  1. Hello. I'm using OMRON NB Display Did someone already made time adjustment from NB to OMRON PLC? What I'm trying to do is to adjust time  from HMI to PLC. Since now I have done time sync from PLC to HMI using timer and data transfer. Now I would like to adjust current time in PLC using NB HMI. I know how to do it, but I'm some kind a lazy person. In our country there is a saying: " Don't reinvent things that already exists" Thanks.   BR, Andrej.
  2. I would like to get some feedback or alternate suggestions in terms of monitoring a database connection. The attachment here shows the current programming for the DB_Connect function block which requires the Execute input to constantly be ON.  From what I can tell, if the connection is dropped - let's just say the Ethernet cable is unplugged - this input will still be on, and according to the function block, still connected. The Get1minClk is in place to continuously try establish this connection once powered on, but I cannot find any way to periodically check this connection without dropping it and reestablishing it.  My understanding is the _DBC_Status.Run only checks that the PLC service is running properly, but is there a way to monitor a heartbeat of the connection TO the database?  The only way I've found thus far is to drop the connection and reconnect.  But this would be detrimental to the system as it would possibly be reconnecting to the database while trying to write to out to it and hold up the show.  As it stands in the second image, the Ethernet cable is unplugged, but the connection shows no errors. Thanks and happy Friday! -K  
  3. Real world simulator

    When we simulate a plc program we have to manually input the changes in input(like magnetic reed switch) For example when a cylinder goes from up to down reed turn OFF and reed down turns ON Is there any program available where we can define such things that will turn on and off during the process automatically.
  4. Hey guys,   I am looking to query a database through FactoryTalk SE.  I will be scanning packages, and using that bar code to find a lane assignment from the database.     My question has to do with where the VB script will reside in the FactoryTalke SE program.  I want this script to run at all times.  I see that each screen has a "VBA Code" but I am assuming that these will only run when the screen is visible.   Where does this have to be stored in order to run all the time?   Thanks In Advance!
  5. I am not sure if anyone know any websites or sources ,to practice and program same as real projects. I have seen many websites but they are not realistic.
  6. Hi friends, The scene is like this... I have some 200 energy meters whose readings are continuously logged at 15-min intervals into a logging table. The meter does not have any other value logged. Let's consider these readings as analog tags. However these tag values are continuously increasing to ever larger numbers. Thus we have a problem for display on trends. Customer now requires that the Citect shows usage trends for any meter for a specified period of the past. That is to say, the meter that he wishes to observe is selected - along with a period typically between 2 dates (perhaps also with a sampling period) - and the trend must appear. So in other words, given a single trend object, how do you make values appear for any selected tag on this trend. Perhaps this can be overcome by some genie/super-genie mechanism. My approach to this is...For the selected meter, I use SQL to query the 15 minute logged values (also taking into account the required sampling period) taking the reading on starting date as initial. All values thereafter are subtracted -within the SQL query- and the result of this query is kept in a 2 dimensional array(x for time, Y for value) or a new database table so that the trend displays values starting with zero. This much I can do with Cicode. After this, I need a method to display the values so obtained in a trend object. Essentially this is the same as feeding a trend object with a set of X & Y values that I have in the form of an array or in a database table. I shall greatly appreciate any help to meet the above objective. Thanks for looking in. With best wishes.
  7. Hey guys,   I know this is a topic that has been discussed before, but I am having trouble finding exactly what I am looking for.. I want to know the most efficient way to record data from my PLC to an Excel file on my PC. I want this to be done without the use of the PLC's webserver.  Specifically I am trying to record vfd speed every 10seconds with a time and date stamp. How can I do this?   Thanks, James  
  8. Hi All, I just take over a project which involve accurate positioning and movement up to 0.010mm(around 10 microns) of a servo motor. I found out that my motor always move to an incorrect position. Let's say I want it to move to absolute position of 5.210mm, I found out that it may move more till 5.235 or move less 5.190(something like that). So i start to check if I'm outputting correct pulse. Using CX-Drive, I connect to the driver then i found out that the pulse is correct and consistent(for example i use my pulse per revolution and pitch to determine how many pulses) Currently I'm using an incremental encoder and servo motor and my PLC cycle time is around 12 ms and my servo move at a speed of 0.66mm/s. So I was wondering if my PLC scan time will affect my accuracy in moving ?? I'm using a CJ2M PLC with CJ1W-NC413 pulse card , incremental encoder and a servo motor. I want to make sure is not software limitation or anything wrong on software side before I bring it to my mechanical team   Appreciate all inputs here and thanks!
  9. Good Afternoon, I am wanting to do two things with and ORMON PLC and HMI with CX-Programmer and NB-Designer. 1. I want to display the current time from PLC on HMI with the real time clock. 2. I want to be able to enter a time on the HMI which will be compared to the PLC time and will stop a process when when the entered time is equal to the actual PLC time.  If I can have some help with this that would be a great help. Thanks,
  10. Now I working on omron CP1H PLC, i'm receiving ASCII number from another PLC which is something like this  "#3031 #3030 #3030 #3030" which mean 01000000. How to convert the ascii number to real number or bcd without separate them? I know how to convert them which is using HEX but its turn out the number will separate into this 0100  and 0000.
  11. Hi, I am trying to convert a variable of REAL data type to DWORD. I 've tried using Real_To_Dword function which works fine if the real number is integer but when the real is decimal the function rounds the decimal number to INT first (I ve also read it in the instruction manual so no surprise here). I 've also tried experimenting with the function CopyRealToDWORD but again the outcome was not what I expected. Is there another way to convert decimal real numbers to DWORD without losing the decimal portion?
  12. Hi, guys.I am struggling to develop a solution for a costumer in a Historical Alarm Viewer screen, I am new to Cimplicity and to database supervisory interface. Among other things, the customer is asking to:- Change the "A"; "R"; "G"; "N" notations under "log_action" column to somenthing more intuitive for the users (operation). Please have a look at the image "image.jpg";-Change the point manager process "MASTER_PTMR0_RP" log under "logged_by" column to the user that is currently logged in. Specificaly saying, when I send a command (changing a setpoint or issue a reset command, for example), although it is the user acting, the historical alarm viewer logs the action as "MASTER_PTMR_RP". I Imagine that is because this process is reponsable for exchange point data to/from the IHM points database, but it is still essential to the system administrator to know which user sent that reset command or changed the variable setpoint.The log inputs at the image "image.jpg" has boolean and integer commands (".CXX" sufix);-Log into the historical alarm viewer if the user logs out and what user logged in.It is valid to mention that I am using the ALARM_LOG table (apparently it is the only table working with the application, DATA_LOG, EM_LOG and the others simply do not work, they don't show any column at all, honestly I don't know why).I tried to use Microsoft SQL Server Management Studio to edit the table information, but, somehow, it seems to be blocked to edition.I imagine they are some specific configurations, but I have no idea on how to acomplish them. Maybe if I could use other tables would fulfill the requirements, but , like I said, they are not working (right now I am trying to re-configure the Database Logger from the beggingin to see if it works with other tables).If you could give me some inisights on how to change these settings I would be very grateful. I will be happy to give more information if needed.Thanks in advance.
  13. So I have a plc program where most of the outputs are based on a counter that goes from 0 to 1000. The counter speed is adjustable and is generally set to run through a full cycle (count from 0 to 1000) anywhere between 0.5 to 2 seconds. The problem is, when I try to energize an output by using an EQU instruction, it will almost always skip the count because the scan time is not fast enough. I've been using a LIM instruction which has been working, but its not quite as accurate as it needs to be. I switched the counter logic to be continuous to try to make it faster which made it almost perfectly accurate... But only in the continuous task; it made the other periodic task significantly less accurate. I was curious if any of you had any tips on how to remedy this or just general help. I am still relatively new to PLCs and ladder logic so any advice would be awesome, Thanks in advance! Edit: The purpose of the counter is to cycle through from 0 to 1000 over and over again. My outputs actuate during a certain interval within this cycle (For example I would say actuate from 300 to 800 and it would stop and end once it hit those values via an EQU or LIM instruction). I wrote the logic as follows: First I calculate how many cycles per minute I want to perform, using that value I calculate how many times I want to increment my counter per millisecond. Then a timer is given a preset of the total cycle time. While that timer is running I continuously multiply the timer's accumulated value by the "cycle count per millisecond" that I calculated earlier; the resulting value is the current count that all my outputs are based on... Hopefully that makes sense, I know it's not the best but I could not figure out a better way of doing it and I know rounding is certainly making the accuracy worse. My hardware is: Allen Bradely PLC (5069 l306erms2), 5069-ob16, 5069-ib16, and a Kinetix 5500s2 Driver for my motor(s)

  18. I have a function that reads ASCII code from a transducer, converts the code into characters and places the characters from the serial buffer into a string. Now, I am trying to convert the value in the string into a 64-bit float number. Any ideas on how to do that on the CCW? 
  19. Structure Text REAL constant

    Hello. I'm having difficulties of how to write REAL constant in ST. For example (Gap1 is defined as REAL): Gap1:= UDINT_TO_REAL(P_Cycle_Time_Value) / +1000.0;     RETURNS ERROR ERROR:   Conversion cannot convert from Integer Literal to REAL I have also tried 1000.0 If I use:  Gap1:= UDINT_TO_REAL(P_Cycle_Time_Value) / INT_TO_REAL(1000);  COMPILES OK My question.. How do I write REAL constant in Structure text? I don't want to use  INT_TO_REAL anytime I want to do calculations with constants.. Thanks. BR.
  20. The only thing I can find in help re using the buzzer is to use a multi function button. I want to use the buzzer as an alarm buzzer and turn on $SB13 or $SB14 from a bit in the PLC. Can anyone help please?
  21. Real to 3 decimal points

    I'm fairly new to Mitsubishi and I am trying to limit the amount of decimal places of a real value down to 3. I am using a FX3U CPU and the only thing I see in the manual is that real values are stored with approximately 7 significant figures. Is there a way to limit the amount of figures after the decimal point to 3 without converting to an int value? Also does restricting the decimal to 3 points on GT works change to PLC value at all?
  22. I'm working to fix/improve the functioning of a program running on an a PLC5/40E.  I think high Scan Times are a big problem with this current program.  ((Backstory:  someone added some quasi motion control, and it sort of worked for a while.  Now that it's broken, the operators of this machine want it back. ))  I'll keep my question simple, PLC5's are new to me: There are 36 rungs with CPT instructions as the sole output, a third of these instruction are executed every scan.  I'm going to replace them with MOV instructions. My question is, is there any sneaky PLC5 reason to do a CPT instead of a MOV?  Is there a better way to do this? The CPT instructions that execute move integer values to a data file used by the HMI to control the coloration of touchscreen buttons.   Thank you for your time. PS: I'm new-ish to this forum, please feel free to let me know if my question was asked correctly or not.
  23. The CC-Link system on a machine has been intermittently dropping out.  Normally the Link Scan Time runs at a solid 87ms.  When the system "drops out", the link scan time will increase.  Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle. There are 33 stations on the network.  The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.) We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane.  Is it possible for one station or one of the cables to create a network wide problem?  Any ideas thrown at us would be appreciated.
