TPRN
equipment. The default status of these input ports can be defi ned through the Supervision
System. After that, any change from default status will be revealed as a failure signal.
• a summary of major and minor alarms related to failures detected not only on the TPRN
sub-rack, but also on any active modules hosted by the TPRN itself.
• 2 relay output ports, which be can used to drive any external device connected to subD-
15 pins adapter. By using the Supervision System, each of these output ports be can set
up in “open” or “close” modes.
A more detailed description of the meaning and functionality of each pin is reported in Table
8. The pins are numbered from left to right, and from top to bottom (refer to Fig. 4.1.8).
Note: The TPRN sub-rack uses I2Cbus standard protocol to collect status and alarm information
from hosted modules. Thanks to that, the alarm summaries (provided through pins 5-6 and 7-8)
report major and minor failures related not only to the TPRN sub-rack but also to any hosted
modules.
