Note: Remember to set Input Tag to ‘ True‘ on the right column for the PLC INPUT tag (i.e. Note: Noticed the difference for address format in Ecava IGX SCADA for different data types, by comparing the screenshots above. Then, you will require to create the tag with address “DB1.DBX.0.0” in Ecava IGX Project Editor. While for Data Blocks, the address format in PLC config for Boolean tag in Data Block is “0.0”. For example, PLC input Boolean tag with address “%I0.0”, will be created as Boolean tag with address “I.0.0” in Ecava IGX. The address formats will be as shown below. Next, click on the device created on the left menu, and you can now start to create tags accordingly to the PLC tags. You are encouraged to set the same polling rate value for both PLC and SCADA configuration. Note: Column ‘Timer’ refers to the device polling rate. After that, Create a new device under the port, and select ‘Profinet’ from the drop down list for Driver protocol. Click on ‘IO Driver’ on the left menu and add a new IO Port with the corresponding IP address (refer to previous training). Now let’s add them accordingly into your SCADA project.Īdd Data Block tags in Siemens TIA PortalĪdd PLC tags in Siemens TIA Portal SCADA Tag ConfigurationĬreate a new project using Ecava IntegraXor. By doing so you can avoid adding unnecessary burden to your system.įor instance, the PLC tags listed as the below screenshot of TIA Portal will be the required tags for SCADA system. Hence, the best practice is to create ONLY the required tags in SCADA. Most of the time we will not require every single PLC tag to be involved in SCADA operation. Proceed to open a PLC program, in this case we are using Siemens PLC S7-1200, so we will open the program in TIA Portal software by Siemens. Basically, we only need to focus on the tags and addresses. PLC Tag Configurationįirstly, we will start from the PLC part. Let’s move on further from our previous topics and step in to detailed communication between SCADA and PLC, in this training we will be using Siemens PLC S7-1200 over Profinet protocol.
