MbusMasterFunctions.writeMultipleMod10000 Method (Int32, 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.

[Visual Basic]
Overloads Public Function writeMultipleMod10000( _
   ByVal slaveAddr As Integer, _
   ByVal startRef As Integer, _
   ByVal int32Arr As Integer(), _
   ByVal numRegs As Integer _
) As Integer

[C#]
public int writeMultipleMod10000(
   int slaveAddr,
   int startRef,
   int[] int32Arr,
   int numRegs
);

Parameters

slaveAddr: Modbus address of slave device or unit identifier (Range: 0 - 255)
startRef: Start reference (Range: 1 - $10000)
int32Arr: Buffer with the data to be sent.
numRegs: Number of values to be sent (Range: 1-50).

Return Value

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 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 Broadcast supported for serial protocols
