SDO wont allow indexes greater than 4 bytes

2020-02-27T22:47:49.025000Z

Hello,

I'm using Codesys provided by Festo and and using a Wago EDS file which have a few subindexes for specialty modules which are anywhere between 5 and 8 bytes as defined in the EDS file.

However, when I add the EDS file in the PLC configuration in Codesys, it only shows those indexes which are up to 4 bytes and the ones between 5 and 8 bytes are simply not shown. Is there a setting to modify this? Or can we maybe edit the *.cfg file or the library file to modify this setting. Please advice.
