Control Solutions’ AddMe II
features 16 universal inputs with changeable network variable types.
The universal inputs are context sensitive. When configured as an
analog input, the continuously self-calibrating sigma-delta
converter produces 15-bit resolution with high noise immunity. When
configured as a discrete input, the converter switches to 8-bit
resolution at 128 samples per second for fast response.
Network
variables for the analog I/O points may be configured for any scalar
LonMark SNVT, fixed point or floating point. In addition, analog
(universal) inputs may be configured to SNVT_switch with the on
threshold programmed via the translation tables. Translation tables
allow linearization of type II or type III thermistors or other
nonlinear sensors. Both 3K and 10K thermistors can be connected
directly to analog inputs. A 24VDC excitation output is also provided
for sourcing up to sixteen 20mA sensor loops.
Only
LonMark standard variable types and configuration properties are used.
The standard LonMark Object plug-in, or LonMaker browser, can be used
to do all necessary configuration. Send times for network traffic
throttling and heartbeat, send on delta, object override, etc., are all
supported per LonMark standards.
The
analog sensor inputs include the full complement of LonMark alarm
features. Each input has two high and two low alarm limits with
hysteresis. Alarms are reported via the node object nvoAlarm2, and also
appear in the sensor’s object status.
