WAGO-I/O-SYSTEM 750
®
750-644 Bluetooth RF-Transceiver
Segment
For this I/O module: Part of the process image (PI). The process image is divided
into up to 10 different segments. In addition to segments of a fixed size, e.g. C/S
byte, HS byte and null byte, there are also segments of configurable size: the slots.
The size of a segment is referred to as cut-off.
Signal strength
The signal strength is an indicator of reception quality. The higher the signal
strength, the better the reception.
Slave
A slave is a device that transports data in a Bluetooth
It does not accept any administrative tasks. Opposite: Master.
Slot
For this I/O module: A slot represents a part of the process image (PI) that is
reserved for data exchange with a specific remote device.
SMA
(Sub-Miniature-A)
SMA refers to a special design for coaxial connectors. SMAs are used, for
example, to connect external antennas.
SN
Serial Number
SPP
(Serial Port Profile)
Bluetooth
SSP
(Secure Simple Pairing)
Based on Bluetooth
Status byte
For this I/O module: A specific byte of the cyclic process image input (PII) that
provides information on the system status at run-time.
Subsystem
Part of a whole system with which it is connected over defined interfaces.
T
TCP/IP
TCP is a connection-oriented network protocol for the transport layer (Layer 4) of
the ISO/OSI model provided with relatively secure transmission mechanisms.
Transmission channel
