MAC ID
(Media Access Control Identification)
The MAC ID of a device is its hardware address. Bluetooth
worldwide, unique identification of a specific Bluetooth
Mailbox
I/O modules with Mailbox functionality have an acyclic communication channel
(Mailbox) in the process image. The data exchange between I/O module and
application can be significantly expanded over this channel without enlarging the
process image. Depending on the module function, the remaining cyclic data is
valid and available during mailbox communication.
Mailbox interface
The Mailbox interface is an interface for executing acyclic services using the
process image (PI).
Master
In a device network, the master performs administrative tasks. For this I/O
module: The 750-644 I/O module that is assigned the role of master, organizes the
piconet and connections of up to 7 slaves.
Mirroring
For this I/O module: Received data is returned without change, permitting a
simple function test of the interface.
N
Net Forming
Generally: "Net forming" is the configuration or establishment of a network.
For this I/O module: All steps including the device configuration that are
necessary for the successful establishment of connections between devices.
Node
A node is a contiguous structure of one or more input/output units that can be
addressed via a local header-end (e.g. a WAGO fieldbus coupler/controller) as a
network.
O
Offset
For this I/O module: Offset in the process image beginning with the 3
(after the control/status byte and internal byte).
