  1. 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,
  2. 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.
  3. 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?
  4. 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)

  8. FX1N sprinkler system control.

    Hello!  I have an FX1N PLC that I want to use to operate a sprinkler system.  It should have two functions.  1. 1x30 minutes of operation every day.  2. 3x10 minutes of operation every day.   Thanks for the help.
  9. Using sysmac studio, i get 4bytes binary data Data[24], Data[25], Data[26], Data[27] like this, the problem is that the 4bytes data represent my float data what can i do with that 4bytes lol If u see below images you can understand my problem.... thank you all,
  10. 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? 
  11. Hello, I have a Sysmac project that contains two NJ controllers and an NA HMI. I am writing the current time to different variables upon completion of certain actions using the system variable _CurrentTime.  I noticed that one controller was logging the date as 1-1-1970, and went to sync the clock with my computer's clock via the Controller-> Controller Clock... menu.  Upon synchronizing and applying, the controller clock very briefly displays the correct time, and then reverts to 1-1-1970. I went to the second controller in the project, which simply had the wrong time zone setting, and attempted to change the time zone and apply. Whereas before it showed the correct time for the time zone setting, it now reverts constantly to 1-1-1970 as well. When I go online, I've also noticed the _CurrentTime variable is not incrementing; it is always 1970-01-01-00:00:00.00. The HMI displays the correct time, and I am considering creating a mapped tag that shares this time with the controllers, but was curious as to what could be causing me this issue. I am also aware that 1-1-1970 is the unix epoch. Any insight?
  12. 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.
  13. 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?
  14. 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?
  15. CPT instructions on a PLC-5/40

    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.
  16. Hi guys, I just starting to use Sysmac Studio. Its a bit confusing as I am currently used to CJ series PLC. Usually, we can use P_1sec, P_0_2s and so on to create a simple clock pulse timer function. However, I couldn't find the command or FB to do that in Sysmac Studio. Anybody could explain on how to do that in Sysmac? Thanks 
  17. 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.

  22. EA3 Micro Panel

    I want to display the current time of day on mt Micro HMI, EA3-T6CL. Is there a function for this? How can I get the TOD to display?
  23. So I have done quite a bit of googling and i even reached out to our integrator but i am having a nuisance fault of "Watchdog Fault" Caused by periodic task overlap. The task is scheduled to start again before it is finished. I added all of the Programs in this task MAX scan time and it only came out to 102 ms. the task is scheduled for every 100 ms. The watchdog is set at 500 ms. The task is currently running at 146-148 ms and i confirmed this using a TON instruction at the end of the task followed by a reset. What can i do to get this down?? What would be the best practice? Move programs into another task? Make the task continuous? What would happen if i did make it continuous? I tried setting the task to 150 ms and the controller DID NOT like that. I was barely able to get back on line with it to change it back to 100 ms. CPU usage is at 91% and this task accounts for around 50% of that. Thank you all in advance for your help.
  24. Tracking the master clock

    We are having issue on a machine running kinnetix 5500 drives where we randomly get clock Sync Faults.  This particular machine is set up as a slave looking to another PLC(L36-ERM) on a different station of the same machine as the time master.  There are about a dozen other PLC's(totally different machines) on the same network and most are set up as masters for their own systems and to my knowledge they have never had this issue. There are also dozens of other devices connected to this network, and then this network is part of the facility wide network.( I apologize if this is a little wordy) We are pretty sure that the slave is finding a more accurate clock on the network somewhere and syncing to it causing the servos to fault. We have tried making both the master, and the local clock of these 2 particular PLC's higher priority than the others to eliminate this with no success. What I am trying to do is track what clock this particular slave is looking at as its master when the clock sync fault has occurred.  is there away to do this through ladder logic?  it seems like we should be able to get this information and save it so we can figure out who the culprit is.
