To gain some time, I created an Excel file with macro. It runs like this :
1. I create the IO configuration in SRS.
2. I export the IO configuration to CSV in SRS (It is a little bit hidden) :
3. In my Excel file, I import the CSV data.
4. I created a sheet where I can link my signal name and a physical link.
5. I "just" create a macro that rewrite the signal declaration sentence in the *.dtx file of my program, like :
<Data name="diMyDigitalInput" access="public" xsi:type="array" type="dio" size="1">
<Value key="0" link="J206_EtherCAT\Box_1_(X20BC00G3_ST1)\%I26" />
</Data>
Copy paste all these declarations in the *.dtx file, and your signals will be assigned quickly in SRS. Very helpfull when you have thousands of signal to link to physical IO
