Emerson FloBoss S600+ User Manual

S600+ Instruction Manual
Revised July-2017 Chromatographs C-3
Mode Handling
Note
The individual stream RD and CV modes (provided they are in
“keypad” or “chromat” mode) can track the individual stream mole %
selection (keypad or chromat).
C.1.4 Multiple Metering Streams Separately Assigned to a Stream
In this situation, a station-to-chromatograph link exists but the
chromatograph is configured to analyse a number of cycle streams
where these streams may be assigned to separate metering streams in
the S600+.
The intent is that the station performs all the Modbus polling but
matches the cycle stream from the analysis report with any from the
list of metering streams to identify it.
Each metering stream must be configured as having the same
chromatograph type, port number and slave address as the station.
Only the cycle stream should be unique.

Note
The individual stream RD and CV modes (provided they are in
“keypad” or “chromat” mode) can track the individual stream mole %
selection (keypad or chromat).
C.1.5 Multiple S600+s Connected to a Single Chromatograph
In this situation, individual S600+s poll a single chromatograph via a
data concentrator. The module does not synchorise polling between
the S600+s. The concentrator is expected to cleanly separate the
messages so that a channel between the S600+ and the chromatograph,
once opened, is not disturbed by the other S600+s.
Each S600+ is expected to have a unique cycle stream so that when the
chromatograph flags that a new report is available, each S600+ takes
one of two possible courses of action:
 If the report stream matches the S600+ cycle stream, then the
S600+ locks into a data acquisition sequence for the mole
percentage data etc. At the end of this and after a delay, the new
data flag resets.
 If the report stream does not match the S600+ cycle stream, then
the S600+ delays polling. After this delay, the S600+ polls again; if
the new data flag is still set, then the new data flag resets.
C.2 Inputs and Outputs
The chromatograph application interfaces indirectly with the
chromatograph via a set of S600+ data points (described by the
PCSetup-generated Modbus map). The application steers the order of
S600+ to chromatograph Modbus polling for status data, mole
percentages, and so on.
