Post subject:  Network Variables without receiver exported GVL

Hi all,

we have found machine with Network Variables configured. But there is no backup of software and no support and we are trying to map the Network Variables to another machine. Still unsuccessfully. Is there any way how to scan NV or how to connect it without imported GVL? We've used WireShark etc. and we know the sum of exchanged data... But when Array of bytes in this size is defined it do not communicate...

THX

I will answer to myself: there is number of items in transfered data and num of data. We have tried to make dummy int declarations and... it communicates. So NV depends on number of variables declared...
