  1. I do not test it but maybe solution - use legal entry bit and after correct entry - activate screen refresh via legal entry bit positive transition (Utils/HMI/Refresh HMI Display).
  2. Yes Ausman, i do the same thing... but in this case visilogic stop to open his own "normal" project... And after try to recovering with "OK" button - Visilogic crashed. Only reinstall help to solve this issue.
  3. Hi, is it possible that second compared value goes from ADC or another not filtered sorce? On display you maybe have visualy correct but flashing with high speed result. Output maybe is not high speed and cannot activate with the program scan speed.
  4. I went through the problem of updating not only in the computer. You can't even talk about a smartphone at all - it lives its own personal life ... The printer did not want to print because the memory defragmentation requires an update. Now you should probably expect updates for the microwave, vacuum cleaner and electric kettle. P.S. Therefore, from time to time I make a full copy of the contents of the computer - with a note - everything installed worked ... But it did not help: I open visilogic projects 9.8.65 from a second system running from another hard drive with the latest v
  5. Hi. Maybe my experience will be useful to you. I created a control display for the extruder. Using standard graphics, I drew the desired interface and added controls. However, when I started loading it all into the V1040 it took quite a while. Accordingly, the speed of the interface was very low - while the panel redrawn all the graphics elements when changing windows - the user saw how it does it. Then I did the following: 1) deleted all controls (copied to another window); 2) exported the HMI display (drawn graphics) as a BMP file to HDD (use standard Visilogic Export Disp
  6. Hi, maybe best solution is to use Ethernet card and connection to the Samba. Device like this https://minovatech.de/mcr08-nfc-rfid-hf-en.php has Ethernet, RS232 and 485 port present also.
  7. Hi, is it jumper settings in correct position? Input default is Digital!
  8. Maybe you must try to use Joe Tauser PTO Example for test I think the problem is in activating the stop function in homing via sensor. You system see sensor and decelerate. After that you must to give the command to return to 0 and only then go where you need to go.
  9. You need to post more information about hardware configuration. You must use this manual for configuration https://unitronicsplc.com/wp-content/uploads/2019/08/SPEC_UAG-XK_XKP_-XKPLxxxx_UAG-CX-XKPxxx.pdf Maybe some part of your hardware combination is not recommended, please see this table in above From this manual: When daisy chaining, you can include only 1 Long -range adapter. You may connect it directly to the controller or to any of the elements that are expanded from it.
  10. My electrical engineering teacher said: 1) Do not believe your eyes - take a measuring device and measure. 2) Only the wire connected to the tested ground has no dangerous voltage. 3) The device will always protect the fuse to which it is connected. The list goes on, but the first point is probably related to this topic.
  11. I came across a power supply which, with a slight overload, switched to current limiting mode and reduced the voltage accordingly. This led to unstable operation of all consumers with microcontrollers on board. It is also possible pulsation that constantly restarts the unit. However, I cannot predict what caused this case.
  12. Please check process via Ctrl Alt Del - sometimes visilogic present in process or application but not present on screen. It is not possible to start another one while "hidden" copy is active. For run different versions you must use Version Swapper. It is not possible to run another version if present is registered. Best way - uninstall all version, clean registry and install all needed via Version swapper. I use Visi on XP SP2 and Win 7 on notebook, and XP SP3, Win 7, W10 on PC starterd from different hard drive. Only one problem found - when try to
  13. Hi, 1)Please check HW-config in Visilogic 2) From manual ---- Connecting RG Pins. For correct operation of digital and analog inputs and for EMIimmunity, connect the RG pin of all the expansion modules containing RG signals to the adapter module 0V signal. The overall length of the wire connecting the RG pins to the adapter 0V signal must be less than 3 meters. Connect the RG pins inseries (daisy chain). To facilitate this, use both the RG pins. 3) From manual----Do not connect the neutral or line signal of the 110/220VAC to the device’s 0V pin. 4) Use another power supply.
  14. As far as I understand the author of the topic - he was going to create a system that collects data on the operating time of the plungers. He does not need to control them - but only count the time of the on state. To do this, he was going to connect the output signals of the existing in the system controller to the inputs of the samba PLC. If so, then his actions are clear and correct. Accordingly, Ausman emphasizes that if the Samba PLC controls the process - then the connection of its own inputs to its own outputs is redundant and can be replaced by a simple program reading of the
  15. Thanks, This is foto of installation for elevator - NEMA 4 cabinet with two VFD inside working now on 3 production lines. The first of them was installed 2 years ago. The customer had problems with the wires. Shielded remote control wires and cables to two motors are damaged very quickly (galvanic chemical production). And this often led to the failure of VFDs that were mounted in a large control cabinet at the beginning of the line. We changed the scheme - put two VFD in the NEMA 4 cabinet and installed it directly on the elevator. Currently, only a flexible mobile uns
  16. It is little copy paste mistake in table 0007 is not 1.5kW drive (row#6). I use the rule 1 to 8, respectively, 1 volume of the frequency converter should correspond to 8 volumes of air in the box where the VFD is placed in a closed cabinet. It works on an elevator that moves over chemical baths. However, there the ratio of operating time to the total time of the VFD cycle there does not exceed 40%. P.S. I cannot upload picture of this installation (my profile attachment limit if full)
  17. Hi YINGD! You must use data from this table from unitronics support https://support.unitronics.com/index.php?/selfhelp/view-article/umi-unitronics-vfd-heat-dissipation and make some investigation with this document https://literature.rockwellautomation.com/idc/groups/literature/documents/td/sp200-td001_-en-e.pdf Then you can see - is it possible to use UMI-0015BU-B1 in NEMA 4 Enclosure with predefined box dimention.
  18. Similar question in topic and some tips...
  19. Hi Ausman, in this case i found many different solution on real machines. As for me no earth contact on power supply is MW idea for cost saving. Now i see both variant of MW PS - old MDR with EARTH and new without. Old wariant is approx 10-15% bigger price. But I think the grounding (or not present gronding) of the primary side doesn't matter if the power supply has a grounded minus of the secondary part. Maybe you can find useful this link. https://www.klocknermoeller.com/klockner.moeller/Wiring_Manual_English.pdf start from p.1-17. In this
  20. Hi Skof, Stepper motor by definition - an open loop control system. After switching it on, it must be set to a known position. (Homing process) You probably think it will be able to stay where it left off. However, this is only possible if the driver controls it by natural characteristics (magnetic step). That is, the 200-step/rotation motor must be electrically rotated only for 200 steps/rotation. If you use a driver with step divider(from 2 to 128 or more) - after shutting it down, it will forget electrically divided step where it was (and motor will rotate a little by hims
  21. Maybe my post will not help solve the problem with stepper motor, but I want to note (you wrote about the possibility of breaking the valve) - this system, even with the best settings, will break it someday ... Therefore, I recommend abandoning the stepper motor and consider other options: 1) use the 3 state control actuator with analog feedback (Belimo or other type), and apply the control algorithm idea described in the example V120_PID_motorized_valve_output_with_physical_feedback.vlp from Visilogic help. 2) use the 3 state drive without feedback but with

    I thought that there were not enough months on earth. In fact, if you look at a welding machine from a well-known manufacturer, you can guess why it stopped working. The time machine told her to make this leap, cancel the license and stop work. However, the license was indefinite and therefore on the second attempt it changed the number of months in the year .. I had to overcome this shift in time - the welding machine works. However, evidence of the time machine remained on photo. 😎
  23. Please share model or nameplate photo. Is it problem present from start with V350 or it appears on long time normal working installation?
  24. Use different power supply possible only when output is "isolated". Fof example V200-18-E3XB has 2 isolated pnp/npn (source/sink) transistor outputs and 4 isolated analog outputs. However, the user must remember that these separate power supplies must be turned on and off at the same time or in the correct sequence. As an option - start powering the panel and then power the output - and turn it off in reverse order. The PLC uses output drivers that are protected against short circuits, overheating and usually undervoltage. Turning off the driver power (in your case + V0) could t
  25. Hi, I will try to describe why it works without a connection. 1) There is output board inIside of the Unitronics OPLC controller. 2) Each of the solid state outputs is a part (one channel) of the few chip VN340SP (or something like that on foto). 3) To send signals from the processor to this chip, we must have one common wire and several separate ones for the required number of outputs. This common wire also neded for power the VN340SP. This wire is the OV contact you specified. 4) This OV contact is connected to the main power OV contact of the PLC panel through a small
