Elements

Overview of all frame elements.

Element	Size	Type	Description
ClientDataEnabled	variable	string	Data streaming enabled ("true" / "false")
ClientName	variable	string	Name of the connected client (from GET_DEVICES identity)
ClientNo	variable	string	Client number
ClientType	variable	string	Type of the connected client (e.g., "app", "hub")
CRC32	4 bytes	uint32	Integrity checksum. See CRC32
DATA	variable	raw bytes	Signal value, size per DTYPE
DeviceCount	1 byte	uint8	Number of device entries in the frame
DeviceName	variable	string	User-defined device name
DeviceType	variable	string	"server" or "hub"
DTYPE	1 byte	uint8	Datatype code (0x00–0x09). See Datatypes
FWVersion	variable	string	Firmware version
HWVersion	variable	string	Hardware version
LibName	variable	string	Library name
LibVersion	variable	string	Library version (e.g., "6.0.0")
MasterSlaveConfig	1 byte	uint8	0x01 = master, 0x02 = slave
Parent	variable	string	Parent device in topology
RestartFlag	1 byte	uint8	0x00 = normal, 0x01 = first frame after restart
SchemaHash	2 bytes	uint16	CRC16-CCITT over signal schema. See Schema Hash
ServerRestarted	variable	string	Whether server restarted since client connected
SlaveID	1 byte	uint8	0x00 for master; device-specific for slaves
StatusByte	1 byte	uint8	Device/hub status. See Status Codes
StatusPayload	4 bytes	raw bytes	Status-specific data
SymbolID	2 bytes	uint16	Zero-based signal index (matches B0 order)
SymbolName	variable	string	Signal name
Timestamp32	4 bytes	uint32	Conditional: only if TimestampMode > 0
Timestamp64	8 bytes	uint64	Conditional: only if TimestampMode > 0
TimestampMode	1 byte	uint8	0 = none, 1 = micros, 2 = UNIX

All string fields are null-terminated.
