[large data table]

Richie,

There is few limitation in the structured Data tables:

1. Max number of the columns: 32 with 100 element(cells when exported to excel) each - 3200element total.

2. The maximum number of operands of any typefor a Read/Write operation is 128.

3. Max memory for all data tables is 122000bytes

That mean

1. Fortable of 10x9999 you can use only “Byte” as a maximum size of the elements

2. Whynot a table of 10 columns and 9999 rows?

Alex,

That relevant only to color models.

For V-120 you should from file menu go to Project>Properties and diable project upload:

Think about not to stop the machine, but use a flying shear

Here is a video for a similar machine:

In this case simple high speed encoder + V-350 is a perfect solution + full automation

[V1040 lost it's memory]

2 suggestions:

1. Download program by selecting "Download All & Burn" (make sure after download SI72=1)

2. Check the battery (SB 8 and SB9 must have "0") and check that battery sitting well in the compartment.. I would replace the battery anyway.

[Visilogic For V1040]

Just want to share with one discovery i found regarding this issue:

I got a new PC. While setting it up I found Google Chrome, what i not really like. I uninstalled it. Then all kind of problems shows up.

- After installing Visilogic - got an error: Run-time error 2006: Invalid tools collection index

- Clicking on hyperlinks in my email - This operation has been cancelled due to restrictions in effect on this computer

- some programs on installation told me that i don't have admin rights, etc.

After brief research I found that non of Microsoft recommendations does not work in this matter and only a solution is to re-install Chrome then if you don't like it or don't want to use it just make IE your default browser.

[MI values not retained]

Do you mean " flash" - is SD card?

If you reload program from SD using "Full cloning" option, Operands values will be definitely overwritten. If so, try download by components: OS, Application, Data tables(if needed), but not Operands.

To get a desired result, store 8000h into Memory Long, then RSH.

According windows calculator the result is absolutely correct.

Is any plans to move to ARM processor?

[Modbus TCP - problem with Master]

It should work,

Some remarks you'll find in the attachment

ModbusIPMaster2.vlp

[Modbus TCP - problem with Master]

I just looked deeper into your code:

All initiate functions have to be 1 scan operation and you set for every scan. The best way is to use SB2 (PowerUp) as a condition

[Modbus TCP - problem with Master]

2 notes:

1. In sub "ModbusTCP master" net 4: Instead SB1 should be SB149 (seems to me just a miss spell)

2. Unitronics will correct me if i am wrong, but ModBus init is recommended to be placed in !Main Routine

[Visilogic 8.6.3]

I'll try to explain my situation and my "dream":

At the moment we have almost 1500 Unitronics PLC installed on our clients sites. This number increases on 150-300 units annually and we are providing maintenance and support for all those PLC's . This include fast response on any clients issue ( mostly through Visilogic debug mode) and frequent PLC application update to the latest version.

For that purpose we are currently keeping few hundreds of all kinds remote connections to our clients networks with Visilogic installed on every remote server.

The "dream" is to have 1 server locating on our host with public static IP.

Server should have visilogic with "multi-threaded visilogic listener" for support and Download Manager for application update.

Each PLC installed on client site will be connected to "multi-threaded visilogic listener". In the "HOST" mode, instead "favorites" visilogic should provide list of PLC's connected to Visilogic with its IP's and named, then user will select 1 unit to debug or download.

Same about application update through Download Manager.

I am well aware about difficulties in developing multi-threaded applications as well that the current Visilogic is based on the ActiveX library, which is not really suitable for such tasks. But Download Manager is based on .Net 4.0 framework.

We already developed a server application (written in Java) for our clients, which provide simultaneous connection between user's SQL server and users PLC's for data exchange. It works pretty well.

Now we are looking for a similar way to improve our support and to automate PLC programs update.

In other words ultimately, we want to make PLC works same way as my PS3, which is connected to PlayStation network and receives all necessary OS updates and connected to game server for on-line play.

One of the options that we considering to automate PLC update is to make a server application which will listen and accept connection from remote PLC's and distribute "clone" files directly to SD card. Than PLC in appropriate time will update itself from SD.

But if Download Manager can do the job, it will save us a lot of time and efforts.

[Visilogic 8.6.3]

Cara, does this is mean that we should expect multithreaded visilogic listener?

If this is true - we need it "yesterday", as well for new Download Manager. This is really hot feature.

Yes, you can establish up to 4 communication channels using Ethernet Sockets 0-3 with independent config setting and you can change configuration of each channel in run time.
