Dear Experts,

I had communicate between micro win S7 200 & Schneider HMI GXO 350

I can able to read write through HMI. its working fine.

but I cant able  to use double integer from HMI.

example: I set the set point values via HMI. every time I can  chose my set point.

once I switch off the HMI the all set points goes to Zero.

this is the issues I am facing now.

suppose I selected the double integer from HMI, but the address not available in HMI that VD format.

only having VW,VB,IO,IQ

here I attached the screen short of HMI

I hope you can understand my issues

kindly suggest to proceed
