For Analog Output Module (AOM4), in case of failsafe condition, the module
continues to drive the old value. In case of power-off condition, the module drives 0
mA current.

Local/Remote mode

RIO600 can be set to Local/Remote mode using any of the binary input signals,
GOOSE signal or through a Modbus command. The Local/Remote mode can be
instantiated using Signal Matrix tool. Different combinations are possible based on
the Local/Remote setting.

Time synchronization

RIO600 can be synchronized to an NTP time server or the time synchronization can
be achieved using Modbus TCP client.
Time synchronization is used to synchronize the device's real time clock. Using time
synchronization, RIO600 can show the correct time in its WHMI and time stamp the
header and data events of GOOSE messages properly.
Time synchronization is not mandatory. The time stamp attribute is
not included by default in GOOSE data sets.
RIO600 does not support DST and therefore the used time is always
UTC in WHMI and events.
