Remote DF Modbus/TCP Server won't open TCP connection
AzeoTech replied to SteveMyres's topic in Modbus
I'm not sure. The easiest solution is to simply get a serial to Ethernet converter and have DAQFactory act as the Modbus slave on a serial port, then use the converter to put that comms onto Ethernet on 502. Then you are no longer using Windows networking and all the issues (i.e. firewall, etc) that come with it. You are using Windows serial ports which are quite straight-forward. DAQFactory and Windows won't know that you are then going Ethernet. Since DAQFactory supports any protocol on any transport layer, you can still use the ModbusTCP protocol without having to use a protocol translator, so you are talking a $200 or less device. -
Remote DF Modbus/TCP Server won't open TCP connection
SteveMyres replied to SteveMyres's topic in Modbus
Another curiosity. My remote access is via a Cisco Anyconnect VPN administered by the customer. Wireshark lists the Radmin VPN virtual adapter I use for remote access sites I manage, but does not seem to be aware of the Cisco one. If I could Wireshark the queries, I could see if there's any difference between the DF ones and the Modbus Poll or Baseblock ones. -
Remote DF Modbus/TCP Server won't open TCP connection
SteveMyres replied to SteveMyres's topic in Modbus
OK, so changing the port worked, partially. Can't imagine what could have been added to the DF PC using port 502, but changing to 510 allows both my DF test client and Modbus Poll to connect. However, DF polls successfully and Modbus Poll does not. It times out, even though both clients have generous timeout setting far longer than the typical response delay of 80ms. Baseblock ComTest Pro also times out and claims not to have received a response. DF and the other two clients have all worked in the past. I've been at this point before, as well as the case where all clients I used would work, when the plant SCADA guy could not get a response with Wonderware or Modbus Poll. I'm baffled. - Last week

Thanks Guru, I will do some reading into the web service and hardware you mentioned.
-
Yes, sending the doc would help. Email to support.

It can be done, though for live readings from anywhere you will need to use a web service such as DAQConnect. Having remote people connect into your system directly creates all sorts of security challenges. If all you want to do is collect and graph the data, you may be able to use DAQConnect exclusively, along with a DAQBridge. The DAQBridge would be setup to poll the field loggers and push the data to DAQConnect where you can then keep historical and offer trends to multiple users. No PC would be required. This assumes your field loggers talk Modbus. If they don't, you'd have to use DAQFactory on a PC instead of a DAQBridge.

Set the order of objects in script
Hoyer replied to Hoyer's topic in DAQFactory New Feature Requests
Nevermind, I've found the solution. I move the objects on the same page as I described in method 1.) Thank you for the quick help! Best Regards, Hoyer -
Set the order of objects in script
Hoyer replied to Hoyer's topic in DAQFactory New Feature Requests
Thank you for the answer. These solutions are not OK for me, I'm doing currently the page changing trick and I would like to reduce the number of pages. Visibility is not helping me either as this object has functions and I can't set which is activated with Visibility. It doesn't matter which one is Visible and which one is not, the one which is activated is always which is on top of all the others. I could find out two other possible solutions: 1.) Setting the position (like in an X-Y coordinate system) of objects from script. (This way all objects would be somewhere out of the useful range of the page and the necessary one would be moved to the place where the operator will be able to click on it.) 2.) There is a "Change component's page" option when I click on an object while pushing the Ctrl button. Can this command be done from script? Then all the objects which I don't want the operator to click on would be on a "Page_Bin" and the one which shall be used moves to the other page when the script reaches the given point. Thank you in advance! -
Hello, So I have an application where there are 8 x fieldloggers where each unit is logging 12 x thermocouple data. Ultimate goal is to be able to log live data coming through the fieldlogger. Logging will be in 30 second intervals for for 7 days periods (in rare cases up to 120 days). Some important points are that the system plots to the system time so I can go back and view data at specific date and time in the graph. In addition, to view the graphing data on the web so anyone can view live readings from anywhere. Can this be done through DAQFactory? If so please point me in the right direction to begin. I would Like to work with the express version until it is confirmed that this can be done.

Set the order of objects in script
AzeoTech replied to Hoyer's topic in DAQFactory New Feature Requests
There is not, but you can control the visibility with the "visible" variable which exists on every component. You could also control ordering by putting the components on a different page and overlaying the pages. Then when you set the current page with: page.strCurrentPage = "myPage,my2ndPage" you can control the ordering as it paints one page, then the next, so this: page.strCurrentPage = "my2ndPage,myPage" would paint things differently then the first one. -
scroll bar position
AzeoTech replied to steveandrews's topic in Screen Components and User Interface
Yes, there is a variable in the component called "TopRow" which you can set to the row of data you would like to be the top row in the table. So 0, would scroll you all the way to the top. To scroll to the bottom, set TopRow to the number of rows of data minus the number of rows visible in the component. -
Hi, I have a table with many rows. When the table fills, I would like it to display with the bottom row visible (i.e the scroll bar at the bottom rather than at the top). Any way to do this in code? cheers Steve

Can I set the order of objects on the page in script? I would like to bring some objects to the front when my sequence reaches a given point. Is there a command for this? Thank you in advance! Best Regards, Hoyer

It depends which installer you ran. See here: https://www.microsoft.com/en-US/Download/confirmation.aspx?id=29062

how to know if i use a 32 bit or 64bit database
-
Did you use the 32 bit version of SQL Server?
-
windows 7 64 bit I have a 64 bit system and I created a database on sql server 2012
-
I am on another system
-
Is the database 64 bit or 32 bit? Again, you have to be careful that everything is 32 bit.
-
-
now i'm on windows 7 64 bit with sql server 2012
-
Which LabJack are you using? U12, UE9, U3, U6, T4 or T7. See related information here: https://labjack.com/support/app-notes/usb-communication-failure My first suggestion would be to remove the relay box from the system and see if the problem goes away.
-
Start simple then. Turn off authentication. Make sure you are connecting to a local database and not trying to do this over a network. If you have another tool available, see if it can connect over ODBC. Or, if a Test button is available on the ODBC configuration page, check that. Is the database local?

but i have a Windows 7 32 bit

Remote DF Modbus/TCP Server won't open TCP connection
SteveMyres replied to SteveMyres's topic in Modbus
Wellp, can't test locally. Could try another port, though it hasn't changed since it worked [for me but not for him], but it means I'll have to edit the CTL and resend. That's doable. Oh, and the SCADA guy hasn't physically been local when he's testing but requests have been sent from his WW machines which are local, in addition to using Modbus clients local to him via VPN like I'm doing, and the local ones did no better.
