IsoAir 310P Data Access Tags
Regardless of the Data Collection System, the IsoAir 310P particle sensor will present
a fixed number of data tags that can be grouped by the designated OPC client. All of
the tags presented are read-only. The IsoAir 310P particle sensor is intended to be used
by a single client. There is no limit to the number of available connections.
