Configuration/Setup of a device node

7 .4 .1

Introduction

As described in section 4.1.7, you can use three methods for configuration:
• Manual
• Via DCS template
• Using Wizards/Methods
Note that not all parameters can be configured through wizards/methods. Setting
the monitored segments, non-scanning segment values to null, and alarms to latch
require manual configuration.
7 .4 .2

Manual or via DCS template

Parameters that can be configured are:
• Device tag
You may enter a tag for the device to support identification. As all bus
communication is address-based, the device address is of highest
importance.
• Device signal amplitude limits
The physical layer standard IEC 61158-2 specifies transmit levels of 750 mV
to 1000 mV under test conditions with two terminators. Under plant
conditions, the actual values will differ from segment to segment, and under
some circumstances even significantly.
Values down to 550 mV and up to 1200 mV should however cover most
applications.
Symbol / Alert
When an established device is
removed from a segment, this
(symbol only)
alert is displayed for one hour. It
does not set the 'Device needs
maintenance soon' bit.
When new device is added to
segment, this alert is displayed
(symbol only)
for one hour. It does not set the
'Device needs maintenance
soon' bit.
This device address was used by
a device at some point in time,
(symbol only)
but is no longer in use. If 'device
removed' is displayed, this device
was removed within the past
one hour.
