dm_modbus_read_int32 Function

public function dm_modbus_read_int32(modbus, address, value) result(rc)

Reads 4-byte signed integer from input or holding register, depending on the address, and returns result in value. If the address is not in input register or holding register range, it is interpreted as a holding register address.

The function returns the following error codes:

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

Arguments

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

Modbus RTU/TCP type.
integer, intent(in) :: address

Address to read from.
integer(kind=i4), intent(out) :: value

Value read from register.

Return Value integer
