Dear Experts ,

i am planning to communicate the Schneider drive via Modbus TCP/IP

with S71200.

I can able to get the data ,in Modscan Software 

i can able to read the data in 49001- format integer(Holsding register)

i am using MB client FB blocks

i am getting error Code 8383,&7005,7006

its means i can get the communication from the drive ,but i cant get the data.

i tried the data formats& data length & its not getting the data

issues:

1.How can i enter the data in holding register format

2.What are the parameter needs to check

kindly suggest your feedbacks

 It seems your Data PTR size is not enough because you had defined the DATA LEN higher than the DATA PTR data block. Some screenshots of your blocks will be helpful.

Thanks,

Jay
