Device Status

The Device Status indicates the current status of the
device or of the directly connected peripherals. This
functionality is part of the IO-Link specification.
The following states are output by the device:
– Device is operating properly (device is functioning
error-free)
This status indicates that no serious error has occurred
in the device and the device can be operated without
restrictions.
– Maintenance-Required
Although the process data is valid, internal diagnosis
functions show that the device or the operational
environment of the device should be serviced.
–
Out-of-Specification
Although the process data is valid, internal diagnosis
functions show that the device is operating outside of
the specified specification. This can affect both the
measurement application itself as well as the
environmental conditions.
– Functional-Check
Process data is temporarily invalid while a deliberate
intervention is performed on the device. For example,
parameterization processes or teach-in.
– Failure
The device or the connected peripherals have a severe
error. The device cannot perform its intended function!
For further information, see section 6.1 on page 45.
The creation of the Device Status is always based on the
output of diagnosis messages. A Device Status is output
for every diagnosis message (event). Each of these can be
found in the event overview list (see section 3.5 on
page 15) or in the description of the functions.
2.6 Block Parameterization
Block parameterization refers to a special process in which
multiple parameters are parameterized in one process. It is
started with a start command and concluded with an end
command.
Because the check of the data is not performed until the
parameterization is concluded, pieces of data that are
dependent on one another can also be set without
problem.

2.7 Data Storage
Data Storage refers to a special process for being able to
store the parameterization data of a device on the master.
The master controls the process between uploads (if data
is intentionally changed) or downloads (if, e.g., an
incorrectly parameterized device is connected). The
system comprising master and device thereby ensures that
a device can be exchanged without the need for an active
re-parameterization.
The settings regarding Data Storage are to be
performed on the IO-Link master gateway (refer to
the information in the corresponding
documentation).
Operation is dependent on the used IO-Link master and is
explained in the corresponding description.
All parameters that are stored for parameter
management in the IO-Link master are marked
appropriately in Tab. 3-1 (see ISDU – Identification
Data on page 8).
2.8 Reset Commands
The device offers various reset functions. A corresponding
command is executed via a system command.
The behavior and the values that are reset in a given case
can be found in the ISDU overview (see section 3.3 on
page 8) and in the individual function descriptions.
The Reset Commands are described on page 49.
2.9 Device Functions and Master Gateway
The functions of the device are described in detail in the
subsequent sections. Refer to the guide of the IO-Link
master for information on the implementation of the
process, parameter and diagnostic data via the master
gateway.
