Kepware Knowledge Base: Solution
Error Received Block Length of 1 does not match expected length of 2 for address 10048 on device 07.1-1-34
Last Update: 11/12/2018
Problem:
Reading data from the device returns more registers than requested.
Possible Cause:
This error typically occurs when trying to read data from a flow model controller/RTU with standard Modbus. These devices have address configurations where a call to a single Modbus register (typically a 16-bit data type) will return a 32-bit data type.
Solution:
Select the correct model type or driver for the device.
