<div class="markdown_content"><p>yes, SP18 has such a functionality. It allows you to access the IO Devices without a predefined mapping.<br/> image something like this:</p> <p>xCh1 := EK1202.iCh1;</p></div>

<div class="markdown_content"><p>I would also like to do something very similar. Is there a way to get the device data using the name rather than mapping to words?</p></div>

<div class="markdown_content"><p>I have tried __VarInfo on the device but couldn't locate the data within.<br/> I also look the iecaccessvar library but not enough documentation there to be able to use that<br/> any idea?</p></div>

<div class="markdown_content"><p>Hi<br/> Im using machine expert from schneider (based on codesys)<br/> I have a device on a modbus ioscanner (a generic device with some io channel added)<br/> Currently I have a function block that I pass the first address of the input and the first address of the output of that device, which I control in that function block.<br/> But to make things nicer I would like to pass only the device name to that function block (type: IoDrvModbusSerial.ModbusSerialSlave). My question is how do I access the data of that device using the device name, so I wont have to map the first in and first out and pass it as parameter to the function block??</p> <p>Do I have to define a device completly instead of a generic device with io channels? if so how?</p> <p>thank you all</p></div>
