Network Status
Indicator State Summary Requirement
Steady Off

a recoverable minor fault,
the module status indica-
tor shall be flashing red.
NOTE: An incorrect or
inconsistent configuration
would be considered a mi-

Module Status (cont.)
Indicator State Summary Requirement
Steady Red Major fault
If the device has detected
a non-recoverable major
fault, the module status
indicator shall be steady
red.

forming its power up
testing, the module status
indicator shall be flashing

Link Status
Indicator State Summary Requirement
Steady Off
Not powered,
unknown link
speed
If the device cannot
determine link speed
or power is off, the net-
work status indicator
shall be steady off.
Red
Link speed = 10
Mbit
If the device is commu-
nicating at 10 Mbit, the
link LED will be red..
Green
Link speed =
100 Mbit
If the device is com-
municating at 100 Mbit,
the link LED will be
green.

ity
If the MAC detects activ-
ity, the LED will be flash-

lision, the LED will be
red.
Using Profibus DP
Communications To/From Third Party Device:
The RUI/GTW equipped with the Profibus DP proto-
col supports cyclic (DP-V0) and acyclic (DP-V1) com-
munications. For your reference, cyclic communica-
tions implies that a set of defined parameters (user
configured as it relates to the RUI/GTW) are periodi-
cally read and or written. The frequency or period of
the read/write operations is determined (setup) via
the Master on the network. You can configure the
cyclic parameter set by installing the software (Pro-
fibus GSD Editor for EZ-ZONE Products) which can
be found on the CD that came with the product (Con-
troller Support Tools) or by clicking on the link below
where it can be downloaded free of charge. Once the
GSD (Generic Station Description) file is created,
simply upload it to the Master device.

Acyclic communications will read and or write data
on demand and is based on the Slot Offset and the
specific index for any given parameter. Most of the
discussion that follows is related to acyclic communi-
cations.
