The controller is produced in 2 versions (by type of connected device):
-
V version group (compatible with the computer):
-
R version group (compatible with the flow meter):
The V and R versions differ in software settings.
When operating with a computer (V version group):
The controllers are used to transfer the parameters of the measured medium to telemetry systems using an interface with the HART protocol (Rev. 5). The controllers receive all universal HART commands (Rev. 5).
When operating with a flow meter (R version group):
The controllers are used as a HART slave device (Rev. 5) for reading the flow rate of the measured medium and diagnostics by HART masters.
Input signals and external interface parameters
Controllers of the V version group enable data exchange with the computer when wired via the RS-232 interface at a speed of 9,600 bps.
Key features
The controller operation allows:
-
When operating with a computer - polling the wired computer and obtaining the instantaneous value of the required parameter, followed by the generation of the output signal according to the HART protocol;
-
When operating with a flow meter - polling the wired flow meter and obtaining an instantaneous value of volumetric gas discharge or steam mass flow, followed by the generation of the output signal, which is proportional to the flow, according to the HART protocol.
