Diagnostics Wire break
Enable diagnostics (for one DIQ channel or all DIQ channels).
You can enable diagnostics for an activated DIQ channel.
The diagnostics monitors the DIQ channel and signals when the line to the actuator is
interrupted.
Distributed I/O devices - field of use
When structuring a system the inputs and outputs from or to the process are often integrated
centrally into the automation system.
In the case of large distances of the inputs and outputs from the automation system the wiring
can become very extensive and unstructured. Electromagnetic interferences can impair the
reliability. The flexibility of a central installation is also limited.
The use of distributed I/Os is suitable for such systems:
● The automation system is located at a central position.
● The I/O devices (inputs and outputs) operate decentrally on site.
● The CFU PA with its integrated BusLink between PROFINET IO and PROFIBUS PA
enables decentralized connection of PA field devices to the CPU of the automation system.
Distributed I/O system
System with input and output modules that are configured on a distributed basis, far away from
the CPU controlling them.
DP
DQ channel
For the "Counter" mode, enables the selection of a free channel to output the comparison event.
Earth
Conductive earth whose electrical potential can be set equal to zero at any point.
