If your project will require a lot of continuous changes, I advise using the option to add a color on the rungs, that way you can easily spot changes between revisions. 

I don't always start using the latest version of VisiLogic right away. Has this been added, or are you thinking of UniLogic?

[Formula not working]

When I program that function I get 1.65126 for MF 1 using 819 stored in MI 6.

Do a search on MF 1 , MI 6, & MI 610 to confirm none of those values are being overwritten anywhere else in the program.

Also, if those ladder rungs are in a subroutine, make sure that subroutine is being called in the Main Routine.

[V130 and EX90 physical connections, and dumping a project.]

You have a large task ahead of you. I only have time to give you a few pointers and likely someone else with chime in with more.

- There is a lot of information you can use on the Unitronics website. Download the spec sheets for your V130 PLC and the EX90 I/O module. Your V130 has built-in I/O which includes 20 digital inputs, 2 analog inputs, & 16 transistor outputs. Expansion I/Os can also be added. I don't have any experience with the EX90 expansion I/O module, but I thought this module could only be used with a different PLC (M90), but perhaps I'm wrong. The EX90 has 8 digital inputs and 8 relay outputs.

- There are two ports that come standard on the V130 - the EXP port which is only used for adding expansion I/O modules, and a serial port which can be used for communication purposes, including downloading the program from VisiLogic. One additional port can be added. My recollection with this PLC model is that by default you cannot upload a program from the PLC to VisiLogic unless the original programmer specifically enabled that option (most do not). If you don't have a copy of the VisiLogic (.vlp) file, you may be out of luck on any program modifications. If you don't have that file you need to be directing as much time and effort as you can to locating it.

- Unless you have a computer with a native serial port, be sure to purchase a USB-to-serial converter that uses the Prolific chip. The one I use is the Trendnet TU-S9, but there are others.

- Your VisiLogic installation came with a number of example programs. Review them to see how VisiLogic works. The ladder logic is essentially identical between all the various PLC models.

- Unitronics offers a number of video tutorials and webinars that can be found on this site and on YouTube. They're worth your time. Also, review the Help file that came with VisiLogic - it's very useful.

Technically, it's not....it's just free from the PLC's maker.  Unlike many other PLC makers, who can charge a fortune for the means to program their units.

Perhaps I'm wrong, but I thought the OP was referring to the program in his PLC.

Apparently I was lost in a cloud and was imagining that the OP needed to change the timer within ladder and not directly from the HMI (as was clearly stated). I don't think I got enough sleep last night. Thanks @Gabriel Franco for helping the OP from being led astray.

This is where it's at on my computer:

Be sure you have explorer set to show hidden files if you're looking for it in Windows File Explorer.

[V570 info mode , flash memory, how to use.]

When downloading the project, you have the option of "burning" the project into flash (nonvolatile) memory. This would prevent the program from being lost if the battery is flat when power is removed. You also have an additional option of burning the "upload project". This allows the project to be uploaded from the PLC to VisiLogic. There is plenty of information about this in the Help file.

[Something to take into account while developing a project and using alarms on Visilogic.]

Good info, Fernando! Thanks for taking the time and trouble to document this properly.

[Can we use same project for different PLC and HMI?]

Generally yes. The restrictions are (off the top of my head) you can't convert directly between color and monochrome HMIs, Vision & Enhanced Vision products, or Samba and anything else. Since the V430 and V560 are both color HMI and Enhanced Vision, you should be good. However, you will have to convert all your I/O addressing, but that isn't difficult - just do "Replace Operand".

You will have a problem with screen resolution, however. You will need to move or convert your graphics to fit on a 320x240 pixel screen. Your V430 has a 480x272 pixel screen. It will let you convert, but every screen element beyond 320x240 will be deleted when moving from V430 to V560. Just do all your HMI work before converting in the Hardware Config.

[Sending Email when connected to industrial PC]

In my experience, the wired Ethernet and WiFi Ethernet on a PC default to different subnets. Have you inspected both addresses to confirm they're on the same subnet? Easiest to enter IPCONFIG in a Command window.

[OS version's]

There's another option - that I haven't personally tried, but should work - is to create a CLONE file on an SD card using VisiLogic and the correct firmware associated with that version of VisiLogic. Then load the clone on the PLC via INFO Mode. The PLC should then have the latest firmware and the program loaded.

Of course, the OP has never volunteered the PLC model, so it may not have an SD card slot.

[Communication open and after some time "Error cannot communicate with the PLC with the specified unit ID""]

Is it possible to send the data directly to a server instead?

Of course - that's what a SCADA does. I have several customers that use SCADA to collect data from PLCs that I have programmed. It works very reliably.

Be sure you have reasonable values set as Power-Ups for SI 101 - 106, as applicable.

But after a certain time the "listing of files" stop and the following error message « Cannot communicate with the specified UnitID  » is displaying. After this happen, it is impossible to communicate anymore with the device I have to unplug the ethernet cable and plug it again to be able to communicate with it.

SI 103-106 should help with this. This allows the connection to drop after the specified time period (note the the time units are 100ms). I usually put in 10 or 20 for this.

Sounds like you need a PID loop. There are examples that came with your VisiLogic installation.

[You CAN Copy/Paste between projects, but not quite as easily as you hope. Here's how.]

It's not that important, just one of many little gripes that sometimes cause more teeth grinding than desirable.

To me, this is the one feature above all others that I most want to see implemented in VisiLogic. The ability to have two projects open side-by-side and copy & paste between them would save me a ton of time.

So the question arises....why can't this be done with ladderwork?  A quick play reveals that the text is being copied as text, in that you can put it into any sort of text based file.   But as to why the same sort of thing can't apply to memory for clipboard use for whatever data layout/construction is used for ladderwork etc is beyond my puter knowledge.

Because in your example you are using the Windows Clipboard that is built into Windows. It understands text and some graphics files, but nothing else. To copy ladder functions would require an application-specific memory space shared between two instances of VisiLogic. However, each instance of VisiLogic runs in its own memory space and the operating system prevents the sharing of information.

You can copy ladder functions by copying them in one project file, closing that file and opening another then pasting.
