Diagnostics
In the event of a malfunction,
diagnostic messages speed up the
troubleshooting process. Messages are
available locally when using the optional
DOP and via the SFC.
When operating in the DE mode, similar
interface operations are possible
through displays at the Universal
Station
X
(U
X
S) or the Global User
Station (GUS) in the TPS system.
Digital Communications
Summary
The SFC (model STS103) can be used
to “talk” to a flowmeter operating in
either the analog or the DE (Digital
Enhanced) mode. The SFC is
connected across the current line at the
flowmeter or any convenient point in the
line. See Specification 34-ST-03-55 for
more details about the SFC.
To “talk” to a flowmeter through displays
at the Universal Station or GUS, the
transmitter is connected to a Smart MV
Transmitter Interface Input/Output
Processor (STI IOP) in the Process
Manager (PM), Advanced Process
Manger (APM), or High-Performance
Process Manager (HPM) through an
FTA as shown in Figure 6. The flowmeter
must be in the DE mode to communicate
with the STI IOP.
Also, through a custom FTA the
flowmeter, in the DE mode, can
communicate with Allen-Bradley
controllers.
