Hardware Manual COMBILOG 1020

Configure all slave modules with the same bus parameters as
the master datalogger (same protocol type, same baudrate
and parity). All modules must have different modules ad-
dresses.
Connect the master datalogger via RS232 with the host PC
and start the configuration program.
Set the bus parameter for the master function with
module
settings.
Baudrate is selectable between 2400 and 38400 bps
and independent of the settings of the RS232 interface.
Select all values to be measured by the master datalogger by
defining the module address and the channel number of the
corresponding slave module. Up to 60 external channels can
be selected.
Connect all slave modules with the master via the RS485 bus.
After downloading the configuration to the master datalogger
the data transmission between master and slave modules is
started.
Note, that the configuration of slave modules is not possible after
activating the master function.
All collected slave values will be added to the normal dataset,
that is defined by the logging function of the master. No further
calculation (averaging etc.) is executed. If averaging is neces-
sary, use the
read
function of the arithmetic channel!
The scan rate corresponds to the “Logging Interval”
Within one RS485 bus system, only one COMBILOG 1020 can
be defined as master.
