ADVANCED FEATURES
The Novo can be used with PLC or SCADA-type host products that can monitor
and alert when a decoder fails to turn "on" or "off. " There are 3 relay terminals,
Normally Open (NO), Common (COM) and Normally Closed (NC) available,
see Figure 17-2 to locate these terminals. This requires a hardwire path between
the Novo and a PLC or SCADA product for this advanced feature to operate.
When connected to a PLC or SCADA product and a faulty station is being
operated, the NO and COM are connected.
Pressing the OFF button,
immediately stops any currently
operating irrigation and turns
off power to the 2Wire path to
decoders.
The Novo is turned off until the
"Run" menu is selected.
See Figure 19-1.
