Setting the reported value
Though the output switch state is driven by command from the control host, the 702 then
reports back the state of the output switch via the PV and SV. There are various pairs of discrete
states that correspond to an open or closed output switch. This pair of discrete states is called
the Reported Value and can be set in AMS Device Manager by going to Configure > Manual
Setup > Discrete Channels > Setup Channel X (1 or 2). Under Reported Value there is a drop
down menu of choices. The Reported Value can be set independently for each of the two
channels.
Reported Value:
Table 9-4
gives the Reported Value choices and the names for each possible
state of the output switch. Also given are the corresponding Analog Value and Discrete Value for
each possible state.
Value Name: The Name of the reported value will be seen in AMS Device Manager, and on the
device display. The device display may shorten the Name to fit the available display segments.
Analog Value: The Analog Value is seen on the Gateway web interface under the PV or SV. This is
also the value that is reported through the Gateway to a control host that requires an analog
floating point value for PV or SV.
Discrete Value: The Discrete Value is reported through the gateway to a control host that
requires the true discrete state value, rather than the floating point decimal of the Analog Value.
