Support Questions / OPC connection to remote server

« on: August 22, 2016, 11:33:07 AM »

using OpcDaCom, I am tryint to connect to an OPC server on a remote server the server address is 10.224.220.109 using OPC expert https://opcexpert.com/ I can connect by just adding the address of the opc server and it finds Kepware.KEPServerEX.V5 and allows me to connect to it. Why can't I connect to it with Advanced HMI? I have tried changing opcda://localhost to remotehost, the IP address, and several other thnigs but nothing seems to work. What am I doing wrong?

Support Questions / direct reading and writing to OPC in AHMI

« on: August 05, 2016, 11:28:51 AM »

I know it's here in the forum but after 2 days searching I give up. Could someone point me to how to read and write to an opc server in AHMI without using a control, I have an need in my app for direct reads/writes to OPC and to/from a database, I use controls in some places but the direct reads and writes are easier. I found them here once, but now I can't find them and with 5TB of code on my hard drive I can't find it there either, any help would be appreciated, thanks in advance
Loving AHMI!!!!
and have posted about it more than once on FB LOL
ps only need the direct read and write code for OPC, I have the database handled, lol

Support Questions / DataSubscriber 2

« on: February 04, 2016, 01:31:10 PM »

OK I'm going to try this again. My company just upgraded their server and I can't send or receive any attachment period so I'll have to cut and paste the code. The problem I am having is I'm trying to add items using a loop and the code DataSubscriber21.PLCAddressValueItems.Add(New AdvancedHMIDrivers.PLCAddressItem() With {.SubscriptionID = CInt(records(x, 3)) - 1, .PLCAddress = records(x, 1)}) where Records is a string array containing the address I want to look at. I'm using the OPC driver and the program works fine except for one thing, It is taking 4.5 hours to add 772 items to the subscriber? I also just added this code a = e.PlcAddress.ToString & " = " & e.Values(0).ToString & "; subscription ID = " & e.SubscriptionID & vbCrLf & TextBox1.Text and I think that it has shown me what the problem is, but I don't know how to cure it. It seems that when you add an Item to the datasubscriber, it is using soe type of recursion to add it? anyways what I see is an output to the textbox of item 1 printed, item 1 printed, item 1 item two printed, item 1 printed, item 1 item 2 printed, item 1 item 2 1tem 3 printed, ant it progresses that way for each item I add. I'll paste all the code from main form below, the module named tracking only has 1 textbox on it and the data file is comma delimited and consists of two items per line of 772 lines, I'll include a 12 item list at end for sample purposes, but you'll have to make your own as OPC will have to be working for this example to run and the tags will have to exist on that opc server. Could someone tell what is going on and how to fix it. Aslo I've been programing since dartmouth basic came out so please lay off my style comment on on actual errors in code, not how I program. LOL
