User Manual

SGD-SB2025NT-TUM, Part 2
Jan 12 Page 22 NI ET
2.3.1 Address
This indicates the role of the NI in the context of the Solar network. It is not manually entered as it
is derived automatically when the NI is allocated to a role by the TM during the TM configuration
process.
The prefix ‘CEN’ indicates that the mode is “Central” and the prefix ‘STN’ indicates the mode is
“Station”. The suffix indicates the operating number that this unit has been assigned; for Central
the number is in the range of 1 to 16, for Stations 1 to 32.
2.3.2 Name
This is a user defined text label to aid identification of the NI. The name will be displayed in some
of the TM ET windows to assist the user by confirming that the NI being viewed or altered is the
correct one. The process to enter text for the name is detailed in Section 5.2.3.1 – Name .
2.3.3 Channel
This shows the current channel assignment of the NI in the multi-channel versions of TM. For
single channel versions this will always be 1.
2.3.4 Iso I/P and Iso O/P
The application of an input condition to an ‘Iso I/P’ (Isolated Input) or activation of an ‘Iso O/P’
(Isolated Output) will be shown by the associated indicator being lit Yellow . Each input and output
can be named by the user to aid identification of the role assigned to each function.
For further information on the setup options for these inputs and outputs, see Section 5.2.2.4 –
Isolated Inputs and Section 5.2.2.5 – Isolated Outputs respectively. Any Isolated I/P may be
assigned to “Alarm” status – see Section 12 – Alarms .
2.4 NI S TATUS P AGE – LOWER AREA
The information in the Network and PLL areas rotate to show the full set of details; the Network
area taking two rotations and the PLL area three rotations as shown below in Figure 12 .

2.4.1 Network
2.4.1.1 In/Out
The ‘Network’ ‘In/Out’ indications are designed to show if data flow fails in either direction, with the
indications turning Red if data flow is lost. However, the way in which IP networks operate mean
that one way data flow is an unlikely condition. Clearly, the NI will be aware when the incoming
data fails, however, knowledge that packets are being received by the TM is made evident to the
NI by information in the packets sent from the TM.
