The source text is transmitted to ibaPDA via the PC network (Ethernet TCP/IP) by an OPC or OPC UA server. You can set the configuration in the I/O Manager under the node OPC or OPC UA. In the OPC client or OPC UA client module, Analog tab, the source text is configured with the data STRING. To divide the text from the OPC tag onto individual text signals, a module Text splitter must be configured per source text under the Virtual node.
