MbusMasterFunctionswriteMultipleMod10000 Method (Int32, Int32, Int32)

Modbus function 16 (10 hex) for 32-bit modulo-10000 long int data types, Preset Multiple Registers/Write Multiple Registers with 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
Copy
public int writeMultipleMod10000(
	int slaveAddr,
	int startRef,
	int[] int32Arr
)

Parameters

slaveAddr
Type: SystemInt32
Modbus address of slave device or unit identifier (Range: 0 - 255)
startRef
Type: SystemInt32
Start reference (Range: 1 - 65536)
int32Arr
Type: SystemInt32
Buffer with the data to be sent. The length of the array determines how many values are written (Range: 1-61).

Return Value

Type: Int32
BusProtocolErrors.FTALK_SUCCESS on success or error code. See BusProtocolErrors for possible error codes.
Remarks
Writes long int values into pairs of output registers (holding registers, 4:00000 table) representing a modulo-10000 long int value and performs number format conversion.
Note 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 Note
Broadcast supported for serial protocols
