Hi, in Visilogic \Examples\Version 900\Project examples\HMI you can find V120_Personal_password.vlp Also V570 password sample project present.

Something like that MB91 MB90 ---|P|-------(S)--- But in Visilogic online you must reset MB91 before new start of MB90, then reset MB91 coil must be in net 7.

Please specify which type of PLC your question is for - Unistream or Vision.

While upgrading the control system of the parts washer, I ran into a supply problem now called "chip shortage". In general, there was a remote control box with V570 panel and a control cabinet at a distance of 20 m, in which the EX D16A3-TO16 extension module is located. It uses all inputs and outputs for the machine's needs. The start of the automatic cycle had to be done with protected hermetic buttons on the remote control box near the panel (this requirement is dictated by the abrasive that is on the parts that are loaded into the parts washer, this abrasive on the gloves of the workers can quickly destroy the touch panel). However, the V570 requires a snap-in module to connect two buttons. And this particular module was not available... The solution was found and the system is already working. Now in more detail. Two panel com ports (RS232) are used as two discrete inputs. Below is the button connection diagram and a piece of ladder code that explains the idea. The machine is already in operation. P.S. I will have to wait for the snap-in for some time and then connect everything as originally planned.

Hi, you can find idea in this topic Ausman find ladderart solution in Visilogic ladder subroutine that can be imported to blank project. You can implement the same idea for your project in Unilogic

Hi, maybe you have the latest firmware in in Samba. Please use Visilogic 9.8.65 and download firmware from this version for test. Write back about the test results Some tips in topic

Moved ... Hi, please read short info https://www.unitronicsplc.com/programmable-controllers-products/ For more detailed information, please see the documentation on the PLCs of these two types. https://www.unitronicsplc.com/programmable-controllers-unistream-series/ https://www.unitronicsplc.com/support-technical-library/

Moved. Google translate... good morning to all and for the past few weeks I have approached the world of plc programming as mentioned in the various posts I would like to make a simple program with the ignition of a three-phase motor connected to a pump in front of a Riels geared liter counter with square wave pulse output npn as an inverter I connected a commander sk that I have already configured. my plc is: v700 has 4-port analogue outputs 15 digital outputs 4-port analog inputs 15 digital inputs initials as mentioned PLC + HMI V200-18-E4XB I have already configured the ports to connect to the plc and configured digital inputs port 9 to npn with common + 24vdc in the joke I would like to see start engine engine stop engine rpm speed liters per hour. who is interested in making me the mini program please contact me x to agree. thank you e-mail tumminellocalogero@gmail.com cel. 3279368492 I am attaching the little program I made waiting thanks

Hi, i recommend to read Basics from this file CAN_open_schneider.pdf

I think you can try to replace only the NCP565ST12 (RFP 56512 marking) chip. FPGA is programmable and contains the manufacturer's configuration code, and if there are problems with it, then unfortunately replacing it with another unprogrammed one will not give anything. I am impressed by your research of the hardware and the desire to determine the causes of PLC failure.

These may not be the cheapest options, but they will probably be delivered to you fairly quickly. RS485 isolated RS485 not isolated However, you can also buy the Ethernet communication module for Visilogic connection and use port1 (PLC com1) for RS485 connection. Ethernet communication module

I am familiar with the V700 PLC circuitry and I can say that there are no electrolytic capacitors in the circuit that age even without operation. During the whole period of using such PLCs, I observed two cases of V700 failure. One due to problems with the external power supply. Another was injured due to the accidental supply of high voltage to the + 24V circuit of the pressure sensor which was connected to the V700 PLC Snap-in I/O. I was able to successfully repair both PLCs. At the same time, I observed the failure of a completely new V1040 controller on the board which, as a result of improper storage in a damp room (in the off state), oxidized the conductors on the board. The only thing that comes to mind about your problem is external influences. I know what a closed air-conditioned control room is. In automatic mode, everything is fine. However, when a person goes there - he temporarily turns off all air conditioners and usually forgets to turn them on after maintenance. The result is overheating of the equipment, emergency stop or alarm - switching on the air conditioners and heat shock in the equipment.

The best data is empirical data V130 is another animal ....

Simpie Download - place project to battery backed RAM - no upload possible, battery discharge = project lost. Download and Burn - make DLU backup in flash memory - no upload possible, but project do not lost when battery discharged. Burn "Upload Project" - Visilogic Upload possible, SD card project upload possible, project do not lost when battery discharged. Now if you reinstall motherboard to new PLC - you can see in info mode is it upload possible. Maybe only DLU backup in flash memory pesent.

Hi, Please find Visilogic Example project in Data Table directory V120_Data_log_with_time_stamp.vlp

Best solution - found the same model PLC and reinstall motherboard from original PLC to "new" one. It is not possible to upload project if Burn "Upload Project" option is not selected when project downloaded to Unitronics Vision PLC.

If everything works and reading speed satisfies you - leave everything as it is. To reduce the number of consecutive read / write commands, you should try to read not each address separately, but a lot of sequentially placed data by one command. In your screen you can see consecutive registers from one device 9-11, 20-28, 14-16. If you look closely at each device, it is possible to read all the data from it with one command and only in the PLC to extract the necessary data from the received packet.

moved. translate via google Good afternoon, the PLC of a team has the vision 120-22-UN2 and I want to connect to the PLC but it sends error 206, which software version corresponds to it according to the photo, The plc uses the two serial ports to connect to two delta drivers, i already stopped the program from the info screen but i still can't connect to plc

Hi, to solve your problem, you must specify which set of inputs / outputs, ie expansion modules or snap module is present. It is impossible to solve your problem by using only the V700 controller without additional expansion (or SNAP-ON) units. Since you have an NPN logic pulse signal that must be applied to the logic input and this input should preferably be HSC compatible input.

Good job. However, as always, I ask the author of the topic to briefly tell us about the journey. That is, which version of the firmware did not work and which solved the problem. This is important for future forum participants who will follow this path.
