Definition "Advanced Data Identifier"
The "advanced data identifier" has a length of 5 bytes. It consists of an object ID (4 bytes,
format "unsigned long" big endian) and the number (1 byte) of data records required in the
response frame.
Every data record of a historical data memory in the PAC device can be addressed by this
object ID (OID) which is unique in the device. A special entry (or a number of entries which
are inserted in the frame one after the other) can be read.
The highest OID in existence is available for every data memory in associated Modbus
registers (see table "Data memory and associated Modbus registers").
If OID 0x00000000 is requested, the PMD returns the oldest valid OID with the associated
data record. If a non-existent OID (other than 0) is requested, the PAC device returns the
Modbus exception code 0x04. A syntax error in the Modbus frame also results in a Modbus
exception response.
