" Modbus Exception Error".
Modbus Exception Codes are error codes that are returned by a Modbus Slave device when it has detected a problem with a command that it received.
Exception codes can be generated for several reasons, including bad data values, invalid Modbus function codes, invalid register values and more.
In your case, you should use the length wisely as per the register list.
For example, If you are reading Modbus register address as 3000, use the length as 6 or 10 & then cross-check whether data is coming in MODSCAN or not.
