[Active Loop and Passive Loop]

So, Why two wire connection is shown in V200-18-E3XB manual if is not supported?

[EX-RC1 wiring topology]

To wire several EX-RC1 and a Vision controller, it should be a "daisy chain" or may I use a star topology?. In last case, which modules should be terminated?

[Programmatically Create Projects]

As the PLC doesn´t run ladder simultaneously, you may use a single subroutine to execute common task passing variables to it as needed and then returning results from it. I´ve used indirect addressing to do so.

 

As Joe mentioned, there is such useful tool to search/replace. In previous visilogic versions, it did not replace operands inside some FB, but guess it´s fixed on current version.

[Modbus TCP/IP Communication between V350er OPLC's]

I´ve used UDP instead of TCP. This way I only need one single socket and connect/disconnect has not to be performed.

[Flyback diode]

It looks appropriate to me. I´m uncertain about then best VR choice, I would choose at least 3 times source voltage.

[signed or unsigned data issues]

You mentioned 2 MIs are whole number, so you must convert those 2 MI to one ML. You may use COPY MEMORY or STRUCT functions.

[CSV and MLs]

After some testing, I found the problem. Both IN parameters (Start of vector and Max vector length) must be ML. Previously I used MI for max vector length and ML for start of vector.

[CSV and MLs]

I am having trouble creating CSV file containing ML values. All values greater than 65535 are truncated to just the lower word, e.g 150000 (hex 249F0)  is saved as 18928 (hex 49F0).

 

Any idea, or is a normal behaviour?

[mask entry]

Alexander, I just update firmware and now mask work as you mentioned.

Original: O/S 3.6 (14), BOOT 2.2 (09), BinLib 1-1.10 (01), Factory Boot 1.3 (07)

New: O/S 3.8 (02), BOOT 2.2 (11), BinLib 1-1.10 (01), Factory Boot 1.3 (07)

[mask entry]

I have one V570 on my desk, so doing tests directly with it.

[mask entry]

It´s not working for my application as you described (V570, Visilogic 9.6.0). I do not notice any difference checking or unchecking this option

[mask entry]

In numeric variable, What "mask entry" is used for?

 

A couple of suggestions for creators, regarding numeric variables:

 

1. An option to "group" digits for display purposes. Large numbers may be difficult to read without such option,i.e 9876543.21 displayed as 9,876,543.21

 

2. Option to show entry limits in keypad, so the user is aware about them.

[HMI screen order]

Use "Load HMI display" function (Under Utils|HMI) connected to SB2.

[Connecting Unitronics V350 to Yaskawa MP 2600]

Matteo, as it is UDP instead of TCP, does not need connect block to stablish comms. If Yaskawa specifically needs TCP, so you need connect to remote IP and port (Checking Ethernet card and socket are initialized) prior trying to get info from slave using any of modbus ip functions.

 

Did you tried modbus ip master example included in Visilogic?

[Connecting Unitronics V350 to Yaskawa MP 2600]

See attached file. It´s the way I communicate with MODBUS IP slaves to get data from them

MODBUS_IP_YASKAWA.vlp

[Data Table Sharing]

You could try MODBUS IP function read/write from/to data tables

 

[EX-RC1 Connection problem *factory program visilogic error*]

Double check:

- Net ID config on both sides: OPLC (Using power-up bit to set ID) and EX-RC1 via switches.

- Comms parameters: comm port, baudrate and so on, both sides too.

- Make sure address switch is firmly selected. I had a similar problem long time ago, just moved switches back and forth, and everything worked fine.

[JZ10-11-R16 : Using a float]

I´ve used GF Signet flowmeter with Jazz and used K factor multiplied by 100 or 1000. For instance, if meter gives 15.43 pulses/litre, I use 1543. This way I obtain a value in litre x 100.

[SD Card Explorer - Corrupting Files / Card]

I have had similar issue writing files from SD Card Explorer while PLC (V1210) is writing csv files or sending email. So, I disable that portion of logic on PLC prior writing files from PC.

[Analog Input]

R16, R16-V, R16L, all of them appear in documentation files and clearly defines analog input differences, however I only see R16 in webpage.

Suggestion for web administrators: Update web page information, as well as comparison tables. I use to get info from there to define which device fits my requirements

[Display ASCII String as centered]

Have you checked if string contains spaces at the end? Extra spaces cause string being displayed left justified instead of centered.

[Protocol Scan Function]

Try this way.

 

Set MI523 = 10 (1 decimal place) and use an ML instead MI to link your weigh value.

 

 

 

 

 

 

 

[Maximum expansion IO modules per adapter]

As I understand the issue, there is a 50 words limitation for local I/O expansión. 16 points digital input or output uses 1 word, so, one can mix any cards as long as they do not exceed such limit.

Am I correct?

 

I tried 6xATC8/AI8 + 1xIO-DI16 + 1xIO-TO16 and calculator shows 100% capacity, but also got same error of original post

[Two MI-s into one ML]

Emil, I tried again Copy Mem and got same results as STRUCT. Probably I made mistake before.

[V130-33-T2 as master to altivar 312 VFD]

Master Start of Vector must be an MI also. FB doesn´t allow you to select MB. Make sure you are using Read Holding Register (03)
