fb itself, those same variables are not changing. i reworked this fb several times, for example when i found out that FB variables FB FXcpu cannot be set as retain so i would like to use it and i see no other way than make this fb work. :D 2. Is there possibility to us FB in another FB? I remember that i read some restriction about this, but now, i cannot find it. Thank you everybody for your responses    
  2. Hello from korea :)   actually i am new to company which i do freelancer job and i am not used to dealing machine with sysmac studio its hard to make things perfect...   its just simple thing move servo motor.. you can check my situation more closer if u see the picture that i uploaded   i think control servo motor By function named MC_MoveAbsolute4(Axis,execute, parameters......) i just use that function by put them in while loop so that i can check the move of motor but nothing happen lol   What can i do!
  3. RSLogix5000 Transfer function Bumpless transfer between two inputs. If criteria or FLAG is true, then transfer from input-1 to input-2 at a prescribed ramp rate, and then release the output to match the selected input without rate restrictions.  Issue: The issue is that upon the status of particular input (FLAG), the control valve demand jumps from 0 to whatever the output of the PID’s Low Select value is (maybe 50% or 80% or other). Request: Ideally, I would like to mimic or replicate the Transfer algorithms provided in other control systems, as described below . The TRANSFER algorithm performs a transfer between the two inputs.  The output is equal to the IN2 input if the digital input FLAG is TRUE, and the IN1 input if the digital input FLAG is FALSE.  The algorithm automatically performs a bumpless transfer between the track input and the selected input when a tracking request is removed.  The algorithm ramps to the selected input (IN1 or IN2) at the specified track ramp rate (TRR1 or TRR2).  Internal tracking may be selected to allow a bumpless transfer between IN1 and the IN2 inputs.  Individual track ramp rates may be initialized to ramp from the IN1 to the IN2 and from the IN2 to the IN1. Attached is RSLogix5000 program "transfer.acd" Thanks.
  4. Allen bradley Micro850

    Hello, I am new to automation and I do a project with a Micro850 Plc. I am more comfortable with logic block so I write my program in Function Block langage on Connected Component Workbench software version 12. I would like to make flashing a light but I don't know wich block to use and how to program it ... Could you help me. Thank you
  5. Hello, In past i was using Siemens S7 300 and Simatic 5.3. So a long time ago. I restart look back to plc because i need to monitor the temperature of my heating system. So bought a plc that is a IEC61131-3 standard and  OpenPCS as Develop software.  So i begin to play with OpenPCS because  Im very rusty.  SO i create a function, that i named FC_TEST . When i compile the below code i get an error E: S5004: Function blocks instances are invalid in 'FUNCTION'-POUs, STRUCTs, and in ARRAYs.  It seams that Timer block inside the function FC_TEST are not allowed, i understood right ? (*  --------- DECLARATION  ---------  *) VAR_INPUT T_1 : TIME ; (*Declare T_1 as a Time Input ==> Set the Time of Timer *) START : BOOL; (*Declare START ad BOOL Input ==> Start The Time of the TIMER *) END_VAR VAR MY_TON : TON; (*Instantiate MY_TON as Timer type TON*)  END_VAR (*  --------- FC PROGRAM  ---------  *) MY_TON(IN := START , PT := T_1 ); FC_TEST := MY_TON.Q;   (*  --------- CALL THE FC---------  *) tmp2 := FC_TEST(T#2s, I0_0);  (* I0_0 is a input*) Thanks  Marco

  7. GXWorks 2 Comment Translation

    Hello, I was wondering if any of you have experience translating comments. To be more specific, I have been tasked with translating all of the comments in my plant from japanese to english. We have many different series of PLCs, but they are all mitsubishi, and I will be using GXWorks 2 for 99% of them. I had the idea of writing the comments to a CSV file, Translate them there, and then just read them from CSV back into the project. I have tried numerous methods, but it seems the CSV loses format and isnt able to be read back into GXWorks. Some of these comment files have almost 10,000 comments. Do any of you have any suggestions on the best way to translate these comments over, in a more automated way than manually one-by-one.  Thanks in advance for any support you can provide!
  8. I'm using simple function block, one input and one output, like in this example: Problem I have is how to call function block and use inverted (NOT) value , ie instead 5.01 I need to use NOT (5.01) . Of course I could create new symbols that are inverted values of actual inputs but i'm trying to avoid that, number of addresses is significant.
  9. To calculate a walking or moving average I want to use WSFT and SUM in a function block. Does anybody have experience with this? The idea is to take a 1 hour average of a proces value and store this average value each hour. The software then have to calculate the walking or moving average over say 4 hours or 12 hours with a maxium of 24 hours. See attached files with logic but then not in a function block     Walking_AVG.cxp Walking_AVG.opt Walking_AVG.bak
  10. Hi, I have a problem because a TON Timer instance in an ST program does not start running. Is this a known limitation on FX5U CPU's or ST Language in General ? On the internet are some discussions, and there is a person which says it works for FX CPU's: But not for me.... And some discussions here in the forum: The last one is interesting, but it did not helped in this simple case.   For clarification, I created a very small program in GX Works3 (v1.057K) The FB instance in Picture 1 works very well if one sets M10 to True. The ST instance in Picture 2 does not start when setting M20 to True. Has anybody a clue? Any help welcome DWIM  
  11. I can debug my plc app with simulator. I created some function block, and inside functionblock I can inspect in and out parameters, as well as local variables. But in/out parameters values are not shown. Any solution? Im using Sysmac Studio 1.29.2 and selected a NX PLC in my project.
  12. Modbus fonction block error

    Hi everyone, first time posting here. I've got a problem with the Modbus MTCP-CP1L-Server fonction block. it worked fine for a good amount of time until i try to change an ethernet switch (not managed) on my network. at this moment the fonction block started to give me an error code (2211 ''unit is busy, can't execute''). So i put the old switch back again and I called Omron and they tell me to download Etherway and try to send some data to it but they can't do more. I did and BAM, it worked again. everything was fine for about a week and i was like, okay if etherway can ''solve my problem with the fonction block, i can put the new switch again, No I can't. It give me the same error, I try'd so many thing( put the old switch, everything that was possible in Etherway, change IP address, ethernet setting, reboot everything, connecting the unit direct to my PC. nothing can erase that error.  Unit is an CP1L-EM with built-in Ethernet port did someone had have the same problem, or have any idea that can help me ? thank. Sorry for my poor English, its not my first language.     
  13. Hello all, I am trying to write one FB for Analog Scaling in GX Works 3 Software for my Mitsubishi FX5U Plc... Unfortunately i am not aware very much about ST Language instructions of Mitsubishi Softwares. So the Code is Giving 5 Errors, i think the error are due to incorrect data conversion expressions, Can you please correct me with my code ? Here are the Variables RAW_MIN                   Word [Signed]                      VAR_INPUT RAW_MAX                  Word [Signed]                      VAR_INPUT SCAL_MIN                  FLOAT [Single Precision]    VAR_INPUT SCAL_MAX                FLOAT [Single Precision]    VAR_INPUT AI_RAW                      Word [Signed]                       VAR_INPUT SCALED_OP_REAL   FLOAT [Single Precision]    VAR_OUTPUT SCALED_OP_INT      Word [Signed]                       VAR_OUTPUT Here is the Code SCALED_OP_REAL:=(((SCAL_MAX-SCAL_MIN)*(INT2FLT(AI_RAW)-INT2FLT(RAW_MIN)))/(INT2FLT(RAW_MAX)-INT2FLT(RAW_MIN)))+SCAL_MIN; SCALED_OP_INT:= FLT2INT(SCALED_OP_REAL);
  14. Function Block addressing

    Hello all.  I have a program which has 8 function blocks. I recently added extra functionality to one of the programs (not the function blocks). I added the new variables to the global symbols table and added the new code, but when I compiled the new code, the variable addresses in three of the function blocks had changed. This is a problem, because we use memory cassettes to download new versions of code, so when the new version is downloaded to a machine in some far flung part of the world, these variables will be overwritten (they are hours run variable, so are important for servicing purposes).   My understanding is that CX assign's variable addresses in Function Blocks and we have no control over this. Bit if I only added variables to the Global symbol table, why are the FB addresses affected??   Any input appreciated. 
  15. Hello Everyone, I am looking for sample program which are compatible with Mitsubishi Gx Works 3. Program should contain some timers, counters, arithmetic, data conversation so i can see the instructions of each and every basic blocks... I am using iQ-F FX5U Plc with GXWorks3 Environment.

  18. Sample blocks for S7 1200 plc's

    Hi experts, please share the sample blocks for the EDITABLE TIMER block it should be editable from HMI(Siemens). And also motor run hour block. Actually i am having all blocks in tia v12 version and sadly i dont have the old software to convert it again. So please share the blocks that it shoud be work in TIA V14 for s7 1200 plc's. Please note that the blocks should use add instructions to calculate the time because i don't have much memory.

  20. Hi everyone, Using Cicode programming ... I'm try to make a function empressed Button's input command that still running forever until the user press the Button again .. so if i press the Button at first the function inside Button will be running , But i wonder to terminate that function by press same button second time or don't mind if you suppose other Button for stop running the function ... plz help to make a code or something else to stop running of my function.
  21. Pointer Device memory

    To those who don't know the GX Works2 compiler treats any function block referenced used in your code as a place to copy the entire set of code data into your program. Function block calls are not handled like pointers even though the should be. [You'll consume all your pointer space by thinking function blocks are great.]
  22. Hey, I recently started trying my hand at creating function blocks. At the moment I'm trying to create a PID function block, however I keep getting this error: "ERROR: Variable does not have enough size." No idea why it does this. Can anyone help?  
  23. Hello, Completely new to Mitsubishi PLCs and I need to use a date and time stamp for data collection purposes. We have a Siemens PLC as well and this has the data type "Date_And_Time" which is what I need to replicate. I have been attempting to write my own data type but am struggling with how to go about this as it is not straightforward and I cannot find anything about how the Siemens Date_And_Time is made up so I have nothing to go off. Does anyone have an example of a data type they have made that is the same? Or is there a data type which does this already in GX Works 2 that I just can't seem to find?  Please help!
  24. Internal function block variables

    I have a function block where the first internal variable is showing as address H1420 in the Global Symbol table. When I add another retained variable to the function block then save and compile the code, the variable address in the global symbol table shifts from H1420 to H1488.  I need to retain the address as I will be downloading code and I need to ensure the address if H1420 stays with that variable.    Can anyone help with this?
  25. GX Work2 Comments in Arrays

    I am very new to the Mitsubishi PLC world (I have a lot of experience with A/B and Omron though).  I am having an issue trying to assign comments to an array of Globally scoped bits - I am also using Structured Ladder - NOT simple ladder.  Is it possible to do this?  I have contacted there tech support group and they were of little help.  I don't care if I update the label comment or the device comment, I just want to assign a simple comment that can be displayed (i.e. I am using this for step sequences).   Any help would be greatly appreciated!
