  1. Capture Date and Time

    I would like to capture current date and time to registers in the PLC. I would prefer to use a function block, if possible, since I need to do the capture at different places in the program. I am using a CJ2M. How can I do it?
  2. Convert time

    Hello. this is my firs post is possible to convert the elapsed time of timer to real or int i need to make some math operation with the elapsed time thanks  
  3. There have been many good discussions on the applicability of cloud-based solutions for manufacturing and process control systems. On one side, some people have concerns regarding security and control of the information, on the other side, there are identified benefits enabled by cloud systems. From VMS minicomputers to DOS and Windows, from ArcNet to Ethernet, it is inevitable the industrial automation systems shall adopt the technologies that are getting predominant in IT general use; the current environment that I am calling the “Cloud-iPad era” is no different; therefore the practical discussion is not if those new technologies will be applied in the industrial environment, but how. This paper is not intended to join the conceptual discussion about the cloud, but just to present a few simple practical examples, where cloud technologies are already enhancing industrial automation solutions and enabling new business opportunities.

  4. Time Input from NB Screen CP1L-E

    Hi guys,     I am trying to make a controller for an oven using MODBUS with a CP1L and an NB screen. My oven program will have 10 stages in one baking cycle, and the parameters for each stage can be modified individually (temperature, blower speed and time). I have set my number input in the NB screen to be a unsigned int of 2 integers and 2 decimals, and it writes to H4 in plc H memory. I move this value from H4 to W4 in the PLC, and input W4 into a timer (T0000). I have tried data manipulation and still have no success in getting this to work properly. My CP1L timer is set to BCD mode, as I am using premade MODBUS function blocks which are programmed with timers in BCD mode. Does anyone have any pointers regarding this? In the screenshot provided, the number i inputed in the HMI was 60.00.
  5. 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!
  6. Hello - I am currently setting up a program to control a downlane conveyor motor and ran into the issue of operators leaving the conveyor on through their breaks/at the end of the shift.... I know, shocking . Anyways, the essentials of the program are the following - ladder logic, start/stop PB station, a sensor that says when I've seen a box for x-amount of time I will turn off, when the eye is clear for x-amount of time I will turn back on. When trying to 'solve the problem' of the operators leaving them on, I figured this would give me a chance to use a RTC (real time counter) and program it so that at various times of the day I will send a single shot to verify the relay is CT is open. I've enabled the RTC on the Micro810, dropped a TOW but do not really understand how to set the TOW block up. Hopefully that all makes sense. Thanks,  grubb
  7. OK,  I have a program in a Control Logix 5561 controller(ver. 19.52) that every time we go online with it, the communication between the PLC and the PC running RS5000 is so slow you cannot navigate the program efficiently. I am new to this facility but I noticed the programmer used 20 different periodic tasks to organize their program, mostly running at 30ms intervals. several are set to 10ms and some are even set to 3ms. I have gone through and found out that the short interval tasks have been overlapped 10's of millions of times, and the combined total of all scan times is over 160ms. I have a strong feeling this could be causing our comms bog down and possibly other erratic behavior but would like a second opinion. This machine has 2 indexing dials, with work stations that do work between indexes, Pick and Place operations, etc.  Is there even a need to be running these with periodic tasks? All thoughts are appreciated. Thank you
  8. Hello, I am having an issue with FIX Dynamics Real Time Database and the database columns available within when trying to query the database. On a system running iFIX 5.0, there are 19 data columns available, LHS of attached screenshot (in the screenshot example, crystal reports is used to view the columns). However in iFIX 5.9, only 15 columns are available (RHS of attached screenshot ), how can these missing columns be made available to be accessed? Regards, John

  13. Tia Portal V14 Real time graph

    I current have 2 variable: Displacement vs Pressure. I need to draw a real time graph on Comfort Panel. The problem with using just f(x) trend is that the minimum time between updating a point is 0.5 sec and that is for ever in my application as the whole cycle last only 5 sec and I have to plot 500 points in that time. Is there a way to do real time graph using Historical data without any time delay. If anybody can guide me through any sample program or material would e helpful. Thanks
  14. Hi All, On our plant, we are using one Rockwell  PLC model 5573 with HMI(Allen Bradley 1500P). I am automation engineer but I did not work on the Rockwell PLC. Now I am planning to install the GPS clock on our plant. And I want clock will synchronize our Rockwell plc as well. Could someone advice what is the best option for this model to do the time synchronization.   Thanks in Advance, Warm Regards/Waqar
  15. Hi.  I am quite new to Sysmac Studio. Working on my first project with it now, coming from CX-series.  I have got one problem i can not find a solution to. On the NA-HMI I want to have an input display where i can input a time of the day.  As far as I can see NA do not allow me to use "TIME_OF_DAY" variables in the Data Edit component. Is there a solution to this? 
  16. Cycle Timer

    Hi all, I try to realize a cycle timer. A counter is triggered by a movement ( clamp close ) Then the machine does it things, piston here, and there and when the clamp closes again it should show me the real cycle time. Is there a timer/counter that is independent from the PLC cycle? I am using a CJ1M CPU11 Ver. 3.0
  17. I would like to use the actual Cycle Time (in seconds) of the NJ101 CPU in a Structured Text  math equation.  You might also call it the Task Period... However it's called, It needs to be the amount of time that has elapsed from the last calculation of the ST math equation.  It must be a variable that also satisfies this looping equation: Time:= Time +cycle time .. so that the master equation, which is calculating position information, based on TIME .. is up to date with each calculation in the loop. How do I insert that cycle-time, which might not be identical for each loop, (or, is it) ?  Thanks, Regards, Michael  
  18. In my application the LMC automation controller will be calculating date-based lot codes. I would like to synchronise the internal clock with a time server such as pool.ntp.org. I can't find any info in the Schneider-Electric SoMachine help files or on the web. Does anyone know if this is possible?
  19. Hi,  i want to read real time and date in simulation mode. How can i do this in Unity pro? Thanks for helping
  20. Time Based Interrupt

    Hello guys!!! My system constist of: CPU: Q03UDE Some I/O modules Some Intelligent Modules (Q68ADI,QJ71PB92V...) A High Speed Digital Input card QX80H (setting responce time 0.1msec) 1 digital input from QX80H occupied to count the pulse that a flow meter sends. The pulse corresponds to the totalizer of the Flow meter (FCI ST100 series Thermal Mass) and it has fixed width 0.5msec. The flow meter sends 4 pulses / minutes approximately according to current flow rate. My Main Program has scan time 2.4msec. I think that PLC ignores some pulses because of the pulse width is lower than scan time of my program. Is it right? So, the PlC program calculates wrong total flow.... What can I do to avoid this issue? Attached you can find a sketch what I mean... I though to program a time based interrupt every 0.3msec. Is it right and possible in Q03UDE CPU.....? If yes, how can to do it? Thanks a lot in advance for your any help!!!
  21. Hi everyone, I would like to create a PLC code using RSlogix 5000 program in order to measure time delays on the network. Can anyone help me to do this? Thanks.
  22. Hi! I just started with PLC programming. I am trying to get the time between a output signal and a input signal. The problem is that the time is ~200 ms but when i measure it with this code:   TONR(Timer1); IF PosFeedback <= PosFeedback_Min & not Timer1.Reset THEN Timer1.TimerEnable := 0; FullCloseDeltaTime[1] := Timer1.ACC; Timer1.Reset := 1; END_IF; IF (move & not Move_LastScan) THEN //Start timer Timer1.TimerEnable := 1; Timer1.Reset := 0; END_IF; Move_LastScan := move; i only get even values in intervalls of 50 ms like 150, 200 and 250 ms. I have changed the real time sample rate to 11 ms so i don't understand why i don't get a more exact result. And i can see in my trend that the time isn't exactly 150, 200 or 250 each time. I i tried and time my own click on a button and i see the problem is the timer, i only get values in an interval of 50 ms. Is there a way to make the timer more exact?
  23. Hi all,  Can someone please help me, I am using a Micro830 Controller running connected components workbench software to program the controller. I want the use the Real Time Clock of the controller to control an output to turn on everyday at 01:30am and turn of when it receives a signal from an input. The output will control a backwash valve that will operate and activate a cam switch internally that sends a signal back to the Controller to say the valve has operated and can now stop sending the signal to the valve. (if that makes sense). I have tried playing around with the RTC instructions but I cannot seem to get it to operate how I want it to. Any help would be much appreciated. EnvrioService
  24. Hello all, I was asked to check if there is a PID real - time software which automatically calculates PID loops parameters and update the PLC registers or HMI ( by OPC server etc.) when the process is working and "breathing". REAL-TIME. Not PID simulator or PID tuner based on measured data, but a software that will calculate and update the PID parameters in real time while maintaning several PID loops simultaneously. Are there any suggestions? Thank you, Olesia
  25.   Dear, I need some help with an application in ml1500 with the RTC . I need an exit is enabled by days of the week . I´m programming in Rslogix500. Program follows the image. If possible help me. Thanks Daniel.
