• 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

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)

modules.
