Issue with Reading String tags from Netlink S7 Driver

Ignition
1

Hi

I'm trying to read a string tag from Netlink convertor, which gets the data from Sinumerik Controller. I'm using S7-300 driver in Ignition to connect to Netlink. But the tag shows Bad. I'm able to read other datatypes. I get this error only with String type. I use the format ns=1;s=[PLC_Name]DB500,STRING28.24. Any suggestions?

Are the first two bytes correct for the max length and current length? Those are required for IA's string support.

Thanks! @pturmel

In the Netlink, those 2 bytes were disabled. Now it works.
