<div class="markdown_content"><p>Hi,</p> <p>I use a WAGO PFC200 controller with MODBUS RTU on the integrated port. There are 8 damper valves for ventilation and 6 energymeters that are connected to the fieldbus.</p> <p>Since I have to do a lot of mapping of the raw I created some function blocks but I cannot figure out how to do a specific addressing for an identifier.</p> <p>There is Modbus objects - one of them in my case is "Energymeter_1" and the datatype is "typEnergymeter_1_rtu".</p> <p>Therefore when I want to access a variable from "Energymeres_1" structure I write the following - "Modbus.<strong>Energymeter_1</strong>.L1_voltage".</p> <p>Since I have 6 energymeters is it possible to create a variable that is an input for the function block and use the variable to change the energymeter I reference in each instance of the function. The variable should be written instead of the <strong>bold</strong> text on the above line.</p> <p>"Modbus.<strong>var_for_energymeters_number</strong>.L1_voltage - it should look like similar to this.</p> <p>I do not know if this addressing is possible, I have tried to play with pointers but with no success.</p> <p>Best Regards<br/> Konstantin Kolev</p></div>
