disconnection of the affected system components as well as
alerting e.g. by triggering a warning light. Thanks to adjustable
delay times the 3UG4 monitoring relays can respond very flexi-
bly to brief faults such as voltage dips or load changes and can
thus avoid unnecessary alarms and disconnections and in-
crease system availability.
3UG48 monitoring relays for IO-Link
The SIRIUS 3UG48 monitoring relays for IO-Link also offer many
other options based upon the monitoring functions of the tried-
and-tested SIRIUS 3UG4 monitoring relays:
•
Measured value transmission to a controller, including resolu-
tion and unit, may be parameterizable as to which value is
cyclically transmitted
•
Transmission of alarm flags to a controller
•
通过查询对故障的原因进行全面诊断能力
in the diagnosis data record
•
Remote parameterization is also possible, in addition to or
instead of local parameterization
•
Rapid parameterization of the same devices by duplication of
the parameterization in the controller
•
通过IO-Link上传到控制器的参数传输
call or by parameter server (if IO-Link master from IO-Link
Specification V 1.1 and higher is used)
•
Consistent central data storage in the event of parameter
change locally or via a controller
•
Automatic reparameterizing when devices are exchanged
•
Blocking of local parameterization via IO-Link possible
•
Faults are saved in parameterizable and non-volatile fashion
to prevent an automatic start-up after voltage failure and to
make sure diagnostics data is not lost
•
Integration into the automation level provides the option of
parameterizing the monitoring relays at any time via a display
unit, or displaying the measured values in a control room or
locally at the machine/control cabinet.
Even without communication via IO-Link the devices continue to
function fully autonomously:
•
Parameterization can take place locally at the device, inde-
pendently of a controller.
•
In the event of failure or before the controller becomes avail-
able the monitoring relays work as long as the control supply
voltage (24 V DC) is present.
•
If the monitoring relays are operated without the controller,
the 3UG48 monitoring relays have, thanks to the integrated
SIO mode, an additional semiconductor output, which
switches when the adjustable warning threshold is exceeded.
Thanks to the combination of autonomous monitoring relay func-
tion and integrated IO-Link communication, redundant sensors
and/or analog signal converters – which previously took over the
transmission of measured values to a controller, leading to con-
siderable extra cost and wiring outlay – are no longer needed.
Because the output relays are still present, the monitoring relays
increase the functional reliability of the system, since the control-
ler can only fulfill the control tasks if the current measured values
are available, whereas the output relays can also be used for the
disconnection of the system if limit values that cannot be
reached during operation are exceeded.
The individual 3UG48 monitoring relays for IO-Link offer the
以下函数以不同的组合：

Notes on safety:
System networking requires suitable protective measures
(including network segmentation for IT security) in order to
确保安全厂运行。
