The only reason to re-install RSLinx is to get a newer version.

So, to upgrade from 'Lite' to any other version, all that is necessary is to install the activation. One thing to note here is that there is no difference in the program itself - just how it responds to the activation (or lack of it). Each of these have different capabilities. Depending on how much you paid, after activation RSLinx will identify itself as 'single node', 'OEM', 'professional', or 'gateway'.

You will need the RSLinx Classic or some other OPC Server software to do this. There are various versions of RSLinx available and not all will work with Excel.
If, on the other hand, you buy RSLinx separately, then you will get a master disk (activation) with it. RSLinx is an OPC Server which communicates with the Rockwell PLC and facilitates the movement of data to and from the PLC to displays, laptops and in also to Microsoft Excel. To check if you are using unsolicited messages, go to the DDE/OPC dropdown in RSLinx Classic. Gateway supports remote OPC clients and multiple controllers. Both Single Node and OEM must reside on the same PC as the client software. Single node is limited to one controller while OEM allows multiple controllers. Port 44818 is needed only when a user wants to utilize unsolicited messages. You can use the DDE function to initiate a dynamic data exchange (DDE) conversation with another application, request an item of information from that application, and display that information in a control on a form or report. RSLinx Classic Lite does not support OPC, whereas the other three versions are DDE/OPC servers. Then in the General tab of the Options pop-up, uncheck the option Accept UDP Messages on Ethernet Port.
RSLinx will function with the programing packages without an activation and in this mode it identifies itself as 'Lite'. To disable Port 44818, go to Options in RSLinx Classic. It is included with the programming packages but no activation (master disk) is included. When you buy another package, say RSLogix5, you get another master disk with a different activation which you must install in order to use the new package. To setup the communication you must configure a DDE/OPC Topic and point it to the PLC controller. The activation (master disk) you got with RSLogix500 is only good for that package. What the RSLinx Classic does is in rough words connect to the PLC over Ethernet/IP (or other communication protocol) and bridge the data as OPC server, which can be reached from OPC Clients. M_SynchronizingObject.BeginInvoke(PolledAddress.dlgCallBack, z)Įnd Sub and it works thus closes the topic for me.Each different software package from RSI requires a separate activation. PLCAddress = PLCAddress.Substring(m_OPCTopic.Length + 2)ĭim x As New .PlcComEventArgs(ReturnedValues, PLCAddress, 0) If m_OPCTopic IsNot Nothing AndAlso Not String.IsNullOrEmpty(m_OPCTopic) Then

So subscriptions work there is sth wrong with callbacksĪfter studing the code for a little I have found the following conditional in SubscriptionHandler.vb in SubscibedDataReturned subĬode: Private Sub DataChangedCallBack(ByVal clientHandle As Object, ByVal requestHandle As Object, ByVal values() As Opc.Da.ItemValueResult)ĭim ReturnedValues() As String = ĭim PolledAddress As PolledAddressInfo = DirectCast(values(i).ClientHandle, PolledAddressInfo)ĭim PLCAddress As String = values(i).ItemName
Also Active DDE/OPC Topic/Item List shows that desired tag is being read from a PLC. When this happends I can see in RSLinx Classic: OPC Group Diagnosctics that groups are added properly and Subscription Packets are flowing. RSLinx Classic OEM or higher is required for these application types.

It does not support applications developed for the RSLinx Classic C API, or direct drivers in HMI applications. OPC and DDE interfaces are supported, but to only one device. Result: works great, I try the newest relase v3.97c and the same: no updates, nothing happends on the screen. RSLinx Classic Single Node includes the required functionality to supply communication services for all Rockwell Software products. I try the previous version 3.7 of AdvancedHMI and follow the same pattern. Main Forms opens but the BasicLabel is not updated with the PLC read value, nothing happens, no any faults.
Where can i buy rslinx classic with opc dde driver#
I open a new basic AdvancedHMI project, add communication driver OPCDaCom and set its all neccessary parameters then add any HMI controls like BasicLabel for example and set a PLCAddressValue and build and run application. For application development I am using: RSLogix Emulate 5000 to emulate PLC, RSLinx Classic as OPC server and wanted to try AdvancedHMI v3.97a.
