As of now, all modbus clients that i coomunicate are already ok!

The holding registers with address 40000 to 40015 of each clients are displayed on each data blocks..

But the data from 40000 to 40015 (dbw0 to dbw32 on each data block) are not correct.

The ammonia compressor(modbus client) has a built-in remote panel display.The data on remote panel display must be shown on HMI. But the data that i gather from the data blocks (ex. DB31.DBW0 to DBW31.DBW32) are different from the data on the remote panel display..

is there something wrong in the parameters??

I know that modbus data are in hexadecimal.. In HMI, i set these data as integer. Some data are correct like modbus address 40000 for motor ampere value but the others are not.

thanks.
