Virtual EventSensor Setup
Via Scriptin
g, the T850 supports a “virtual EventSensor”. This in an allocation in RAM with 48 analog sensor values.
The sensors on this Virtual EventSensor can be read with the usual keys. There can be only one Virtual EventSensor
on a T850. A Virtual EventSensor
behaves like a ‘real’ or physical EventSensor with regards to events, actions, and
SNMP. Unlike a physical EventSensor, a Virtual EventSensor’s sensor value keys are writable.
The Virtual EventSensor allows a script to populate sensor values based on some custom functionality, like querying a
thrid part sensor via serial port or network. With some scripting customization, a third party sensor can be treated as
one of the T850’s EventSensors, bringing it under the umbrella of consistent SNMP access and event/action
management.
The script calls
a_lib.InitVirtualES . This allocates the Virtual EventSensor. From there, the script can write sensor
values to it (and read them). Configure events and actions for it as you normally would for any other kind of
EventSensor.
