Complex bus modules
Complex bus modules are a group of I/O modules that significantly exceed
the functional and application range of the input and output modules de-
scribed in the IEC-61131. Configuration/parameterization software is usu-
ally necessary for their use and/or there are special function blocks available.
The Bluetooth
®
module belongs to the group of complex bus modules.
Configuration mode
Operating mode of the WAGO Bluetooth
®
module in which the module can
be configured. In this mode, there is no data exchange with other Bluetooth
®
devices. It can, however, conduct a wireless search for Bluetooth
®
devices
within range.
Confirmed service

execution from the executor.
Connection
Presence of at least one transmission channel between devices that commu-
nicate with each other.
Control byte
For this module: A specific byte of the cyclic process image output (PIO)
containing protocol information for acyclic services (register communica-
tion, parameter channels).
Coordinator
A device that also performs administrative tasks in addition to data transport
in a device network. An example of this is a Bluetooth
