eWriteAddress

Write one device register value, specified by address.

Syntax

LJM_ERROR_RETURN LJM_eWriteAddress(

int Handle,

int Address,

int Type,

double Value)

Parameters

Handle [in]

A device handle. The handle is a connection ID for an active device. Generate a handle with LJM_Open or LJM_OpenS.

Address [in]

The address that specifies the Modbus register(s) to write. Addresses can be found throughout the device datasheet or in the Modbus Map.

Type [in]

The data type of the value:

Type	Integer Value
LJM_UINT16	0
LJM_UINT32	1
LJM_INT32	2
LJM_FLOAT32	3

Value [in]

The value to send to the device. The input data type is a double, and will be converted according to the Type input.

Returns

LJM errorcodes or 0 for no error.

Remarks

For an alternate function using a name rather than address, see LJM_eWriteName.

Example

Write a value of 2.5V to the DAC0 analog output.

C

int LJMError;
// handle comes from LJM_Open()
LJMError = LJM_eWriteAddress(handle, 1000, 3, 2.5);
if (LJMError != LJME_NOERROR) {
    // Deal with error
}
