Centralized strain relief to prevent lead damage
The flat-cable design features a Kevlar-reinforced core, to absorb the
tensile loads to which cables can be subjected in tough applications. When
subjected to high tensile loads, this centralized load-relief Kevlar core also
prevents cable leads being damaged or compressed. For maximum signal
integrity, the flat cable design also ensures optimum separation of high and
low voltage conductors.
For more information regarding cable management please look in the cable management
pocket guide (9833 1640 01). In this pocket guide you will find more information regarding cable
management for fixtured and hand held tools and check points before, during an
FIELDBUS
Fieldbus is an industrial network system
for real-time distributed control. It is a way
to connect instruments in a manufacturing
plant, for example Power Focus controllers.
Fieldbus works on a network structure which
typically allows daisy-chain, star, ring, branch,
and tree network topologies. The fieldbus
requires only one communication point at
the controller level, and allows hundreds of
analog and digital points to be connected at
the same time. This reduces both the length
of the cable required and the number of
cables required. Furthermore, since devices
that communicate through fieldbus require a
microprocessor, multiple points are typically
provided by the same device. Some fieldbus
devices now support control schemes such
as PID control on the device side instead of
forcing the controller to do the processing.
The Power Focus 6000 currently (release 2.1)
supports three different fieldbus types:
• DeviceNet
• EtherNet/IP
• ProfiNetIO
You can set up the fieldbus parameters using Tool Talk 2. For a full overview
of how this is done, please see the user guide for Tool Talk 2.
In short, the value of using a fieldbus communication is to have a real-time
control over multiple controllers in a standardized way in your production
plant.
Please note that there are a couple of fieldbus types available in the Power
Focus 4000 that are not yet implemented on the Power Focus 6000 platform.
