Support Questions / ModbusRTUCOM driver multiple Nodes not communicating

« on: September 24, 2016, 03:21:46 AM »

Hello Archie ,

With earlier versions before 399 , we could change station address property and communicate with multiple ModbusRTU stations .
Here if any station does not respond , Read write to other stations was not affected , screen continues to show other station registers.

But With version 399 onwards , if any station does not respond within timeout period , communication to alll nodes (stations ) stops .

Trying to find out reason , still no joy .

Nodes 1 ,2,3 ,4 ,5 ,6 ,7 all working ok ...
Now if node 4 stops responding (In real field situation it can happen, that machine may be down), initially 4 ,5 , 6, 7 stop responding , and then 1,2,3 also stop resp,onding .
I tried to debug with Mod R Sim  found that AdvancedHMI stops polling if any one device is unresponsive . Earlier it wasnt this way .

Hi ,

Since long we are with AdvancedHMI and quite comortable with windows forms . I came across some Scada forums saying WPF is better than win forms in terms of presentation and attractive UI developement .
Is that so ?
Can we use AdvancedHMI with WPF ?

Application Showcase / AdvHMI with ModTCP , ASP.net & SQL

« on: February 01, 2016, 01:13:32 AM »

Hi ,

A very basic prelim application trial using AdvHMI as Server connected to ModTCP PLC , SQL server for dataexchange  between ASP.net clients and PLC .

Runs OK to some extent , but lot of further development required to make it Deployable & reliable enough to give it to client.

Open Discussion / Getting VS2013 community edition

« on: May 21, 2015, 09:16:02 PM »

Not an issue with AdvHMI .
But regarding VS2013 community that is needed for working with AdvHMI new versions.
Since long I am trying to get and install VS2013 community . 7 GB download is quite difficult to download , even after downloading extracted versions are corrupt . When rest everything is OK , install fails with error KB2827760 . When searched on net there are host of others who could not manage to get and install VS2013 community .
On this forum any other members facing same issue ? any solution ?

Support Questions / FactoryTalk SE server and AdvancedHMI in same PC talking to CompactLogix

« on: March 20, 2015, 06:07:54 AM »

Hello Archie ,

Would following configuration work ?

I had CompactLogix L32e PLC and  FactoryTalk SE 25 Screen SCADA connected with Ethernet/IP . Both working OK .
On same PC I tested AdvancedHMI on ethernet/IP driver to read/write tags with L32E , works OK (when SE SCADA was not installed yet).

Since customer has purchased only SE and no SQL or Vantage point , I was finding a way out . Every few seconds , I would read few tags from L32E into AdvancedHMI and then INSERT these into SQL table .
Since AdvnacedHMI and SE Scada would be Clients to same L32E , would it be a problem ?
With SE RT licence , RSLinx OPC is not provided else it would have been much easier .

Thanks ,

Support Questions / EthernetIPPLCSLCMICRO and ModbusTCPCom on single Ethernet port

« on: November 20, 2014, 01:21:00 AM »

Hello ,
I want to connect MLX1400 PLC (IP 192.168.0.1 ) and ModbudTCP Controller (IP 192.168.1.1 ) to PC running Advanced HMI application thru single wired Ethernet port on PC .
I added two IP addresses  to single ethernet port , namely 192.168.0.10 and 192.168.1.10 .

I wish EthernetIPPLCSLCMICRO driver IP 192.168.0.10 should talk to MLX1400 PLC (IP 192.168.0.1 ) .

And ModbusTCP driver 192.168.1.10  should talk to ModbudTCP Controller (IP 192.168.1.1 ).

In the driver vb code I could not find where to mention HOST port IP address or port no .

Is above configuration logically possible ? In another two days my hardware will arrive , then I can check this .
Expert advice requested to make it feasible or any other alternative welcome .

Thanks ,

Support Questions / Adv HMI with Mitsubishi PLCs over EtherNet

« on: September 10, 2014, 03:27:41 AM »

Hello Archie ,

By reading Ethernet communication manual of FX3GE PLC (Pls google for jy997d45801d and download , refer page no 65 onwards),
and  by referring various other posts on net , I could communicate with FX PLCs.

I can read 64 registers on each request , writing Registers is also OK.

If you want  to make driver in Advanced HMI for Mitsubishi PLC on Ethernet I can send the code .

My Code is not as robust as AdvHMI drivers , since it only makes a connection , reads / writes data and disconnects , no diagnostics etc .
But it will be useful for developing on the lines of other drivers that you have written .

Support Questions / Previous version S7 1200 Adv HMI ReadAny problem

« on: April 09, 2014, 04:28:48 AM »

Hi,
This previous version can display PLC MW variables read over TCP port from S7 1200 PLC . Writing thru Basic Label is also OK .
But I am unable to get any data by using Readany function
       Dim addr As String = "MW12"
        mw = SiemensPLCsComm1.ReadAny(addr, 2)
        TextBox1.Text = mw(0)
        TextBox2.Text = mw(1)
I always get 0 values even though these register values are correctly displyed on ADV HMI controls like digital panel meter .
I tried various variations of address and number of registers combination , No Joy .
No errors are indicated . When I read buffer returned by the SiemensPLCsComm1 function I can debug that these values are received in the BUFFER . But somehow these dont get populated in MW string array.
Any sugestion what is wrong with above code ? 

Thanks,

Support Questions / AdvHMI V361 ModTCP error 20

« on: February 20, 2014, 09:10:17 AM »

Hi,

I am using AdvHMI V361 ModTCP driver for reading/writing to ModTCP PLC . For a while comm is OK , after some time randomly I get

" com fail " exception 20 at Read function at this line
   
Else
            Throw New MfgControl.AdvancedHMI.Drivers.Common.PLCDriverException("Com Fail - " & result)
        End If
 
What could be the reason & way to solve this issue ?
