dm_modbus_write_registers Function

public function dm_modbus_write_registers(modbus, address, data, n) result(rc)

Writes many registers to address. The size of argument data determines the number of registers to write, unless optional argument n is passed. The function uses the Modbus function code 0x10 (preset multiple registers).

The function returns the following error codes:

  • E_BOUNDS if argument n is larger than size of data.
  • E_INVALID if argument data is invalid.
  • E_MODBUS if writing the registers failed.
  • E_NULL if the Modbus context is not associated.

Arguments

Type IntentOptional Attributes Name
class(modbus_type), intent(inout) :: modbus

Address to write to.
integer(kind=u2), intent(inout) :: data(:)

Register values (unsigned).
integer, intent(inout), optional :: n

Number of registers to write on input, number of registers written on output.

Return Value integer
