C.7 Configuration Type: Generic
For this configuration, use PCSetup to pre-configure the master
Modbus interface. The master Modbus process interfaces to the unit as
instructed by the chromatograph data handling software. The system
can then perform a controlled, sequential series of polls, enabling the
orderly acquisition of analysis report data.
Keypad Mole
Percentage Set
Refer to Section C.3, Configuration Type: Keypad Mole Percentage
Set Only, for information on setting the keypad percentage set.
C.7.1 Telemetry Stages
Data acquisition occurs over a number of stages, during which the data
handling module interacts with the Modbus master module to control
the order of telemetry polling. The Siemens unit requires polling for
status and analysis data in an alternating sequence each time the unit is
polled.
Stage
Description
1
Idle
If configured for telemetry and this is the
first time of polling for data send a poll
requesting the status of the unit.
Otherwise send a poll to request the
analysis data.
