I'm new to EtherCAT/TwinCAT. I have a slave device connected to Master. I can read data with an ADS Client from the slave device if I create a variable in my PLC and link that variable to a value on the slave. Is there a way to get a value from the slave without having to create a PLC variable? I'd like to be able to read and modify multiple objects on the slave without having to create a variable for each in the PLC.
Read values through TwinCAT ADS without PLC variable declaration

In order to enable this functionality all you need to do is Enable ADS Server on the EtherCAT device that you are trying to access.
Making ADS IO symbols available
There are a few setup steps that are required to make this work, but it is reasonably straight-forward.
Where to find 'Enable ADS Server', 'Create Symbols' and ADS Port
Example Symbol path in the IO device list
