S600+ Instruction Manual
Revised July-2017 Chromatographs C-7
If the keypad set is valid, the system normalises it and then copies
it to the in-use set
If the keypad set is invalid, an alarm is raised and the in-use set
remains intact.
C.4 Configuration Type: 2551/2350 Euro
For this configuration, use PCSetup to preconfigure the master Modbus
interface. The master Modbus process interfaces to the 2551/2350 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.
Note: The process of configuring a 2551 and 2350 Euro
chromatograph is identical. For that reason, we use 2551 to
refer to both the 2551 and 2350 devices.
Refer to Section C.3, Configuration Type: Keypad Mole Percentage
Set Only, for information on setting the keypad percentage set.
C.4.1 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.
If configured for telemetry, then set next
stage to Wait for status data Reply (1).
Delay, then set the flag for the Modbus
master process to poll for status data at
data addresses 3041 to 3061.
