Which PLC are you using? If it has an SD card slot, that might be your best option.
-
You're not calling the subroutine "Run logic" in your Main Routine (which you ill advisedly renamed to "Inputs").

Updating things will likely lead to all sorts of problems...
I totally agree with Ausman and NEVER upgrade the firmware of a working system. However, it's not likely to hose things, but my motto is the same as the engineer's creed: "if it ain't broke, don't fix it".

If you have access to Netflix, find the series "Easy", go to Season 1 Episode 3 about a minute in.

have a look at using Edit/Export Operands Descriptions which will give you a perhaps more easily interpreted Excel file
This will NOT provide the values of those operands, however.

Do you see a download link in my post just above?

As a newbie here can you tell me how to identify if the settings are being saved as registers?
That is a HUGE program. It would take hours to go through it in detail. You will need to identify the settings you're asking about.
As a general rule, any value entered from the HMI is either stored in a register (or Memory Bit) or a Data Table. Both will be retained as long as either 24v power is applied or the battery is good. Review the Help file regarding Operands to familiarize yourself with Unitronics PLC operational memory. If you have any concerns, then do as Gabriel Franco suggested above.

is it possible to get in my ladder program the "Information Mode-->IP parameters" values in order to Initialize the TCP/IP Card with them?
The way you set the IP parameters in ladder is to use the TCP/IP Card Initialization Function Block. In that function block you can hard code the IP parameters with actual numbers that do not change, or you can enter MI addresses which allow you to change the IP parameters at any time by changing the values in the MI vectors. You can change those values via HMI or enter the values through INFO Mode. Once you have entered the values into the MI vectors, then the PLC will retain them unless the battery dies with power removed from the PLC (battery lasts about 10 years).
You can also set the IP parameters directly via INFO Mode if there is no TCP/IP Card Initialization Function Block in ladder. Even if there is a TCP/IP Card Initialization Function Block, you can change the IP parameters via INFO Mode, but they will only stay in effect until the PLC is rebooted (if the FB is activated by SB 2).
-
You've lost me now. Maybe you could post your program or explain again in different words what you're trying to do.
-
If you initialize the TCP/IP card with MIs, then you only need to enter the data once, not every time you start up. You can also enter the MI data through INFO Mode if you wish instead of with HMI user input.

Do you have the .vlp files?

The Snap-In I/O module snaps directly onto the back of the V570 PLC. It's a convenience. The I/O Expansion modules offer more flexibility and a greater number of I/O points but must be mounted on a DIN Rail. Otherwise there isn't much difference - the biggest difference being that the I/O expansion modules have lights for each digital I/O which can make troubleshooting a bit easier.
Your first task in identifying I/O modules is to list all your needed I/O points, both digital and analog, and any communication requirements.

P.S. i also saw the MI option but it would put unnecessary complexity to the ladder program (need to have two modes in start up etc.).
What unnecessary complexity do you mean and what are the two modes in startup you're referring to?

Moved to the correct forum.

I see a "play" bar now, but still no video
I see a download link for a .mov video. Sheesh!

Downloading a program to the PLC does not disturb the existing memory.

My first step is to write the simple code to set the password on an sd card so I can create images of or PLC's for backups.
This sounds like you misunderstand how the SD card password works. It's not part of the SD card - it's in the program you want backed up BEFORE it's downloaded to the PLC. If you have the .vlp files then you will be able to do the backups by adding the Set SD Password FB to each program and re-downloading to the PLCs. If not, then you won't be able to do the backup.
My best suggestion for learning is to watch the Unitronics training webinars and reviewing the example programs that came with your VisiLogic installation. After that, practice, starting with simple projects.

I’ll try again:

Is the video visible to anyone else? It shows up on my phone, but not my desktop.
-
I was watching a dopey TV series on Netflix and what should my eyes behold? Our very own Unitronics V570 controlling a coffee roasting machine. This appears to be a real place - Dark Matter in Chicago. Any forum members in Chicago that can verify?
-
Good luck! Also note that there are example projects that came with your VisiLogic Installation, located in the help menu.

I downloaded the BETA because honestly it was the 1st one to be recommanded at the website, given it's the latest version of Visilogic.
@Cara Bereck Levy, has there been a response to the request that this be changed?

I'm assuming the guy in the tutorial isn't plugging any hardware either
That would be a bad assumption. The Communication selection of the Connection dropdown is communication WITH THE PLC. You are getting that error because you have no PLC connected to VisiLogic.
26 minutes ago, chay said:I'm still learning the ways through visilogic, so I was planning on just starting on a simulation
There is no simulation software for Unitronics PLCs. Their philosophy is that their software is free and their PLCs are inexpensive enough that you can download their free software and purchase a PLC for less that you would spend on other manufacturer's software alone. You should be able to find a Unitronics Samba PLC for $300 or less and it programs the same way as all the Unitronics Vision PLCs using VisiLogic.
I think you'll find VisiLogic to be a joy to work with. It's intuitive and powerful. Pony up for a PLC and have some fun.

We need to know which PLC, what version of VisiLogic, what communications method, and what physical connection you are using. It would also be helpful to know if you've tried other connection methods and if you were able to connect previously, and if so, what changed? Also, are you trying to connect to a new PLC or one that already has a project loaded?
