5.2.4 Environment
The ‘Environment I/O’ interface is an independent sub-module within the Solar 2 unit. It is
accessible from and available to any of the main modules that are fitted to the unit. Consequently,
any action or setting applied through one module is visible to and open to change through another
module. If this page is viewed through the TM ET there will be tabs for ‘Alarms’ that are not shown
on the NI ET – see
Section 12 – Alarms
for full details of this function.
The ‘Environment’ page of the ‘NI Engineering’ facility is shown below in
Figure 48

These connections are arranged in two groups of eight, which reflects the fact that each point in
the group is electrically connected to the same physical device (integrated circuit). This has no
significance as far as operation is concerned but will limit the total load current that can be
switched by all the outputs in a group – see
Part 1, Section 3.2
. The following information applies
equally to both groups.
