Connecting external pressure and temperature sensors to the electronics
It is possible to connect external pressure and temperature transmitters via HART to the
electronics of the FLOWSIC600-XT. Select the electronics version with the option “HART p/T
modules” in this case. This is available in all three Ex versions (Ex i, Ex d, Ex e) (Table 3
“Available input/output configurations” p. 52).
When the transmitters of the HART masters are connected, the FLOWSIC600-XT
electronics polls the connected HART transmitters for pressure and temperature cyclically
when the parameters are set accordingly (Register #4430 “UART3_Protocol” --> “HART-
PT”). The cycle times can be set between 2 and 60 seconds in Register #4700 “PT_Update
-
Cycle”. Both cycle times are updated within this cycle.
The interface parameters are automatically set to the values 1200 Baud, 8O1.
The pressure transmitter address must be stored in Register #4750
“Pressure_HART_Addr” and the temperature transmitter address in Register # 4751
“Temperature_HART_Addr”.
To use the read-in values, for example, in a volume converter, the raw values for pressure
are available in Register #4723 “Pressure_Raw” and for temperature in Register #4728
“Temperature_Raw”. The transmitter statuses are available in Registers #4727
“Pressure_Status” (for pressure) and #4732 “Temperature_Status” (for temperature).
