FieldTalk Modbus Master Library for .NET

MbusMasterFunctionsreadInputMod10000 Method (Int32, Int32, Int32)

Modbus function 4 (04 hex) for 32-bit modulo-10000 long int data types, Read Input Registers as modulo-10000 long int data.

Namespace: FieldTalk.Modbus.Master
Assembly: FieldTalk.Modbus.Master (in FieldTalk.Modbus.Master.dll) Version: 2.15.2-eval+3d8362b4bb861c05760d48b11d303e954bb8597c

Syntax

C++

Copy

public int readInputMod10000(
	int slaveAddr,
	int startRef,
	int[] int32Arr
)

Public Function readInputMod10000 ( 
	slaveAddr As Integer,
	startRef As Integer,
	<OutAttribute> int32Arr As Integer()
) As Integer

public:
int readInputMod10000(
	int slaveAddr, 
	int startRef, 
	[InAttribute] [OutAttribute] array<int>^ int32Arr
)

Parameters

slaveAddr: Type: SystemInt32
Modbus address of slave device or unit identifier (Range: 1 - 255)
startRef: Type: SystemInt32
Start reference (Range: 1 - 65536)
int32Arr: Type: SystemInt32
Buffer which will be filled with the data read. The length of the array determines how many values are read (Range: 1-62).

Return Value

Type: Int32
BusProtocolErrors.FTALK_SUCCESS on success or error code. See BusProtocolErrors for possible error codes.

Remarks

Reads the contents of pairs of consecutive input registers (3:00000 table) representing a modulo-10000 long int value into 32-bit long int values and performs number format conversion.

Note
Modbus does not know about any other data type than discretes and 16-bit registers. Because a modulo-10000 value is of 32-bit length, it will be transferred as two consecutive 16-bit registers. This means that the amount of registers transferred with this function is twice the amount of int values passed to this function.

Note
No broadcast supported
