Tag quality is good but values are zero. got bad address in block error kepware EX6

In kepware there are energy meters tags showing tag quality good but values are shown as zero. All of changes in setting like reducing block size, recreated channel and devices, restarted kepware number of times we got bad address in block error. kepware error guide saying below reason,

Possible Cause:
The driver attempted to read a location in a PLC that does not exist, perhaps out of range. For example, in a
PLC that only has holding registers 40001 to 41400, requesting address 41405 would generate this error.
Once this error is generated, the driver does not request the specified block of data from the PLC again. Any
other addresses being requested from this same block are considered invalid.

Kindly anyone post a solutions for the above problem.
