[NTP amd DST]

Hi,

I did check for number of Project Examples back, and all of them use port 123.

Where did you found port number 555???

DanT,

Do you have EDS file for module?

Import it and if there are no errors - required structures will be created.

 

[New computer - VisiLogic won't install]

I am not sure where visilogic stores the temporary install files, but I would try to find that, and delete what's there.  Also look in HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\ and see if there are any remains left there that you can get rid of. 

Hi all,

I will tell my short story about registry editing:

I did Registry edit at big Network Management System (not for the first time), but this time I failed into big problem - Microsoft Server being just "bricked".

- The bad - "bricked" Server.

- The good - I remember at what hive I did edit, and there were number of similar Network Management Systems at lab.

So I did copy of the same hive from one of working Network Management Systems to this one, used one of available at Internet tools to boot computer from CD and import hive I killed.

Required number of reboots to fix some things - and my salary bonus stay with me.

Lets suppose what happens if only one computer exists with this configuration.

 

So Registry editing is so simple...

And you should decide if you do it or not.

Happy Registry editing!

 

[V1210 - EXF-RC15 WIRING]

There is 4A fuse inside.

So if your power supply has load capacity less than 4A, than short time reverse polarity may activate power supply short circuit protection.

It is recommended to be careful with power supply polarity.

Bstip,

1. What model of USB-to-Serial converter do you use?

Do you have other model of USB-to-Serial converter?

or example FTDI based chip. Try it.

2. About commu8nication speed - recommended to keep it 115200 (default).

It is recommended to use PLC COM 1 serial port and check that it is configured as RS232 115200, 8, N, 1.

*Start PLC when pressing I button to start in STOP mode with default RS232 settings 115200, 8, N, 1.

If PLC has touch disp[lay - power PLC when touching display.

When down counter appears, release and then double-touch display to start in STOP mode with default RS232 settings 115200, 8, N, 1.

Repeat download.

3. Use "Stop-Download-Reset" mode to download project.

[U90Ladder - run without admin rights ?]

Hello all,

When you asking for help, please always state U90Ladder/VisiLogic/UniLogic etc. version.

Do not write "last version".

Knowing exact version will make our help fastest.

Anyway, first installation should be processed with Administrator rights (assist your IT), then replace file.

Replacement will require Administrator rights as well.

Then you will continue your work without Administrator rights.

Knowing your version we will send you link to download proper file.

You have to set Timeout to 10 sec.

Then check again.

[Visilogic & Unilogic Mapped Drives Fix (Worth Pinning)]

We do not recommend to work with projects, located at mapped drives, or flash drives of any type.

We recommend to copy project to local drive, work with it, than save changed/edited copy back to your archive with a new version number.

In case of USB interface problem, or network problem, you can finish with lost projects.

[Schneider PLC Counter+Timer]

Jpalas,

This forum is for Unitronics PLCs.

If you are working with Schneider PLC only - we cannot help.

If you should interface from Schneider PLC to Unitronics PLC, then better explain what you should do on Unitronics PLC and what communication protocol you use to communicate between Schneider PLC and Unitronics PLC, and what Unitronics PLC model supposed to use.

[Strange problem with same project in different Unistreams]

[Reverse Engineering the Algorithm]

Tested and approved:

When battery is discharged to some predefined level, than engine does not stop at red traffic light.

Even if battery is charged - very slow motion prevent engine stop.

For me engine stop is very annoying, especially at short traffic light, when my car is not first, and other cars has similar behavior.

So it will take 2-3 times more to pass junction with a short traffic light.

It is possible to use Action from Ladder -> "Take Screenshot":

The image is saved, with a time stamp, on the controller's SD card in :\\Media\PrintScreens.

[SM35-J-RA22 analog input showing 32767 after wrong wiring]

SM35-J-RA22 has 37 ohm resistor at current input.

Applying 24V dissipate ~16W at small resistor.

Looks like there are 2 groups of peoples:

1. Read and then do.

2. Do, then read, than say "wow/heh...".

 

[Is there a max length that will work for serial communication?]

You can find all information at Internet (Google or other search engine).

It is recommended to use RS485 interface instead of RS232 interface.

[Visilogic simulator developed third party company]

Do not count on this simulator.

Better work with a real PLC.

 

[I think I found a bug in the visilogic software?]

1. After loading timer value to ML, divide ML by 100 and it will be in seconds.

2. The fact that linearization accepting big values (ML or MI) does not mean that you should use big values.

There are multiplication and division inside linearization FB and in some cases result may surprise you.

2.1. You always should test worst case.

2.2. In case of not accepted results you have to optimize used numbers.

B.R.

 

[I think I found a bug in the visilogic software?]

This problem is "invented".

Vision timer has format:

HH:MM:SS.mm -> 5:00:00.00

Not X1=1800000 (timer value 5:00:00:00 loaded on ML)

Minimum timer interval for timer is 10 mSec.

For 5 hours interval you do not need precision of 10 mSec.

So value in ML for 5 hours (in seconds) should be 18000.

Hope that precision of 1 sec will be more than enough for your linearization.

Even 1 minute step will be good.

In this case linearization should work.

If not - use formula from Help.
