Since the cost of a 1784-KTx module (or any other network module) is so high, you will save money in the long run.

RSIchan = DDEInitiate(“RSLinx”, “testsol”) This is the destination of the data that will be read by the macro. This macro assumes that there is a worksheet created and saved as RSLINX.xls and with sheet DDE_Sheet . Reading data from a PLC via DDE requires a macro like the following. Using Macros (as contained in the RS Linx Online reference): This can be done in two ways using a DDE link and using Macros.Ħ. Using direct DDE link to import data to Excel. Select a cell in Excel sheet and enter the following formula:ħ. We need to start MS Excel and tell it what the topic is and we are set. We are now ready to start a DDE communication. Then associate this topic with the PLC by clicking on the PLC name on the Data Source tab of the same window then click apply.ĥ. To do this, go to DDE/OPC>Topic Configuration. You will need to configure a topic in RSLinx. Before you proceed, check to make sure that the PLC is online. To do this, in RSLinx click on Communications>Configure Drivers>Ethernet Devices. Simply go to Control Panel>Administrative Tools>Services and enable Network DDE and Network DDE DSDMĢ. Open up RSLinx and configure the drivers so that the PLC can be seen online. Enable DDE communication in the computer. Ensure that the PLC and the computer are connected to the Ethernet. Here are the steps required to achieve this goal:ġ. DDE can be used to exchange data between two programs. The data contained in the PLC resgisters can be imported to Excel using Dynamic Data Exchange (DDE). For an industrial engineer, sometimes there arises a need to import process data to a computer for manipulation.
