MbusMasterFunctionsconfigureBigEndianInts Method (Int32)

Configures 32-bit int data type functions to do a word swap on a per slave basis

Namespace:  FieldTalk.Modbus.Master
Assembly:  FieldTalk.Modbus.Master (in FieldTalk.Modbus.Master.dll) Version: 2.15.2-eval+3d8362b4bb861c05760d48b11d303e954bb8597c
Syntax
Copy
public int configureBigEndianInts(
	int slaveAddr
)

Parameters

slaveAddr
Type: SystemInt32
Modbus address of slave device or unit identifier (Range: 1 - 255) A value of zero configures the behaviour for broadcasting.

Return Value

Type: Int32
BusProtocolErrors.FTALK_SUCCESS on success or BusProtocolErrors.FTALK_ILLEGAL_ARGUMENT_ERROR if argument out of range
Remarks

Modbus is using little-endian word order for 32-bit values. The data transfer functions operating upon 32-bit int data types can be configured to do a word swap which enables them to read 32-bit data correctly from a big-endian slave.
